                               ABSTRACT
This report presents the findings of the Phase II "Program For Reduc-
tion of NO  From Tangentially Coal Fired Boilers" performed under the
          n
sponsorship of the Office of Research and Development of the Environ-
mental Protection Agency (Contract 68-02-1367).  Phase I of the program
consisted of selecting the Alabama Power Company, Barry Station #2 steam
generator which was modified for the studies performed under Phase II.
The Phase I results were presented in final  report EPA-650/2-73-005,
dated August, 1973.

The work accomplished under Phase II included the design, fabrication,
and delivery of an overfire air system for the test unit, the installa-
tion of test equipment, planning, and the conducting of baseline, biased
firing and overfire air studies for NO  emission control while burning
a Kentucky bituminous coal type.
These test programs included an evaluation of the effect of variations
in excess air, unit slagging, load and overfire air on unit performance
and emission levels.  Additionally, the effect of biasing combustion air
through various out of service fuel nozzle elevations was also evaluat-
ed.  The effect of biased firing and overfire air operation on waterwall
corrosion potential was evaluated during three thirty (30) day base-
line, biased firing and overfire air corrosion coupon tests.

Unit loading and waterwall  slag conditions exhibited minimal effects on
NO  emission levels while reductions in excess air levels and overfire
air operation were found to be effective in reducing NO  emission lev-

                              CONCLUSIONS
Normal Operation
1.  Under normal unit operation without overfire air, excess air varia-
    tion was found to have the greatest single effect on NO  emission
                                                           A
    levels, increasing NOV with increasing excess air.  An average in-
                            6
    crease of 0.014 g N0/10 cal for each 1% change in excess air was
    observed over the normal operating range.
2.  Unit loading and variation in furnace slag conditions were found to
    have the least effect on NO  and CO emission levels and the percent
                               A
    carbon in the flyash.
3.  Under normal unit operation, the percent carbon loss in the fly ash
    and CO emission levels increased with decreasing excess air with the
    increases becoming greater below a level  of approximately 20 to 25
    percent excess air.  CO levels in excess  of 0.1  g/106cal  were con-
    sidered unacceptable for the purposes of  this program.
Overfire Air Operation
1.  NO  reductions of 20 to 30% were obtained with 15 to 20 percent
      n
    overfire air when operating at a total  unit excess air of approxi-
    mately 15 percent as measured at the economizer outlet.  This con-
    dition would provide an average fuel firing zone stoichiometry of
    95 to 100 percent of theoretical air.   Stoichiometries below this
    level did not result in large enough decreases in NO  levels to jus-
                                                        A
    tify their use.  Biased firing, while potentially as effective,
    necessitates a reduction in unit loading and is therefore less de-
    sirable as a method of NO  control.
                             A
2.  When using overfire air as a means of decreasing the theoretical
    air (TA)* to the fuel firing zone the percent carbon in the fly ash
    and CO emission levels were less affected than when operating with
   See Appendix I.

-------
    low excess air.  This is due to the ability to maintain acceptable
    total excess air levels during overfire air operation.
3.  Furnace performance as indicated by waterwall slag accumulations,
    visual observations and absorption rates were not significantly af-
    fected by overfire air operation.
4.  On the test unit, where the overfire air port could not be installed
    as a windbox extension, test results indicated that the centerline
    of the overfire air port should be kept within 3 meters of the
    centerline of the top fuel elevation.  Distances greater than 3
    meters did not result in decreased NO  levels.  Changes in distance
                                         A
    less than 3 meters did affect NO  levels to a limited extent with
                                    A
    the NO  level increasing with decreasing distance.
          A
5.  Optimum overfire air operation was obtained with the test unit when
    the overfire air nozzles were tilted with the fuel nozzles.  From a
    standpoint of NO  control, emission levels increased when the noz-
                    A
    zles were directed toward each other, and flame stability decreased
    when they were directed away from each other by more than 20-25.
    With the overfire air tilts fixed in a horizontal position, accept-
    able unit operation was obtained, however, NO  levels varied with
                                                 A
    fuel nozzle position.
6.  The results of the 30 day baseline, biased firing and overfire air
    corrosion coupon runs indicate that the overfire air operation for
    low NOX optimization did not result in significant increases in
    corrosion coupon degradation.  Additional studies will be required
    to verify these observations over long-term operation.
7.  Variables normally used to control normal boiler operation should
    not be considered as NO  controls with coal firing.  These variables
                           A
    include unit load, nozzle tilt, pulverizer fineness, windbox dampers
    and total excess air.
8.  Overall unit efficiency was not significantly affected by overfire
    air operation.

-------
                            RECOMMENDATIONS
This program Investigated the effects of employing biased firing and
overflre air, as Incorporated on a specially modified unit, as methods
for controlling NO  emission levels In existing steam generating units.
                  n

These control methods were studied using an Eastern United States bi-
tuminous coal type.  Due to the location of the test site it was not,
however, within the scope of this program to Investigate coal types lo-
cated In the western areas of the United States.

1.  As these western coal types are becoming a more predominate source
    of fuel for electric generating stations, It was recommended In the
    Task V Interim report that studies be undertaken to Include their
    evaluation.  EPA Contract 68-02-1486 was subsequently awarded to
    Combustion Engineering, Inc. to study western coal fuels.  In this
    program new units being designed with overfire air systems as an
    extension to the windbox will be utilized eliminating the need for
    unit modifications while expanding the experimental studies to In-
    clude test data for larger current design steam generating units.
2.  Additionally, the results of the corrosion probe evaluations indi-
    cate that the coupon weight losses encountered during a 30 day eval-
    uation are small and consideration should be given to studies of up
    to one year duration to verify short term test results.  These
    studies should include evaluation of actual fireside waterwall tube
    wastage rates as well as corrosion probe wastage rates.

Purpose and Scope
This program encompassed the work to be performed under the second phase
of a two phase program to identify, develop and recommend the most prom-
ising combustion modification techniques for the reduction of NOX emis-
sions from tangentially coal-fired utility boilers with a minimum impact
on unit performance.

Phase I (performed under EPA Contract 68-02-0264) consisted of select-
ing a suitable utility field boiler to be modified for experimental
studies to evaluate NO  emission control.  Phase I also included the
                      A
preparation of preliminary drawings, a detailed preliminary test pro-
gram, a cost estimate and detailed schedule of the program phases and a
preliminary application economic study indicating the cost range of a
variety of combustion modification techniques applicable to existing and
new boilers. ^ '

Phase II consisted of modifying and testing the utility boiler selected
in Phase I to evaluate overfire air and biased firing as methods for NO
                                                                       A
control.  This phase also included the completion of detailed fabrica-
tion and erection drawings, installation of analytical test equipment,
updating of the preliminary test program, analysis and reporting of test
results and the development of control technology application guidelines
for existing and new tangentially coal-fired utility boilers.

This program was conducted at the Barry Steam Station, Unit No. 2 of
the Alabama Power Company.  This unit is a natural circulation, bal-
anced draft design, firing coal through four elevations of tilting tan-
gential fuel nozzles.  Unit capacity at maximum continuous rating (NCR)
is 408,000 kg/hr main steam flow with a superheat outlet temperature and
                                 p
pressure of 538C and 131.8 kg/cm .  Superheat and reheat temperatures
are controlled by fuel nozzle tilt and spray desuperheating.  A side

                              OBJECTIVES
 The objective of program  Phase  II was to complete the design of the
 overfire  air  system, modify the Barry 2 unit accordingly, perform base-
 line,  biased  firing and optimization tests and based on the results of
 this program,  prepare an  application guideline for the NOX control
 technology  generated.

 Specifically  these objectives are defined as follows:

 Task I    -  Prepare the design, detailed fabrication and erection draw-
            ings  necessary for modification of Barry No. 2 to incorpo-
            rate  an overfire air system.  The system design provides for:
            a.  Introducing a maximum of 20% of the total combustion air
               above the  fuel admission nozzles.
            b.  Overfire air introduction through the top two existing
               windbox compartments (thereby prohibiting the use of one
               elevation of fuel nozzles).
            c.  Introduction of hot overfire air only with consideration
               for air preheat control.

           An updated schedule for Tasks II and IV were also prepared
            under Task I.

Task II  -  Complete the purchasing and fabrication of all  equipment
           necessary for modification of the Barry No.  2 unit.

Task III -  Install all  necessary instrumentation required to measure
           flue gas constituents and characterize the effects of com-
           bustion modifications on unit performance.  Specifically the
           following determinations were made:
           a.   Flue gas constituents:  NOX, SOX, CO, HC, 02
           b.   Unit Performance Effects:

-------
               Fireside corrosion
               Furnace heat absorption
               Sensible heat leaving furnace
               Superheater, reheater and air heater performance

Task IV  - Conduct a baseline test program to establish the effect of
           unit load, wall slagging and excess air variation on base-
           line emission levels, thermal performance and operating
           ranges.  A baseline corrosion coupon test of 30 day duration
           was also conducted.

Task V   - Conduct a biased firing baseline test program to establish
           the effect on unit emission levels while operating with
           various fuel elevations out of service.  These tests were
           performed specifically to evaluate the maximum emission con-
           trol at full load and throughout the normal load range.  In
           addition, the degree of control required to meet and maintain
           emission standards throughout the normal control range was
           also evaluated.  A biased firing corrosion coupon test of 30
           days duration was also conducted.

Task VI  - Install all equipment required for modification of the test
           unit and functionally check equipment to determine that prop-
           er operation is obtained.  (See Figure 1A)

Task VII - Complete final preparations for conducting the overfire air
           test program to be conducted in Task VIII including the
           f ol 1 owi ng:
           a.  Finish installation of the furnace waterwall thermo-
               couples.
           b.  Check out all necessary test instrumentation for proper
               installation and operation.
           c.  Review test program with EPA project officer and util-
                                   8

 Task  VIII-  Conduct  the  overfire air test program, analyze the data gen-
            erated and compare this data with that obtained during Task
            V.   The  program investigated the effect of overfire air lo-
            cation and rate at various unit loadings and evaluated op-
            erating  conditions considered as optimum from the standpoint
            of NO  control and unit operation.  The final report was
            also generated under this Task.

 Task  IX  -  Prepare a program outlining the application of the technology
            developed under this study to existing and new design tan-
            gentially coal-fired utility boilers.  These application
            guidelines will be submitted as a separate final  report.
*  The test program for this study was originated during the Phase I
   study, Contract 68-02-0264 and was included as part of the Phase I
   report.

                               DISCUSSION
 Task I  - Prepare  the  Design. Detailed Fabrication and Erection Drawings
 Engineering  Drawings
 The drawings necessary  for  the design and installation of the overfire
 air system were completed by the end of the eighth program month and
 were submitted to the EPA for  review and approval as they were com-
 pleted.   The design provides for the introduction of 20% of the total
 combustion air as overfire  air above the existing fuel admission zone.
 These compartments are  located approximately 2.4 meters above the ex-
 isting windbox.   In addition overfire air can be introduced through the
 top two  compartments of the existing windbox.  The current design pro-
 vides for the introduction  of hot overfire air only.

 Updated  Time Schedule
 The Phase II program schedule was reviewed and updated relative to the
 coordination of Tasks II, IV and V with the test unit outage.

 The scheduling of the unit outage was coordinated with Alabama Power
 Company  and  reviewed periodically to assure that the unit modification
 would occur  as scheduled.  The final program schedule presenting the
 actual periods of performance for Phase II is shown on Figure 2.

 Task  II  - Purchase and Fabricate Equipment
 The equipment for modification of the Barry No,  2 unit to incorporate
 overfire  air as an N0y control  was assembled and ready to be shipped to
 the test site by  the end of the eighth program month.  Completion of
 equipment fabrication by this date permitted necessary time for delivery
 of the equipment  to the job site and performing any possible pre-outage
erection which would be accomplished prior to the unit outage.

 In addition,  instrumentation required for the baseline and optimization
test phases  of the program was  calibrated, fabricated and prepared for
shipment to  the job site.  This effort included  fabrication of corrosion
                                  11

Test Data Acquisition and Analysis
The flue gas samples for determination of NOX> 02> CO, S02 and HC emis-
sion levels were obtained at each of the two economizer outlet ducts.
*  Installed during Task VI
                                  15

-------
The flue gas samples were drawn from a twenty-four (24)  point grid ar-
ranged on centroids of equal area in each duct with the  exception of the
S02 sample which was drawn from a single average point using a heated
sample line.  Fly ash samples for carbon loss analysis and dust loading
were obtained at a single point in each duct.

The percent 02 leaving the air preheaters was also determined using a
twenty-four (24) point grid arranged in centroids of equal area for the
determination of air preheater leakage and unit efficiency.

The following instrumentation was used in determining the emission con-
centrations:

1.  NO :  Chemiluminescence Analyzer
2.  02:   Paramagnetic Analyzer
3.  CO:   Nondispersive Infrared Analyzer
4.  HC:   Flame lonization Analyzer
5.  S02:  Wet Chemistry
6.  Carbon Loss & Dust Loading:  ASME Particulate Sampling Train
A summary of the NO  emission test data is tabulated on Data Sheets  1,
                   A
2, 3 and 4.
Unit steam and gas side performance was monitored using calibrated
thermocouples, pressure gauges, transducers  and manometers  as  required.

Coal samples were obtained during each test  for later analysis.   The
samples were obtained from each feeder and blended to form  a composite
sample.  Fuel analyses, unit steam flow rates, absorption rates,  gas and
air weights and efficiencies were calculated for each test  run.   Unit
efficiency was determined using the heat losses method (based  on  ASME
power test code 4.1-1964).  The measured and calculated unit performance
test data is presented on Data Sheets 5, 6,  7 and 8.   A complete  set of

unit board data was obtained for each test run and is presented on Data
Sheets 9, 10, 11 and 12.  While Data Sheets 1  through 8 are reported in
metric units, the board data (Sheets 9 through 12) are reported in the
engineering units as taken.   The 30 day waterwall corrosion coupon eval-
uation was conducted using a specially designed probe consisting of four
individual coupons shown in Figure 4.  Individual  probes were exposed at

Task IV Baseline Test Study
Load and Excess Air Variation
Tests 1 through 7 were conducted to determine the  effect of varying ex-
cess air at three unit loads on unit emission levels and performance.
These tests were conducted with clean furnace conditions.
As shown in the following table, NO  emission levels increased with
                                   /\
increased excess air but did not change significantly with changes in
unit loading.  An average increase of 0.014 g N02/10  cal  was noted for
each 1% change in excess air over the normal  unit operating range.

A maximum excess air limit of 30.8 and 58.9 percent was obtained at
full and half load conditions respectively due to ID fan capacities.

Minimum excess air limits of 20 to 25 percent were determined as those
at which acceptable CO emission levels could be maintained.  Reduction
of N00 emission levels using excess air reduction was therefore limited
     C.                    g
to approximately 1.04 g/10 cal as obtained during Test 5.

The changes in N02, CO, percent carbon loss in the fly ash and unit
efficiency versus theoretical air to the fuel firing zone are shown on
Figures 7, 8, 9 and 10, respectively.  The theoretical air (TA) to the
firing zone is used in this case as it accounts for variations in posi-
tion and leakage in the compartment dampers above the top active fuel
compartment and thereby presents a more accurate determination of the
actual air available for combustion in the fuel firing zone than does
the total excess air.  As seen on Figure 7 for clean furnace conditions
the NOo correlates well with TA with little variation due to unit load.
As shown on Figures 8 and 9 carbon loss in the fly ash and CO emission
levels increased with decreased TA levels.  Unit load does not appear
to have a discernable effect.  Figure 10 is a plot of Unit Efficiency
versus Unit Excess Air measured at the economizer outlet.

During this portion of the test program total hydrocarbon levels (HC)
were monitored and were found to be present in only trace quantities as
shown on Data Sheets 1 and 2.  The S02 levels measured are also shown on
Data Sheets 1 and 2.

Furnace Mall Deposit Variation
Tests 8 through 14 were conducted to determine the effect on unit per-
formance and emission levels of varying furnace water-wall deposits from
a clean condition to the maximum possible slagging condition obtainable.
The maximum slagging condition was obtained after operation in excess
of twenty-four hours without operating any wall blowers.  During this
                                  21

As can be seen from Figure 7 furnace slagging did not exhibit a dis-
cernable effect on NO  emission levels.  As shown in Figures 8 and 9
                     n
this condition was also found to be true for carbon loss in the fly ash
and CO emission levels with the exception of the half load Tests 11 and
12 where CO levels higher than those obtained with clean furnace condi-
tions were observed.  The high CO levels may have been due to slag build
up at or near the fuel and air nozzles which could have contributed to
poor combustion.  The higher CO levels were not observed under full load
with heavy slag operation.  Figure 10 indicates that furnace cleanliness
did not exhibit any discernable effect on unit efficiency.

Slag patterns taken during clean, moderate and heavy slagging conditions
at full load operation are shown on Figures 11, 12 and 13.

Task V - Biased Firing Study - Fuel  Elevations Out of Service Variation
Tests 15 through 24 were conducted to determine the effect on NO  emis-
sion levels of taking various fuel elevations out of service (biased
firing) at various unit loadings.   As shown on the following table the

maximum NO  emissions control was obtained with the top elevation of
          rt
fuel nozzles out of service at maximum and 75 percent maximum loading
(Tests 20 and 21).  At 50 percent maximum loading (Test 23)  the high
excess air levels required to maintain unit steam temperatures appeared
to negate any NO  reductions obtained by biasing the top fuel nozzle
                A
elevation, however, the emissions level obtained was below the current
EPA limit for coal fired units of 1,26 g/106cal.

As can be seen from Figure 14 biasing the center two and bottom fuel
elevations did not have a discernable effect on NO  emission levels al-
though the emission level tended to be higher at reduced unit loadings
for given TA levels.
Figures 15 and 16 indicate that with biased firing, low TA levels to
the fuel firing zone were obtained without increasing either CO emis-
sion levels or the carbon loss in the fly ash.  Figure 10 shows that
biased firing operation did not significantly affect unit efficiency.
This condition is due to the ability to maintain acceptable total unit
excess air levels during biased firing operation.

Tests 1 through 7 were performed with unit conditions  closely  approxi-
mating those of Baseline Tests 1 - 7 under Program Task  IV.  A clean
furnace was maintained as the excess air was  varied at three unit  loads.

The effect of these operating conditions on emission levels and per-
formance can be seen in the Table above.
As witnessed in the previous baseline tests,  NO  emissions  levels  in-
                                               A
creased with increased excess air.*
   In general, N02 values were slightly lower after modification for
   the same test conditions.   This resulted from an updated firing  system
   installed between the sets of tests  along with an average percent ni-
   trogen in fuel decrease of 0.15 percent (1.21 to 1.06 percent).   Also,
   fuel  higher heating values and furnace outlet temperatures tended to
   be lower for Tests 1 - 7 after modification.
                                  34

 ID  fan capacities limited excess air to a maximum of 64.7 and 33.5 per-
 cent at half and full load conditions respectively.  Acceptable minimum
 excess air limits were established at 20-25 percent to control CO emis-
 sion levels.  Thus, NOU emission levels could only be reduced to approx-
                 6
 imately 0.90 g/10 cal through excess air reduction.  The effect of
 theoretical air to the firing zone on NO , CO, and percent carbon loss
                                        n
 in  the fly ash (% CL) can be seen in Figures 17, 18 and 19.  In agree-
 ment with the original baseline tests, theoretical air to the firing
 zone (TA) was used for comparison in place of total excess air (EA).
 TA  is determined by location and means of admission as well as quantity,
 and consequently better defines that air actually available for initial
 combustion.

 Figure 17 indicates a definite increase in NO  emission levels with in-
                                             n
 creasing TA for clean furnace conditions.  CO emission levels and per-
 cent carbon loss in the fly ash can be seen to increase with decreased
 TA without overfire air.   Reasonable control of CO and % CL can only be
 maintained at TA levels above 120%.  No definite relationship can be
 observed between unit load and CO emission levels.  Percent CL can be
 seen to be greater at higher unit loads for given TA levels.

 Changes in unit efficiency versus excess air at the economizer outlet
 are presented in Figure 20.   Overall, unit efficiency decreases as the
 excess air increases.

Hydrocarbon emission levels  appeared only in trace quantities for this
 portion of the test program.   HC and S02 levels are presented on Data
Sheets 3 and 4.

The effect of furnace waterwall deposits on unit performance and emis-
sion levels was studied in Tests 8 through 14 (Clean Condition - Max-
imum Slagging Conditions).  Dirty conditions were established after a
minimum of 24 hours of no operation of wall blowers.  Deposits of up to
four inches in thickness could subsequently be found in and above the
fuel firing zone.

Figures 17, 18 and 19 reveal no observable effect of furnace cleanli-
ness on NOX or CO emission levels along with percent carbon loss in the
fly ash.*

Slag patterns taken during full load operation for clean, moderate and
heavy slagging furnace conditions can be viewed in Figures 21, 22 and 23.
   Again,  NOX values  were generally  slightly  lower  after modification.
   Nitrogen  in fuel decreased  an  average  of 0.19  percent from  1.23  per-
   cent.   Furnace outlet temperatures were  somewhat lower  for  Tests 8
   through 14 after modification  although fuel  higher  heating  values
   showed  no definite change.

Tests 15 through 23 were performed to establish the effect of overfire

air admission on N0 emission levels.  The unit load and excess air re-
                   A
mained constant for moderately dirty furnace conditions.  Location of

air admission to the furnace was varied.
As shown in Figure 24, this set of tests shows a tendency of NO  emis-
sion levels to decrease with decreased theoretical  air to the firing

zone.  NO  levels are generally higher with ABC mills (top 3 elevations)
in service than with BCD mills (bottom 3 elevations).  Both operating
conditions support the premise of reducing NO  emission levels by re-
                                             /\
ducing the air input to the fuel firing zone and admitting downstream
of that point.  The fire is thereby spread out over more of the furnace
reducing its intensity.  The above factors are limited by flame sta-
bility which became very lazy in Test 18.  By using the bottom 3 ele-
vations in place of the top 3 elevations, the distance between the over-
fire air and the firing zone was increased.  (The mean firing elevation
is also slightly decreased.)  Comparison of Tests 18 and 19 with Tests
22 and 23 reveals lower NO  levels obtained with increased distance be-
                          A
tween the overfire air and the firing zone.  Operation at TA levels be-
low 95X did not result in significant reductions in NO  emission levels.
                                                      n

CO emission levels remained acceptable for the entire set of tests
where the total excess air was approximately 27 percent as shown on
Figure 25.

OFA admission location or rate variation exhibited no significant
change in percent carbon loss in the fly ash as shown on Figure 26.

Unit efficiencies were not significantly affected by fuel elevations in
service, or by overfire air location and rate variation.  This is ex-
plained by the fact that essentially constant total excess air levels
were maintained during this study.

Tests 24 through 30, and 33, were conducted at full unit load with ex-
cess air and theoretical air levels to the firing zone of approximately
24 percent and 92 percent, respectively.  With moderate slagging con-
ditions on the waterwalls the fuel nozzle tilts and OFA tilts were
varied.  This essentially moves the firing zone both in -the furnace and
in its relative position to the overfire air.  Fuel nozzle tilts that
are maximum minus combined with OFA tilts of maximum plus increase the
distance between the overfire air and the firing zone.  As with previous
methods of increasing this distance, the NO  emission levels are de-
                                           /\
creased.  Figure 27 shows that as the tilts are moved toward one an-
other (fuel nozzle tilts up; OFA tilts down), the OFA - firing zone
separation is decreased and the NO  levels are increased.
                                  rt

When the OFA tilts are maximum minus and the fuel nozzle tilts maximum
plus, the term overfire air becomes ambiguous.  The actual overfire air
is less than the reported value, because the air is being forced .down
into the raised firing zone.  At this point where the combined fuel
nozzle and OFA tilt differential is 52 degrees toward each other, the
NO  emission level reaches a maximum of 0.846 g/10 cal.

Percent carbon loss in the flyash exhibits a definite increase as the
fuel nozzle tilts and OFA tilts move away from each other.   This can be
witnessed in Figure 28.

CO emission levels also show an increase as the tilt differential in-
creases, yet there is enough total excess air to maintain an acceptable
emission level as shown in Figure 29.

Flame stability arises as a limiting factor in variation of the tilts.
As the tilts move substantially away from each other, the fire becomes
unstable and pulsing may result.  Test 29 was performed with a fuel noz-
zle and OFA tilt differential of 51 degrees away from each other.  NOV
                                       6
emission levels decreased to 0.596 g/10 cal, yet the CO emission levels
began to increase and the fire appeared less stable.  Maintaining the
fuel nozzle tilts and OFA tilts at approximately equal tilt angles re-
sulted in acceptable flame stability as well as reduced NO  emission
                                                          n
levels.

For all OFA tilt variation tests the NO  emissions level obtained was
below the EPA limit of 1.26 g/106cal.

Load Variation at Optimum Conditions
Tests 30 through 35 were conducted to evaluate unit performance and
emission levels at optimum operating conditions as determined during
Tests 15 through 29.  Tests were conducted over the unit load range at
varying furnace waterwall slagging conditions.  The NO  emission level
                                                      A
results of this series of tests versus unit loading, expressed as main
steam flow, are shown on Figure 30.

This figure illustrates the range of N02 levels obtained both during
baseline (after modification) and optimum unit operations.  Not all  the
baseline tests are included as in some cases unit operation was felt to
depart excessively from normal operations.  Low excess air operation
can be cited as an example.

The wide range of N0 levels obtained, particularly during the base-
line tests are due to variations in unit operating parameters such as
excess air level.  During the optimization tests total excess air at
the unit economizer outlet was maintained between 20 and 28% at full
and 3/4 load and 45 to 47% at 1/2 load and fuel nozzle tilts raised or
lowered as required to maintain acceptable reheat and superheat outlet
temperatures.  Also minimum excess air levels were established on the
basis of maintaining acceptable CO emission levels and flame stability.

Tests 30, 31 and 32 were conducted as a series and no problems were en-
countered while changing load with optimum operation.

Furnace Performance
During the test program furnace performance was monitored by use of
chordal thermocouples installed in the furnace waterwalls.  A schematic
of the thermocouple locations is shown in Figure 31 and a tabulation of
                                  55

 the  absorption  rates obtained Is presented on Sheets 13A, 13B and 13C.
 The  temperatures and corresponding absorption rates were found to vary
 significantly with wall slag conditions making data interpretation
 difficult.  The method finally arrived at as representing an accurate
 indication of furnace performance is as follows:

 The  front and right side wall centertube profiles were plotted as shown
 in Figure 32 and the average of these profiles determined.  It should be
 noted  that the  maximum and minimum profiles shown do not represent in-
 dividual walls  in every case, i.e., at given furnace elevations the max-
 imum rate shown may switch from wall to wall.

 For  comparison  of optimum and normal unit operation with respect to fur-
 nace performance, three full load tests with similar furnace slagging
 conditions, etc., were selected for comparison.  The average centerline
 profiles for these tests (14, 24, 33) were determined, as shown on Fig-
 ures 32, 33 and 34, and then plotted together as shown on Figure 35.  As
 shown, furnace  performance remained essentially unchanged when furnace
 slagging effects are taken into account.

 It should be noted here that obtaining desired slag conditions proved to
 be difficult and somewhat unpredictable during overfire air operation.
 This situation  was most pronounced in the firing zone where slag accu-
 mulations would normally shed themselves before appreciable accumula-
 tions  could be  built up.

 Uaterwall Corrosion Coupon Evaluation
 Following completion of the steady state phases of the baseline, biased
 firing and overfire air test programs, thirty (30) day waterwall corro-
 sion coupon evaluations were performed.  The purpose of these evalua-
 tions was to determine whether any measurable changes in coupon weight
 losses could be obtained for the various firing modes studied.

The corrosion probes used in the evaluations were previously shown on

Figure 4.  The Individual probes were exposed at five locations on the
furnace front wall as shown on Figure 5,  The coupon temperatures were
maintained at the same levels for each 30 day run and a typical trace
of the control temperature range for each of the twenty coupons Is shown
on Figure 6.

The individual coupon weights were determined before and after each
thirty day test and the individual coupon and average probe weight
losses are shown on Sheets 14A, 14B, and 14C.  The weight losses are
                   2
calculated as mg/cm  of coupon surface area.  Of the sixty coupons ex-
posed, three were damaged during disassembly and were therefore not
included in the weight loss determinations.  The affected coupons were
as follows:  Coupon K-l, baseline study, and coupons 2-1 and 2-4 over-
fire air study.  In addition, five coupons from probes T and N of the
overfire air study resisted disassembly and were therefore weighed as
single units and average weight losses were determined.

Figures 36, 37 and 38 show the unit load schedules for each of the
30 day test periods.

The biased firing study was conducted with the top fuel firing eleva-
tion out of service as this operating condition  was shown during steady
state biased firing tests to produce the lowest NO  emission level of
                                                  /\
the biasing modes studied.  The overfire air study was conducted using
an "optimized" operating mode as determined during the overfire air
steady state tests.

Throughout each study the following damper positions were maintained
over the load ranges indicated.

At unit loadings below 204,000 kg/hr steam flow, with two elevations of
mills in service, damper positions were maintained as follows:

The percent oxygen was monitored daily during each thirty day study at
each probe location and was found to be essentially the same for the
various test conditions ranging between 16 and 19 percent Op.


The weight losses calculated for the biased and overfire air portion of
the test program were found to be greater than those for the baseline
tests.  The average weight losses for all five probes were as follows:

   At no time during the biased firing study was the top elevation coal
   pulverizer placed in service.  Maximum unit loading was therefore
   limited to the maximum with the lower three mills in service.

  2.6381 mg/cm2                4.6429 mg/cm2          4.4419 mg/cm2

These values are within the range of losses which would be expected for
oxidation of carbon steel for a 30 day period.   To verify this premise
control studies were conducted in C-E's Kreisinger Development Labora-
tory using probes exposed during the biased firing study.  These probes
were cleaned and prepared in an identical  manner to those used for fur-
nace exposure and placed in a muffle furnace for 30 and 60 day exposures
at 750 F with a fresh air exchange.  The test results were as follows:

                                                2
         Probe                    Wt. Loss mq/cm  - 30 Days
       M (30 day)                               4.7999
       Q (30 day)                               4.7741
       R (60 day)                    5.1571/2 = 2.5785
       B (60 day)                    8.3493/2 =4.1746

These results indicate that the test coupons oxidized more rapidly
during the first 30 days exposure with average weight losses decreas-
ing in the second thirty days.  Based on these results, it appears
that the differences in weight losses observed during the test pro-
gram are within the ranges to be expected from oxidation alone.

Chemical analysis of deposits taken during the test program does not,
in itself, show that molten phase attack  has occurred.  The composition
of the deposits does show some differences, primarily in the iron con-
tent as noted on Figure 39.  The deposit collected during the biased
firing and overfire air tests show 50 and 35 percent iron, respectively,
versus 30 percent in the baseline test.  Higher iron is normally in-
dicative of lower melting temperatures.  However a certain quantity of
CaO is necessary to flux the iron if it is to result in a low melting
mixture.  The CaO content is considerably less in the biased firing and
overfire air tests as compared to that of the baseline test.  According-
                                  68

 ly  the fusibility temperatures are higher for the biased firing test
 and slightly higher  for  the overfire air tests.  This agrees with ob-
 servations made during the tests, i.e., deposits during biased firing
 were more friable and easily removed than in the baseline tests with
 the overfire air tests falling closer to baseline operation.

 For comparison fusibilities and compositions have been given in Figure
 39  for the coal ash  as fired.  This points out the selective deposition
 of  certain constituents  in the coal ash, like iron, and also shows that
 resultant fusibility temperatures of deposits can be significantly diff-
 erent than the coal  ash  as fired.

 Overfire Air Evaluation  - Alternate Coal Types
 The evaluation of alternate coal types with respect to their effect on
 unit performance and NO  emissions optimization was originally proposed
                       A
 as  part of this study.   However, due to coal supply problems encountered
 after the start of work, these evaluations proved to be not feasible and
 were therefore not performed.  Tests of a similar nature evaluating Ala-
 bama and Midwestern  coals were performed during 1973 by Esso Research
 and Engineering Co.  under EPA Contract 68-02-0227 at the Alabama Power
 Co., Barry No. 4 unit.  A discussion of those test results has therefore
 been included in this report/  '

 Unit Description
 Barry No. 4 is a controlled circulation, radiant, reheat, single cell
 pressurized design firing coal  through five elevations of tilting tan-
 gential fuel nozzles.  Maximum continuous rating is 1,164,969 kg/hr
 superheat steam flow at 538C/176 kg/cm2 and 1,024,566 kg/hr reheat
steam flow at 538C/44 kg/cm.  Control load rating is 582,485 kg/hr
main steam flow.

Alabama and Midwest coals plus petroleum coke were fuels being burned
at the time of the test program.  The petroleum coke was fired exclu-
                                  70

sively through the center fuel nozzle (Elevation C) and normally repre-
sented one-quarter to one-fifth of the heat input.

Test Objectives
The objectives of the Esso test program were as follows:

1.  A series of short (thirty minutes) tests for optimizing NO  reduc-
                                                              n
    tion by varying the following:
    A.  Excess Air
    B.  Nozzle Tilt
    C.  Overfire Air
    D.  Primary/Auxiliary Air Damper Settings
    E.  Unit Load
    F.  Pulverizer Coal Fineness
    G.  Firing Alabama Coal, Alabama + Coke and Midwest + Coke

2.  A two or three day sustained operation at optimum NO  reduction op-
    erating conditions for checking possible short term unit operating
    problems.

3.  A three hundred hour operating period at optimum NO  reduction con-
                                                       A
    ditions for determining possible long term operating problems.

Discussion
Test Data Acquisition
Esso Research measured all gas emission levels with instrumentation lo-
cated in a specially designed mobile van.  The van was located at ground
level  and had the following instrumentation:

NO     Thermo Electric Chemiluminescence
N02    Beckman Ultraviolet, Thermo Electric Chemiluminescence
                                  71

-------
co2
so2
CO
 Beckman Infrared
02     Beckman Paramagnetic

Esso also employed a remote recorder readout of CO, N02 and 02 in the
control room for convenience in observing emission levels during testing.

There were no conveniently located test inserts available for gas sam-
pling at the gas duct entering the air heater.  Esso, therefore, had to
set up a twelve point sampling grid after the air heater.  The flue gas
sampling rate from each point was proportioned to a gas flow previously
determined by velocity traverse.  All gas sample lines were heated until
the particulate filters, then all condensables are removed by a 32F ice
bath.  The gas sample is then blended to one sample per probe location
and pumped under 5 pounds pressure to the sample analytical van.

C-E instrumented Corners #1 and 2 windbox compartments to determine the
amount of overfire air and the air flow to each compartment.  A static
pressure tap was installed in each compartment and the pressure differ-
ential to the furnace measured.

Petroleum coke, Alabama coal  and Midwest coal are normally available at
this plant.  Normally the coals are fired as mixed in the coal pile.  For
the test series Alabama and Midwest coals were supplied directly to the
bunker.  The petroleum coke is burned in a separate Nozzle "C" with coal
firing in surrounding Coal Nozzle B and D to insure stable ignition.

Normal coal fineness as taken before the tests was 72 percent thru the
200 mesh screen.  Coal  fineness was changed to approximately 60 percent
thru the 200 mesh screen on several tests to investigate the possible
effect on NO  emission levels.
            
                                  72

-------
Esso Research obtained pulverizer coal and coke samples from the feeder
belts of each mill on every test.  Typical analysis for the coals and
coke is presented on Sheet 17.

Unit Performance
Boiler operation as reported on Sheet 15 and ISA was based on board in-
strumentation.  The NO , CO, C02 and S02 PPM values represent data as
averaged from Esso data sheets using the appropriate instrument calibra-
tion tables.

Test Emission Data
Overfire Air
The greatest effect on NO  emission levels was obtained by use of over-
                         A
fire air which decreases the amount of air to the firing zone.  Figure
40 presents the NO  emission levels versus percent excess air to the
       ,           A
firing zone for all tests.  Emission levels are reduced from 525 PPM to
approximately 327 PPM in reducing theoretical air from 134 to approxi-
mately 95 percent at 0 tilt.

Excess Air
Unit operating excess air as determined at the air heater inlet had no
significant effect on NO  emission levels (corrected to 0 percent excess
                        A
air when maintaining a constant theoretical air to the firing zone.
Figure 41 shows that with this type of operation the unit operating ex-
cess air level could be varied from 6 percent to 26 percent with essen-
tially constant NO  emission; unit excess air was important, however, in
                  A
keeping CO emissions at low values (Figure 42).

CO Emissions
Figure 42 indicates that CO emissions are a function of percent excess
air at the air heater inlet and also the amount of overfire operation.
The test data indicates that at 15 percent excess air unit operation
and no overfire air the CO emission was 33 PPM which increased to 93 PPM
                                  73

with overfire air (90 to 100 percent theoretical air to burner zone).
In coal firing 15 percent excess air would seem to be the lowest prac-
ticable limit of operation.

Nozzle Tilt
Operating at -30 fuel nozzle tilt increased the NO  emission approxi-
                                                   A
mately 87 PPM over that obtained at 0 tilt.  The limited testing with
plus tilts o-
sion levels.
plus tilts of +15 and +20 produced  no effect on  the  measured  NO   emis-
                                                                A
Effects of Other Operating Variables
The variation of primary/secondary air dampers (Figure 43) unit load and
the pulverized coal fineness had minor effects on NO  emission levels.
This substantiates previous test results and indicates that these opera-
ting variables should continue to be used to control normal boiler op-
eration and should not be considered as NOX controls with coal firing.

Type of Coal
During the test series the following combinations of fuel were fired:

              Fuel                     No. of Tests

   1.  Alabama Coal                          4
   2   Alabama Coal + Coke                  15
   3.  Midwest Coal + Coke                   5

Figure 40 plots all tests and identifies the firing combinations and in-
dicates no change in emission levels with fuel change.

Unit Operation
Superheat-reheat outlet temperature of 538/538C could be maintained at
90 percent MCR horizontal tilt and 95 percent theoretical air to the
burner zone which was the optimum NO  reduction conditions.  The overfire

operation maintains the gas weight thru the unit which results in un-
changed superheat-reheat performance.

No adverse furnace slagging was noted during the short term tests with
low theoretical air to the firing zone.  The three hundred hour, long
term test with approximately 95 percent theoretical air to the firing
zone and 15 percent excess air at air heater inlet was also completed
without excessive furnace slag buildup.

300 Hour Corrosion Probe Test Results
Corrosion probes were installed in the furnace of the test boiler by
inserting them through available viewpoints in the furnace firing zone
as shown on Figure 44.  Prior to installing the probes in the test fur-
nace, the probes were prepared by mild acid pickling, preweighing the
coupons, and screwing them onto the probes along with the necessary
thermocouples.  Each probe was then exposed to the furnace atmosphere
prevailing for the particular type of operation desired for approxi-
mately 300 hours at coupon temperatures of about 468C in order to accel-
erate corrosion.  After exposure, furnace slag was cleaned off and saved
for future analyses, and the coupons were carefully removed from the
probes.  In the laboratory the coupons were cleaned ultrasonically with
fine glass beads to the base metal, and reweighed to determine the
weight loss.

Total weight loss data was converted to corrosion rates on a mils per
year basis, using the combined inner and outer coupon rates, coupon
material density, and exposure time.

Corrosion rates have been determined for 8 coupons installed on 4 probes
(2 coupons/probe), in four different locations on the furnace wall.  The
corrosion data obtained is tabulated on Sheet 16.

Although there is some scatter in the data obtained, Esso concluded "that

no major differences In corrosion rates have been observed for coupons
exposed to  'low NO  ' conditions compared to those subjected to normal
operation."

Esso further concluded that "since corrosion rates were deliberately
accelerated in this study in order to develop  'measurable1 corrosion
rates in a short time period, measured rates, as expected, are much
higher than the normal wastage of actual furnace wall tubes."

Task IX - Application Guidelines
The program outlining the application of the technology developed under
this study to existing and new tangentially coal fired utility boilers
will be presented in the Task IX report and is therefore not discussed
as part of this report.

                       COMPFLOW - WINDBOX
       COMPARTMENT AIR FLOW DISTRIBUTION COMPUTER PROGRAM

INTRODUCTION

A description of COMPAIR, a computer program which calculates the wind-
box assembly air flow distribution, was presented in Reference 1.  The
program has been subsequently found to be deficient; the approach taken
in the calculation of the compartment loss coefficient resulted in op-
erational difficulties in certain cases.  The program was revised to
eliminate this problem.

The revised program, COMPFLOW, is described herein.   The basic assump-
tions and limitations of the calculation method are outlined and dis-
cussed.  Program runs for two tests conducted at Barry #2 are included.

ANALYSIS

Consideration will be initially focused on those cases where the air
flow to each compartment is supplied solely by the windbox.

                                Assumptions:

                                1.   Constant total pressure  at compart-
                                    ment inlet plane, i.e.,  PT  = const.
                                2.   Constant density, i.e., R(I)  = R =
                                    const.

                                3.   Constant static pressure at nozzle
                                    exit plane, i.e., P   = const.
                                                        y

                                4.   Fully turbulent flow, i.e., Head
                                    1  (Velocity) .
Utilizing these assumptions, it follows that
     2 * [ TX
= K(I) * gWf]   = const.
0)
         Where K(I)  = loss coef.  for Compartment "I"
               Q(I)  = volume rate of flow for Compartment "I"
               A(I)  = nozzle exit area of Compartment "I"
                             123

Wl + W2              Wl + W2

     where W(I) = mass rate of flow to Compartment "I"
           Wl   = total windbox air to corner
           W2   = total mill air to corner
           X(I) = fraction of mill air to Compartment "I"

Figure 1 and Equations (6) and (7) constitute the basis of COMPFLOW.

Note that if some other source of air were available to the windbox as-
sembly, Equation (7) would yield the flow distribution with adjustments
in the definitions of W2 and X(I).

Note also that if there is no corner to corner biasing of compartment
dampers, Equation (7) may, to a very good approximation, be regarded
on a furnace/elevation basis.

DISCUSSION

A.  Development of the Method

The method presented herein, of calculating the windbox assembly flow


                              125

distribution, is the result of what is obviously a greatly simplified
treatment; numerous assumptions were made in the development of the
method.  The validity of each of these assumptions will  now be examined.

Assumption (1):  Constant total pressure at the compartment inlet plane.

                 Air issuing from a duct branches to each of the wind-
                 box assemblies; the fluid is moving at a low velocity
                 relative to that at the nozzle exit.  It would be
                 reasonable to assume that the total pressure loss be-
                 tween the supply duct exit and the compartment inlet
                 plane is a negligible fraction of the velocity head
                 at the nozzle exit.  It is all the more realistic to
                 assume, as is the case herein, that the total pressure
                 distribution in the supply duct and the consequent
                 losses along individual streamlines, are such that the
                 total pressure is uniform at the compartment inlet
                 plane.

Assumption (2):  Constant density fluid within the windbox assembly.

                 The reasoning for this assumption is analagous to that
                 set forth in (1); note that while isothermal flow is
                 not implied between the supply duct and the compartment
                 inlet, it is assumed within the windbox assembly.

Assumption (3):  Constant static pressure at the nozzle exit plane.

                 The static pressure of the jets issuing from the wind-
                 box nozzles is equal to the local furnace pressure.
                 The variation in furnace pressure throughout this re-
                 gion should be negligibly small.

Assumption (4):  Fully turbulent flow.

                 This is a valid assumption for the vast majority of
                 cases; unit Reynolds numbers(based on nozzle exit
                 velocity) greater than 10  per foot are typical even
                 for small opening of compartment dampers.
Assumption (5)
The compartment loss coefficient for existing configura-
tions are adequately represented by the formulations
presented herein (i.e. Figure 1 and Equation (6)).

Curves of K versus damper position, as calculated from
Figure 1 and Equation (6), are shown in Figure 4 for
compartment outlet/inlet area ratios (i.e. A(I)/B(I) of
0.534, 0.322 and 0.136; these values cover the range of
our existing compartments.  Results obtained from the
cold-flow model tests of Reference 5, at area ratios
of 0.322 and 0.136, are also shown in this figure; the
                              126

-------
                 test results are seen to be In excellent agreement
                 with the predicted values.  These test results indicate
                 that nozzle tilt, flow rate, firing angle, the presence
                 of turning vanes and probably compartment inlet inter-
                 action, are secondary influences on compartment pressure
                 loss and consequently on compartment flow rate.  These
                 results justify the omission of these factors in the
                 development of the method presented herein.

B.  Previous Calculations

In the previous method of calculating the windbox assembly flow distri-
bution (Reference 1), the compartment loss coefficient was determined from
the equation
                               2
          = KO+KD(I)


          where KD(!) was specified as herein KO evaluated from test
          values of the total secondary air flow and windbox/furnace AP.
          Highly closed damper positions result in a very large value of
          KD, as is seen in Figure 1, and a small error in this parameter
          will result in a large variation in KO.  Program runs with all
          compartment dampers at or near the full open position yielded
          values of KO consistent with the value presented herein, i.e.,

               @ 100% open, Kn0.1, K = K/10035
                                                      .2
               from Equation (6), K/100%^ 1 + 1.7 * []

                                            . 2
               for existing geometries, 0<[g-]  < 0.29


               therefore, with KO^K/IOOX, 1 < KO <1.5

Program runs with one or more compartment dampers highly closed would
sometimes yield values of KO outside this range; in rare cases this
would result in operational  difficulties.

                       Definition of Output

1.  The "AREA WT. FLOW" is the ratio of the compartment free area to
    the total free area of the corner; as such it is a realistic
    approximation of the actual compartment (secondary) flow only when
    all compartment dampers are full open.

2.  The comparment "ACTUAL FLOW" is the ratio of the compartment mass
    flow rate (including mill air if applicable) to the total mass flow
    to the corner (see ANALYSIS, equation (7)).

3.  The "FIRING FUEL COMPARTMENT TOTAL AIR FLOW" is the ratio of the
    total mass flow rate to firing fuel compartments (including mill air
    if applicable) to the total mass flow to the corner.

4.  The "AIR FLOW ABOVE BURNER ZONE" is defined as the percentage of the
    total mass flow rate supplied above the uppermost firing fuel com-
    partment, less 50% of the flow to the compartment immediately above
    it.

5.  % Theoretical Air = (1-  % Air Above Burner Zone)(1QO + % Exce$s A1r)

 is. ABSTRACT The reporf gives results of Phase II of a program to reduce the emission
 of NOx from tangential coal-fired boilers.   Results of Phase I, during which a suit-
 able utility steam generator was selected to be modified for the Phase II studies,
 were presented in final report EPA-650/2-73-005, dated August 1973.  The Phase II
 work included: the design, fabrication,  and delivery of an overfire air system for the
 test unit; the installation of test equipment; planning; and baseline, biased firing and
 overfire air studies for NOx emission control while burning a Kentucky bituminous
 coal type.  These test programs included an evaluation of the effect of variations in
 excess air, unit slagging, load, and overfire air on unit performance and emission
 levels.  The effect of biasing combustion air through various out-of-service fuel
 nozzle elevations was also evaluated.  The effect of biased  firing and overfire air
 operation on waterwall corrosion potential was evaluated during three  30-day baseline
 biased firing, and overfire air corrosion coupon tests.  Unit loading and waterwall
 slag  conditions had minimal effects on  NOx emission levels.   Reductions in excess
 air levels and overfire air operation were found to be effective in reducing NOx
 emission levels.
