SECTION 1
INTRODUCTION
During the week of February 21, 1982, personnel from PEDCo
Environmental conducted an emission sampling program at the
lightweight aggregate facility of Galite Corporation in Rockmart,
Georgia. The purpose of this test program was to provide data to
assess the need for New Source Performance Standards (NSPS) for
selected processes in the lightweight aggregate industry (clay,
shale, and slate) and, if warranted, to develop such limits.
Comprehensive testing was conducted on 1) a coal-fired
rotary kiln (No. 1), whose emissions are controlled by a medium-
energy wet scrubber, and 2) a reciprocating grate clinker cooler,
whose emissions are controlled by a settling chamber.
Particulate concentrations and mass emission rates were
measured at the inlet and outlet of the wet scrubber serving the
kiln exhaust and at the clinker cooler exit stack. U.S. Environ-
mental Protection Agency (EPA) Method 5 was used in these mea-
surements.* Flue gas flow rates, temperature, moisture content,
and composition [oxygen (0_), carbon dioxide [CO-)/ and carbon
monoxide (CO)] were measured in conjunction with the particulate
40 CFR 60, Appendix A, Reference Method 5, July 1, 1981.

tests. EPA Method 6* was used to measure sulfur dioxide (SO-)
concentrations and mass emission rates at the inlet and outlet of
the wet scrubber serving the kiln. Nitrogen oxide (NO ) concen-
X
tration in the flue gas exiting the scrubber was determined by
EPA Method 7.* In addition, the particle size distribution of
particulate matter entering and exiting the kiln scrubber was
determined along with the distribution of particulate exiting the
clinker cooler stack. The volatile organic carbon (VOC) content
of the scrubber exhaust gas was determined by EPA Method 25.*
Visible emission observations were made on each exit stack during
the particulate tests by EPA Method 9.* Additionally, a visible
determination of fugitive dust emissions from specified process
locations was made during each particulate test by EPA Method 9.*
Representative samples of the kiln feed material (slate) and
coal used to fire the kiln were collected during each particulate
test for determination of sulfur content, moisture, density, and
ash content (coal only) . Samples of scrubber water influent, and
effluent, final aggregate product, and captured particulate
(clinker cooler settling chamber) were also collected during each
particulate test for sulfur analyses. In addition, the scrubber
water samples and captured particulate were analyzed for trace
metal content. The pH of the scrubber water and the density of
the final aggregate product were also determined.

SECTION 2
PROCESS OPERATION
Emission tests were conducted on the No. 1 rotary kiln and
clinker cooler exhaust gas streams at Galite Corporation, Rock-
mart, Georgia, from February 22 through 27, 1982. Galite Cor-
poration is a subsidiary of Big River Industries of Baton Rouge,
Louisiana. This plant was selected for emissions testing for the
following reasons: (1) the raw material (slate) at the plant is
one of the three feedstocks used in the production of lightweight
aggregate and (2) the types and arrangement of pollution control
devices on the process equipment appear to be representative of
future plants. The process operations during the tests were mon-
itored by Lalit Banker and Mary Sauer while Frank Clay of EPA
monitored the emission tests.
The Galite plant has two process lines (rotary kilns 1 and
2). The No. 2 kiln was not operating at the time of the test. A
simplified flow diagram of the No. 1 rotary kiln process line
with associated pollution control equipment is presented in
Figure 1. The control equipment tested was the wet scrubber on
the rotary kiln exhaust gas stream and the settling chamber on
the clinker cooler exhaust gas stream.

Process parameters obtained by MRI during the emission tests
are presented in Table 1. The raw material feed rate averaged
about 30 Mg/h (33 tons/h) for the duration of the tests. The
mean coal feed rate in the kiln was approximately 2,090 kg/h
(4,610 Ib/h), while the mean natural gas feed rate was approxi-
mately 31 m /h (1,090 ft3/h). Product density ranged from 577 to
673 kg/m (36 to 42 Ib/ft ) during the emission tests. The above
readings were taken from the beginning to the end of the tests,
and the figures in Table 1 represent averages for the total test
duration.
The settling chamber and wet scrubber, including the pump
supplying water to the wet scrubber, were operating normally dur-
ing the emission tests. The water sprays used to suppress vis-
ible particulate emissions in the process were operating normally
during the emission tests. Fugitive emissions were visible from
the crushing and screening operations, clinker cooler discharge,
and kiln seals.
2.1 PROCESS DESCRIPTION
The slate is mined from a quarry on plant grounds. The
slate is crushed, screened, and stored in piles or enclosed
silos. Belt conveyors transport the crushed slate from the stor-
age silo to the feed box where it is charged to the rotary kiln.
The No. 1 kiln measures 57.9 meters (m) [190 feet (ft)] in
length and 3.7 m (12 ft) in diameter. A dam, which measures 46
centimeters (cm) by 5 cm [18 inches (in.) by 2 in.], is located

Simultaneous particulate test on wet scrubber was voided due to (1) excessive leakage during the post-test leak check for the inlet test
.and (2) loss of sample during recovery for the outlet test.
'Based on 24-h averages, except for tests conducted on 2/27/82.
-------
approximately 4.3 cm (14 ft) from the back end (feed end) of the
kiln. The dam increases the residence time of the raw material
in the kiln and four sets of lifters improve heat exposure. The
kiln rotates at approximately 3.25 revolutions per minute (rpm)
during normal operation. It is designed to process approximately
36 megagrams (Mg) (40 tons) of raw material per hour at capacity.
At the time of the test, approximately 30 Mg (33 tons) of raw
material per hour were processed in the kiln. The raw material
feed is weighed continuously on a scale before it enters the
kiln. There is no continuous monitoring of actual production.
Production figures [in cubic yards (yd )/day of product] are com-
puted from application of a bloating factor equal to 1.05 to the
raw material feed (in tons/day). The bloating factor is computed
by the company and is based on experience with material loss in
the process. Shipping yardage figures are obtained from informa-
tion on the filled volume of the trucks transporting the finished
product and the number of trucks filled each day.
The kiln is fueled primarily by crushed coal. Although the
raw material feed rate is kept constant during normal operation,
minor adjustments to the coal feed rate are made frequently to
control the operating temperature of the kiln. Galite uses coal
with an average heating volume of 2.9 x 10 Joules (J) per kg
[12,500 British thermal units per pound (Btu/lb)], an ash content
of approximately 12 percent, and a sulfur content of approxi-
mately 1 percent. Natural gas with an average heating value of
2.4 x 106 J/kg (1,030 Btu/ft3) is used primarily to fuel the
pilot flame.
2-5
-------
The firing zone (front end) extends about 9 m (30 ft) into
the kiln, and temperatures in this zone range from 1149° to
1177°C (2100° to 2150°F). Mid-kiln temperatures range from 982°
to 1038°C (1800° to 1900°F). Temperatures in the feed end (back
end) of the kiln range from 371° to 454°C (700° to 850°F) and are
monitored continuously. Plant personnel stated that the shutdown
period for the kiln is 48 hours. Bringing the kiln back up to
operating temperature takes 36 to 48 hours. Natural gas is the
primary fuel used for the reheating process.
The raw material slowly heats up as it travels through the
kiln and physically expands (bloats) as volatile organic compo-
nents are driven off. The residence time of the raw material in
the kiln is approximately 45 minutes. Density of the product is
measured hourly by plant personnel who weigh a bucket of known
volume filled with the hot product.
The expanded product, or clinker, is discharged from the
kiln into a clinker cooler. The clinker cooler consists of four
compartments with a reciprocating grate for the circulation of
air through the hot clinker. As the hot clinker is moved across
the grate, four fans force air upward through the grate to cool
the clinker. Approximately 100 percent of the hot exhaust air
from the first compartment and 50 percent from the second com-
partment is recycled to the kiln to conserve combustion heat and
to the coal mill to dry and preheat the coal. The gas stream
recycled to the coal mill passes through a cyclone for dust re-
moval prior to heating the coal. The remaining exhaust air from
2-6
-------
the clinker cooler is ducted through a settling chamber and is
released to the atmosphere through a stack.
Product of acceptable size falls through the reciprocating
grate onto a conveyor belt for transport to the clinker silo for
storage prior to crushing. Oversize material falls from the
grate onto the ground where it is periodically picked up by a
front end loader and transported to a storage pile for supple-
mental cooling and crushing. If the density or the temperature
of the product is too high for the conveyor belt system, the
doors to the conveyor belt are temporarily closed, and the pro-
duct falls from the grate onto the ground.
The product is crushed and screened to three sizes: (1) 100
mesh to 4.8 millimeter (mm) (100 mesh to 3/16 in.), (2) 4.8 to
9.5 mm (3/16 to 3/8 in.), and (3) 9.5 to 19 mm (3/8 to 3/4 in.).
The fines and the mid-size product are used mainly for concrete
blocks while the larger size is used principally for structural
concrete mix. Blends of product sizes are made to consumer
specification. The screened product is stored in enclosed silos.
Galite normally ships approximately 80 percent of its product by
truck and 20 percent by rail. The company employs 50 workers and
operates 365 days per year, 24 hours per day. Galite aims for
actual kiln operation of approximately 80 to 90 percent of
working days.
2.2 AIR POLLUTION CONTROL SYSTEM
The exhaust gases leaving the No. 1 rotary kiln pass through
a settling chamber to remove the heavier particulate matter. The
2-7
-------
waste material is landfilled on-site. The kiln exhaust emissions
are controlled by a medium energy wet scrubber [Fuller/Dracco
Type CAA (Compressed Air Atomizing Scrubber), Size 125-S]. A
336-kilowatt (kW) [450 horsepower (hp)] induced draft (ID) fan,
located between the scrubber and the stack, pulls the exhaust gas
stream from the kiln through the scrubber. The cleaned gas
stream is vented to the atmosphere through a stack approximately
27 m (90 ft) high and 1.8 m (6 ft) in diameter.
Fresh water for the scrubber is pumped from a creek adjacent
to the plant into a storage tank. The water is transferred from
the storage tank to the scrubber by a 20-hp pump with a capacity
of approximately 3,407 liters per minute (liter/min) [900 gallons
per minute (gpm)]. This pump also supplies water to the rest of
the plant. Plant personnel estimate that water enters the scrub-
ber at a rate of about 400 to 450 gpm. The dirty gas flowing
downward through the contact cylinder of the scrubber is con-
tacted countercurrently by a high velocity atomized water spray
introducted near the base of the scrubber. Water is also intro-
duced through two spray bars at the top of the scrubber and one
at the gas inlet to the scrubber. Dust particles are captured by
the liquid droplets and accumulate at the scrubber base. A mist
eliminator is present in the scrubber and was assumed by plant
personnel to be operating during the tests. The scrubber efflu-
ent is pumped to a settling pond at the quarry end of the plant.
The water is pumped from the pond and is discharged to the creek.
2-8
-------
The discharge point is located close to the inlet water pipe for
the scrubber water, and therefore, some mixing of fresh creek
water and recycled plant water occurs. Plant personnel estimate
that the influent scrubber water is typically 90 percent fresh
water. No instrumentation is present at the plant to measure the
scrubber pressure drop, inlet and outlet gas flow rates and tem-
peratures, or inlet and outlet liquid flow rates.
The clinker cooler emissions from the No. 1 kiln process
line are controlled by a baffled settling chamber. The collected
dust is discharged to the conveyor where it is combined with the
product. The clinker cooling air is pulled through the settling
chamber by a 45-kW (60-hp) fan and is exhausted through a stack
approximately 1.2 m (4 ft) in diameter and 12.2 m (40 ft) high.
No instrumentation is available to measure the inlet and outlet
gas flow rates and the temperatures across the chamber.
Water sprays are used to suppress visible particulate emis-
sions from the crushing and screening operations and other mate-
rial handling and transfer points. The flow rates for the water
sprays are not available.
2.3 CONCLUSIONS AND RECOMMENDATIONS
The process and control systems operated normally for the
duration of the tests. The production rate during the test was
kept constant at about 83 percent of the kiln design capacity.

SECTION 3
SUMMARY OF RESULTS
This section details the results of the emission sampling
program. All emission samples and plume observation data were
collected simultaneously from the kiln and clinker cooler sources.
Results are reported separately for each source.
The first set of particulate tests at the kiln exhaust
scrubber were voided due to an excessive post-test leak and loss
of sample during the recovery phase. These data are not included
in this report.
Appendix A contains complete printouts of field data,
results tabulation, and example calculations. Appendices E and C
present field and laboratory data sheets. Appendix D details the
sampling and analytical procedures used during this test program.
Appendix E shows equipment calibration procedures and results.
Appendix F addresses the quality assurance considerations perti-
nent to this test project.
3.1 ROTARY KILN EXHAUST
Particulate and particle size tests were simultaneously
conducted at the scrubber inlet and outlet test locations.
Visible emission observations were performed during the particu-
late testing. Tests for sulfur dioxide were also conducted
3-1
-------
simultaneously at the scrubber inlet and outlet test locations,
and tests for NO and VOC content in the scrubber exhaust gas
X
were performed concurrent with the SO- tests.
Particulate sampling and analytical procedures followed
those described in EPA Method 5 of the Federal Register* except
that an ether-chloroform extraction was performed on the impinger
contents to determine condensible organic and inorganic fractions.
At the scrubber inlet, an instack thimble was placed prior to the
Method 5 filter because of the heavy particulate loading. The
particle size sampling and analytical procedures used at the
scrubber and clinker cooler exhaust test locations followed those
described in the "Procedures Manual for Inhalable Particulate
Sampler Operation," which was recently developed for EPA by
Southern Research Institute (SRI). At the scrubber inlet,
particle size distribution was determined by a Bacho centrifugal
analysis of collected samples from the particulate tests.
Analytical procedures followed those described in ASME Power Test
Code 28-1965. Sampling and analytical procedures for SO»
followed those described in EPA Method 6* except that large;
impingers were used instead of the midget impingers specified in
Method 6. Sampling and analytical procedures for NO followed
X
those described in EPA Method 7.* Visible and fugitive emission
observations were conducted using procedures described in EPA
Method 9* of the Federal Register. EPA Method 25* was used in
determining the VOC content of the exhaust stream.

3.1.1 Flue Gas Conditions and Particulate Emissions
Tables 3-1 and 3-2 summarize the flue gas conditions and
particulate emissions data collected at the scrubber inlet and
outlet test locations. Since particulate emissions are expressed
in pounds per hour and kilograms per hour, volumetric flow rates
are also expressed in actual cubic meters per hour (acmh) and
actual cubic feet per hour (acfh) at stack conditions. Flow
rates corrected to standard conditions [20°C and 760 mmHg (68°F
and 29.92 in.Hg) and zero percent moisture] are expressed as dry
standard cubic meters per hour (dscmh) and dry standard cubic
feet per hour (dscfh). Particulate concentrations are reported
in milligrams per dry standard cubic meter (mg/dscm) and grains
per dry standard cubic foot (gr/dscf). Emission rates are
expressed in kilograms per hour (kg/h) and pounds per hour
(Ib/h). The product of the concentration and the volumetric flow
rate is the mass emission rate. The filterable particulate
fraction represents material collected in the sample probe and on
the filter, both of which were heated to approximately 121°C
(250°F). The condensible organic and inorganic fractions repre-
sent material that condensed out or was trapped in the impinger
section of the sampling train at a temperature of approximately
20°C (68°F) or less.
At the scrubber inlet, the volumetric flow rate averaged
41,900 dscmh (1,479,500 dscfh), the temperature averaged 475°C
(887°F), and the moisture content averaged 6.4 percent. Oxygen
and carbon dioxide contents averaged 13.5 and 6.6 percent,

respectively. The filterable particulate concentration averaged
39,835 mg/dscm (17.4 gr/dscf), and the corresponding mass emis-
sion rate averaged 1676 kg/h (3695 Ib/h). The condensible
organic and inorganic concentrations averaged 17.1 mg/dscm
(0.0075 gr/dscf) and 31.9 mg/dscm (0.0139 gr/dscf), respectively.
The corresponding mass emission rates averaged 0.71 kg/h (1.6

At the scrubber outlet, the volumetric flow rate averaged
84,000 dscmh (2,965,000 dscfh), the temperature averaged 52°C
(126°F), and the moisture content averaged 13.6 percent. Oxygen
and carbon dioxide contents averaged 16.2 and 4.1 percent,
respectively. Because the gas stream was saturated and contained
water droplets, two moisture determinations were made: the first
involved calculations based on the water collected in the sam-
pling trains, and the second involved psychrometric calculations.
In each case, the lower value (saturation at stack temperature)
was used as the correct moisture content in all calculations, as
determined by EPA Method 4.*
Filterable particulate concentration averaged 644 mg/dscm
(0.281 gr/dscf), and the corresponding mass emission rate aver-
aged 54 kg/h (119 Ib/h). The condensible organic and inorganic
concentrations averaged 4.3 mg/dscm (0.0019 gr/dscf) and 17
mg/dscm (0.0074 gr/dscf), respectively. Organic and inorganic
mass emission rates averaged 0.40 kg/h (0.80 Ib/h) and 1.4 kg/h
(3.1 Ib/h).

-------
Measurements were made to determine the degree of turbulent
flow at each test location as detailed in Method 2 of the Federal
Register.* Select traverse points were checked by aligning the
face openings of the pitot tube perpendicular to the stack
cross-sectional plane, designated "0 degree reference." Null
(zero) pitot readings obtained at 0 degree reference indicates an
acceptable flow condition at a given point. A pitot tube angular
notation of ^10 degrees to achieve a null reading is considered
acceptable. Data from the clinker cooler and scrubber inlet test
locations indicated acceptable flow conditions for particulate
testing. At the scrubber outlet test location, the degree of
angular rotation ranged from 0 to 25 degrees with an overall
average of approximately 13 degrees. Typical velocity profiles
from this source are presented in Figure 3-1 (east traverse) and
Figure 3-2 (north traverse). Turbulent flow conditions of this
type would tend to bias the velocity measurements high, thus
introducing a positive bias in the calculated pollutant mass
emission rates from this source. This conclusion is substanti-
ated by a comparison of scrubber inlet and outlet flow rates on a
standard basis and corrected for air inleakage (including the
cold air bleedin). The measured scrubber outlet flows averaged
approximately 20 percent higher than the corrected inlet flow
rates.
One other source condition that should be addressed is the
effect of scrubber water reentrainment. The outlet gas stream

was saturated as previously mentioned and a heavy plume water
fallout was observed throughout the test period. This fallout
resulted in heavy spotting of clothes and sample equipment. The
average ratio of probe catch to filter catch was 1227 mg to 126
mg. The entrained water droplets laden with particulate matter
were collected in the sample probe, subsequently dried by the
probe heat, and recovered and measured as filterable particulate.
3.1.2 Particle Size Distribution
Three samples were collected at the scrubber inlet and eight
samples at the outlet test sites. Data obtained from the partic-
ulate test runs were combined with sampling data to obtain
average flow rates, moisture content, and gas composition.
At the scrubber inlet, particle size distribution was
determined by a Bacho centrifugal analysis of collected samples
from the particulate tests. The Bacho analyzer utilizes the
centrifugal separation technique to segregate the particulcite
into eight different size ranges. Figure 3-3 presents the
average distribution curve for the three samples collected at the
scrubber inlet. Individual data points for each test were
plotted manually. The results of the average distribution curve
show that the size of the particulate emissions was fairly
consistent during the three sampling runs. The data point
distribution for these runs indicates that 50 percent of the
particulate by weight was less than 13.5 ym in diameter.

Figure 3-3. Particle size distribution - scrubber inlet.
-------
An Andersen cascade impactor was used to collect eight
particle size samples at the scrubber outlet test site. Sample
Nos. SOPS-3, 7, and 9 were considered nonrepresentative due to an
overloading of individual impactor stages; therefore, they are
not graphically presented.
Sampling and analytical prcedures followed those described
in the "Procedures Manual for Inhalable Particulate Sampler
Operation," which was developed by Southern Research Institute
for EPA. Individual and average particle distribution curves
were determined by use of a computer program detailed in the
CIDRS Manual. Each specific program is briefly described here.
The CIDRS Manual can provide details if described.
MPPROG - The basic program calculated stage D,_0 cut-points
and cumulative distributions by two slightly different
methods for each sampling run. The table of output, which
was calculated by Lung Dynamics, assumed a particle density
of 1 g/cm , calculated specific Cunningham correction
factors, and yielded aerodynamic diameters. The next table,
identified as Mercer, assumed both a unit particle density
and a unit Cunningham factor to yield aerodynamic impaction
diameters. Results in both tables were determined by
reducing data according to the D,-n method, which assumed a
stage collection efficiency of 50 percent, as opposed to the
Picknett method, which required stage efficiency curves.
All particle size results discussed in this report were
based on aerodynamic diameters unless stated otherwise.
Example calculations and additional data were included in
the output.
SPLIN 1 - For each sample run, a best-fit curve was calcu-
lated for size ranges, including real data, and extrapolated
to the maximum particle diameter selected. Coefficients
were stored for later use. This program has no tabular
output.
3-12
-------
STATIS - This program averaged the curves calculated in
SPLIN 1 for a minimum of three sampling runs, removed
outliers according to the upper 5 percent significance level
procedure in the QA Handbook,* and calculated results for
cumulative and differential distributions with 50 percent
confidence intervals. All output was tabular, and curves
were manually plotted with extrapolated portions indicated
by dash lines. Averages for less than three runs were
calculated through duplication of data sets, but confidence
intervals were invalid.
Figure 3-4 presents the average particle size distribution
curve for the five acceptable samples collected at the scrubber
outlet. Figures 3-5 through 3-9 present the individual particle
size distribution curves for each of the five sampling runs. All
particle size results are based on aerodynamic diameters and unit
density (1 g/cm ).
The results of the particle size runs show that the majority
of particulate was collected in the precutter of the impactor and
accounted for about 60 percent of the total filterable particu-
late emissions. The majority of the remaining particulate
collected in the impactor was between 0.4 and 2.5 ym, which
accounted for about 20 percent of the total filterable particu-
late collected by the impactor.
3.1.3 Sulfur Dioxide
Table 3-3 presents a summary of results for SO- tests
conducted simultaneously before and after the wet scrubber.
Concentrations are reported in parts per million by volume (ppm),
milligrams per dry standard cubic meter (mg/dscm), and pounds per

reported in kilograms per hour and pounds per hour. The inlet

ulate test run (1,479,534 dscfh). The outlet mass emission rates
were calculated in a similar manner using the average measured
flow rate from the outlet particulate tests (2,964,856 dscfh).
Analyses were conducted on site by EPA Method 6.*
Sulfur dioxide concentrations at the inlet to the wet
scrubber averaged 5620 mg/dscm (2133 ppm, 35.1 x 10 Ib/dscf),
and the corresponding average mass emission rate was 235 kg/h
(518 Ib/h). Flue gas temperature averaged 523°C (975°F), and
oxygen content averaged 12.1 percent.
Sulfur dioxide concentrations at the scrubber exit stack
averaged 2317 mg/dscm. (881 ppm, 14.5 x 10 Ib/dscf), and the
corresponding average mass emission rate was 194.5 kg/h (429
Ib/h). Flue gas temperature averaged 51°C (123°F), and oxygen
content averaged 15.8 percent.
3.1.4 Nitrogen Oxides
Table 3-4 summarizes data on emissions of nitrogen oxides.
Three tests, each consisting of four grab samples collected at
15-minute intervals, were conducted at the kiln exhaust scrubber
outlet. Concentrations are reported in milligrams per dry
standard cubic meter, parts per million by volume, and pounds per
dry standard cubic foot. Emission rates, reported in kilograms
per hour and pounds per hour, were calculated from the average
flue gas flow rate measured during the particulate test runs and
corrected to standard conditions (2,964,856 dscfh).

3.1.5 Hydrocarbon Emissions From the Kiln Scrubber Outlet
Hydrocarbon emissions from the scrubber outlet at Kiln No. 1
were sampled by use of the procedures of EPA Method 25* in order
to determine total gaseous nonmethane organics (TGNMO). Four
1-hour samples were collected at the scrubber outlet. Test No.
SO-VC-1 was voided due to a plug in the sampling probe. Results
of the Method 25 sampling are presented in Table 3-5. In the
Method 25 analytical procedures, all nonmethane organics are
oxidized to carbon dioxide and reduced to methane before measure-
ment with a flame ionization detector (FID). Therefore, organic
concentrations are expressed in ppm as methane and emission rates
were calculated based on the molecular weight of methane (16
g/g-mole).
The nonmethane organic concentration in the outlet stack
varied from 60 to 141 ppm with an average value of 90 ppm as
methane. The average emission rate of nonmethane organic com-
pounds was 5.4 kg/h (11.1 Ib/h) as methane.
3.1.6 Visible Emissions
Each particulate test included a survey of visible emissions
at the kiln scrubber outlet. Visible emissions were read in
6-minute sets throughout each particulate test. Table 3-6
summarizes the findings. For each test, opacities ranged from 0
to 5 percent.

3.2 CLINKER COOLER EXHAUST
Particulate emissions and particle size distribution tests
were performed at the clinker cooler exhaust stack. Visible
emissions were observed at the outlet stack during each particu-
late test.
Particulate sampling and analytical procedures followed EPA
Method 5*, except that an ether-chloroform extraction was per-
formed on the impinger contents to determine condensible organic
and inorganic content. Particle size sampling and analytical
procedures followed those described in the "Procedures Manual for
Inhalable Particulate Sampler Operation," which was recently
developed for EPA by Southern Research Institute. Visible
emission observations were made according to procedures described
in EPA Method 9.* Concentration and mass emission rate data are
expressed in units identical to those used in Section 3.1 of this
report.
3.2.1 Flue Gas Conditions and Particulate Emissions
Summaries of the measured flue gas and particulate emission
data from the clinker cooler exhaust are presented in Tables 3-7
and 3-8.
The filterable particulate data reported in Table 3-8
represent matter collected in the sampling probe and on the
filter, both of which were heated to approximately 121°C (250°F).
The condensible organic and inorganic fractions represent
*40 CFR 60, Appendix A, Reference Methods 5 and 9, July 1, 1981.

The volumetric flow rate averaged 50,500 dscmh (1,783,000
dscfh), the temperature averaged 69°C (156°F), and the moisture
content averaged less than 1 percent. The oxygen and carbon
dioxide contents averaged 20.5 and 0 percent, respectively.
Filterable particulate concentration averaged 128.5 mg/dscm
(0.056 gr/dscf) with a corresponding average mass emission rate
of 6.4 kg/h (14.1 Ib/h). The organic and inorganic concentra-
tions averaged 2.34 mg/dscm (0.0010 gr/dscf) and 3.92 mg/dscm

averaged 0.12 kg/h (0.26 Ib/h) and 0.19 kg/h (0.42 Ib/h).
3.2.2 Particle Size Distribution
A total of eight particle size samples were collected from
the clinker cooler outlet during the particulate test runs,. An
Andersen cascade impactor was used for these tests. Section
3.1.2 describes the sampling and analytical procedures and the
data reduction techniques used, respectively. Run Nos. CCPS-2,
3, and 6 were considered nonrepresentative and are not graphi-
cally presented.
Figure 3-10 presents the average particle size distribution
curve for the five acceptable runs conducted at the clinker
cooler outlet test site. Figures 3-11 through 3-15 present the
individual particle size distribution curves for each of the five

sampling runs. All particle size results are based on aerody-
namics diameters and unit density (1 g/cc).
The average particle size distribution for this source shows
that the particulate emissions are fairly evenly distributed by
size and that about 44 percent of the particles are less than 10
ym in diameter. The individual particle size distribution curves
compared closely, and the maximum deviation between the five runs
at two separate cutpoints were 4 percent at 6 ym and 4.5 percent
at 1 ym. This indicates that the size of the particulate emis-
sions were fairly consistent during the testing period.
3.2.3 Clinker Cooler Visible Emissions
Visible emissions were surveyed at the clinker cooler outlet
during each particulate test. Visible emissions were read in
6-minute sets throughout each test. Table 3-9 summarizes the
visible emissions data.
3.3 FUGITIVE EMISSIONS
Fugitive emissions were surveyed during each particulate
test using procedures described in EPA Method 9.* Separate
surveys were performed at the following locations: raw material
crushing, final product crushing and screening, and kiln seals
(charge and product). Table 3-10 summarizes the results of the
fugitive emission survey.
3.4 PROCESS SAMPLES
Representative samples of the kiln feed material (slate) and
coal used to fire the kiln were collected during each particulate

test for determination of sulfur content, moisture, density, and
ash content (coal only). Samples of scrubber water influent and
effluent and final aggregate product were also collected during
each particulate test for sulfur analysis. In addition, the
scrubber water samples and captured particulate (clinker cooler)
were analyzed for trace metal content. The pH of the scrubber
water and the density of the final aggregate product were also
determined. Table 3-11 summarizes the analytical data.
The analytical data on the raw slate showed an average
sulfur content of 0.69 percent, an average moisture content of
1.04 percent, and an average density of 2.73 g/cm . The sulfur
content of the final product averaged 0.37 percent with an
average density of 2.61 g/cm . The coal data showed on average
sulfur content of 1.47 percent and an average ash content of
14.26 percent. Moisture content averaged 5.2 percent. The
average sulfate concentration of the scrubber influent and
effluent was 27 and 990 mg/liter, respectively. Composite
samples of scrubber influent showed a pH of 7.0, and the effluent
showed a pH of 5.69. Table 3-12 summarizes trace metal data from
the scrubber effluent and captured particulate samples from the
clinker cooler settling chamber.

SECTION 4
SAMPLING LOCATIONS AND TEST METHODS
Figure 4-1 presents a simplified process flow sheet depict-
ing the sampling locations and type of testing conducted at each
site.
The following subsections describe the sampling sites for
particulates, sulfur dioxide, nitrogen oxide, VOC, and particle
size distribution testing.
4.1 SCRUBBER INLET
Particulates, sulfur dioxide, and particle size distribution
were measured at the inlet to the wet scrubber as shown in Figure
4-2. Two sampling ports, 90 degrees off-center, were located 2.6
duct diameters (dd) downstream and 0.6 dd upstream from the
nearest flow disturbances in the 1.4-m (4.6-ft) I.D. round duct.
Due to extreme heat and inaccessibility, only one of these ports
was used. Twenty-four traverse points (each point was sampled
twice) were used to traverse the cross-sectional area of the duct
for the particulate tests. Each point was sampled, for 2.5
minutes, which yielded a total test time of 120 minutes. Constant-
rate sampling techniques were used to sample sulfur dioxide;
emissions by placing the probe tip near the center of the duct.

4.2 SCRUBBER OUTLET
Particulates, sulfur dioxide, nitrogen oxide, particle size
distribution, and VOC content were measured at the wet scrubber
outlet, as shown in Figure 4-3. Two sampling ports, 90 degrees
off-center, were located 2.5 dd downstream and 4.0 dd upstream
from the nearest flow disturbances in the 1.86-m (6.1-ft) I.D.
round stack. Forty-eight traverse points, 24 per port, were used
to traverse the cross-sectional area of the stack for the partic-
ulate test runs. Each point was sampled for 2.5 minutes, which
yielded a total test time of 120 minutes. Sulfur dioxide,
nitrogen oxide, and VOC sampling were conducted by use of con-
stant-rate sampling techniques that placed the respective probe
tips near the center of the stack. An Andersen in-stack impactor
was used to collect particle size samples at single sampling
points were representative of the average velocity of the stack.
4.3 CLINKER COOLER EXHAUST
Particulate concentrations and particle size distribution
were measured at the clinker cooler exit stack, as shown in
Figure 4-4. Two sampling ports, 90 degrees off-center, were
located 3.0 dd downstream and 2.4 dd upstream from the nearest
flow disturbances in the 1.5-m (5.0-ft) I.D. round stack.

late test runs. Each point was sampled for 2.5 minutes, which
yielded a total test time of 120 minutes. An Andersen in-stack
impactor was used to collect particle size samples at single
sampling points that were representative of the average stack
velocity. The testing and analytical procedures used are de-
scribed briefly below.
4.4 VELOCITY AND GAS TEMPERATURE
A Type S pitot tube and an inclined draft gauge manometer
were used to measure the gas velocity. Velocities were measured
at each sampling point across the duct to determine an average
value. Measurements were made according to the procedures
outlined in Method 2 of the Federal Register.* The temperature
was also measured at each sampling point by use of thermocouple
and digital readout.
4.5 MOLECULAR WEIGHT
Flue gas composition was determined by using procedures
described in Method 3 of the Federal Register.* A bag sample was
collected during each particulate test and during each set of
sulfur dioxide and nitrogen oxide tests. The bag contents were
analyzed by use of an Orsat gas analyzer.
4.6 PARTICULATES
Particulate grain loading was measured at each test location
according to Method 5, as described in the Federal Register.*
All tests were conducted isokinetically by traversing the cross-

sectional area of the stack and regulating the sampling flow rate
relative to the flue gas flow rate as measured by the pitot tube
attached to the sampling probe. In each test, a sampling train
was used consisting of a heated, glass-lined probe, a heated
87-mm (3-in.) diameter glass fiber filter (Reeve Angel 934 AH),
and a series of Greenburg-Smith impingers. A heated quartz probe
was used on the scrubber inlet sampling train due to the high
flue gas temperatures at this location. In addition, an alundum
thimble and cyclone were placed prior to the heated filter
because of heavy particulate loading. The nozzle, probe, and
filter holder were rinsed with acetone at the end of each test.
The acetone rinse and the particulate caught on the filter media
were dried at room temperature (105°C for scrubber outlet sam-
ples) , desiccated to a constant weight, and weighed on an analyt-
ical balance. Total filterable particulate matter was determined
by adding these two values. The contents of the impinger section
of the sampling train were recovered and analyzed for organic and
inorganic content by ether-chloroform extraction.
4.7 SULFUR DIOXIDE
The test procedure used was as described in Method 6 of the
Federal Register* except the midget impingers were replaced with
a series of Greenburg-Smith impingers. A heated glass-lined
probe preceded the series of impingers. A plug of glass wool was
placed in the tip of the probe and in the connecting glassware

-------
between the first and second impingers. A heated quartz glass
probe was used on the scrubber inlet sampling train, and an
alundum thimble and cyclone-filter assembly were placed prior to
the impingers due to the heavy particulate loading at this
location. Each test consisted of two 20-minute runs. Each
sampling train was purged with ambient air for 15 minutes after
the completion of each test. The contents of the second and
third impingers (3% hydrogen peroxide) were measured and analyzed
on site for sulfates by use of the barium-thorin titration
method.
4.8 NITROGEN OXIDE
Sampling and analytical procedures were those described in
EPA Method 7 of the Federal Register.* Three tests, each con-
sisting of four grab samples taken at approximately 15-minute
intervals, were conducted at the scrubber exit stack. The
samples were shipped to the laboratory for analysis.
4.9 PARTICLE SIZE DISTRIBUTION
Particle size samples from the scrubber and clinker cooler
exit stacks were obtained by use of an Andersen 2000 Mark III
source cascade impactor. This in-stack, multistage cascade:
impactor has a total of eight stages. Particle size cutoffs
range from 0.5 to 15 ym and are followed by a backup filter-
stage. Substrates for the Andersen impactor were 64-mm glass
fiber filters.** A constant sampling rate was maintained through-

out the test period. The rates were set for isokinetic sampling
as long as the rate did not exceed the recommended flow rate for
the impactor (0.70 acfm).
Eight impactor runs were made at each sampling site.
Sampling point locations for each stack were as shown in Figure
4-5. At least one impactor run was made at each sampling point.
Sampling procedures were those recommended in the "Procedures
Manual for Inhalable Particulate Sampler Operation," which was
recently developed for EPA by the Southern Research Institute.
Particle size analyses were conducted on the scrubber inlet
particulate samples by use of a Bahco centrifugal classifier
that separated the particulate into eight different size ranges.
4.10 HYDROCARBON EMISSIONS
\
EPA Method 25* was used in the sampling and analysis of
hydrocarbon emissions in order to determine total gaseous non-
methane organics. Gas from the stack was drawn through a dry-ice
condensate trap in order to collect the sample in an evacuated
sampling tank. Sampling was conducted at a single point in the
stack and a constant sampling rate was maintained between 80 and
90 (ml/min). Both the sampling tank and condensate trap were
analyzed to determine the nonmethane organic content of the
exhaust gas.
The tank fraction was analyzed by injecting the sample into
an analyzer. The analyzer separated the nonmethane organics from

CO, CO-, and CH., oxidized the components to CO- and reduced the
C02 to methane for measurement with a flame ionization detector
(FID).
Condensate was recovered by heating the trap and probe line
to 650°C (1200°F), converting the contents to carbon dioxide with
a catalytic oxidizer, and collecting the C0~ in an intermediate
collection tank. The intermediate tank was analyzed by injecting
the contents into the analyzer, where the CO- was reduced to
methane and measured with the FID. The total gaseous nonmethane
organic content was determined by summing the results of the trap
and tank analyses.
4.11 PROCESS SAMPLES
Samples of the coal and slate fed to the kiln were collected
at approximately 30-minute intervals during particulate sampling.
Coal samples were collected from the coal bunker before they
entered the pulverizer. Slate samples were collected from the
kiln feed conveyor belt. Coal samples were analyzed for sulfur
content, moisture content, and percent ash. Slate samples were
analyzed for sulfur content, density, and moisture content.
Samples of the influent and effluent from the kiln wet
scrubber and clinker cooler settling chamber were collected and
analyzed for sulfate content and pH (scrubber water only).
An analytical screening for trace elements was performed on
the scrubber effluent and captured particulate samples.

4.12 VISIBLE AND FUGITIVE EMISSIONS
Visible and fugitive emission observations were performed by
use of procedures described in EPA Method 9.* Certified vissible
emission readers were utilized for each task.

SECTION 5
QUALITY ASSURANCE
Because the end product of testing is to produce representa-
tive emission results, quality assurance is one of the main
facets of stack sampling. Quality assurance guidelines provide
the detailed procedures and actions necessary for defining and
producing acceptable data. Four such documents were used in this
test program to ensure the collection of acceptable data and to
provide a definition of unacceptable data. The following docu-
ments comprise the source-specific test plan prepared by PEDCo
and reviewed by the Emission Measurement Branch: the EPA Quality
Assurance Handbook Volume III, EPA-600/4-77-027; the draft PEDCo
Environmental Emission Test Quality Assurance Plan; and the: PEDCo
Environmental Laboratory Quality Assurance Plan. The last two,
which are PEDCo's general guideline manuals, define the company's
standard operating procedures and are followed by the emission
testing groups and the laboratory groups.
Appendix F provides more detail on the quality assurance
procedures, such as QA objective; data reduction; quality control
checks; performance and system audits; preventive maintenance;
precision, accuracy, and completeness; corrective action; and
quality assurance reports to management.
5-1
-------
Relative to this specific test program, the following steps
are taken to ensure that the testing and analytical procedures
will produce quality data.
0 Calibration of field sampling equipment. (Appendix E
describes calibration guidelines in more detail.)
0 Checks of train configuration and calculations.
0 Onsite quality assurance checks such as sampling train,
pitot tube, and Orsat line leak checks, and quality
assurance checks of all test equipment prior to use.
0 Use of designated analytical equipment and sampling
reagents.
Table 5-1 lists the sampling equipment used for particulate,
SO- and NO testing as well as the calibration guidelines and
^ J*L
limits. In addition to the pre- and post-test calibrations,, a
field audit was performed on the meter boxes used for particulate
and S0_ sampling. PEDCo constructed critical orifices for use in
this audit. Figures 5-1 through 5-3 show an example audit run
for each dry gas meter used for particulate and SO- testing..
As a check on the reliability of the method used to analyze
the filters for the particulate and particle size tests, sets of
filters that had been preweighed in the lab were resubmitted for
replicate analysis. Table 5-2 summarizes the results of a blank
filter and reagent analysis.
Audit solutions prepared by the EPA were used to check the
analytical procedures and reagents for S09 and NO sampling
^ ji
analysis. Tables 5-3 and 5-4 present the results of these
analytical audits. The audit tests show that the analytical
techniques were good.

The quality assurance procedures specified in Method 25
include oxidation and reduction catalyst checks, complete cali-
bration of the NMO analyzer, use of proper materials of construc-
tion for sampling tanks and traps (316 stainless steel), and
checks to determine the blank values for the analyzer and trap
conditioning apparatus carrier gases. In addition, PEDCo has
found it necessary to use the following procedures to check and
prepare sampling equipment before testing. Prior to each test,
all condensate traps are checked for cleanliness by use of the
trap conditioning apparatus. Traps are heated to 650°C (1200°F)
with carrier gas passing through the trap, oxidizer, and GC
sampling loop. The sampling loop contents are then injected to
the NMO analyzer to determine the level of contaminant remaining
in the trap. This process is repeated until an acceptable blank
value is obtained. Typical blank values for traps range from 5
to 10 ppm.
Gas sampling tanks are cleaned by evacuating the tanks and
filling them with nitrogen. This procedure is repeated until an
analysis of the tank on the Method 25 analyzer demonstrates that
the tank contains no contaminants from previous sampling jobs.
All tanks to be used in a testing program are checked in this
manner before shipment to the sampling site. Appendix C contains
pretest equipment blank data and laboratory results. This
appendix also contains chromatograms showing the blank checks for
the traps and tanks used in this test.

The sampling equipment, reagents, and analytical procedures
for this test series were in compliance with all necessary
guidelines set forth for accurate test results as described in
Volume III of the Quality Assurance Handbook.*

SECTION 6
DISCUSSION OF RESULTS
Overall, the sampling program was executed as planned and,
with the exception of the scrubber inlet test location, no major
problems occurred with either test equipment or sampling activi-
ties. As mentioned previously, only one sampling port was used
for particulate sampling at the scrubber inlet because of extreme
heat and inaccessibility. With increasing distance from down-
stream and upstream disturbances, the effect on the results of
sampling in only one plane would be less significant. Since this
location met only the minimum requirements set forth in EPA
Method 1, however, the particulate data could be biased high; the
magnitude of which is unknown.
As discussed in Section 3 of this report, particulate mass
emission rates at the scrubber outlet are probably biased high
due to the cyclonic flow condition encountered. Since mass;
emission rate data are calculated on the basis of volumetric
flow, the mass emission rate data for each measured pollutant
should be considered on a qualitative basis only.
Both the filter and rinse fractions from this source were
heated to 105°C (221°F) as analytically allowed in the Federal
6-1
-------
Re'gister. * In addition, both fractions were heated to 160°C
(320°F) to preclude sample bias resulting from sulfuric acid mist
retention. No significnt sample weight loss resulted from the
sequential heating.
Table 6-1 summarizes particulate removal efficiency and
scrubber pressure drop data. Despite the fact that the scrubber
lacked an effective mist elimination device system, the particu-
late removal efficiency averaged greater than 98 percent with an
average scrubber pressure drop of 14 inches of water. The
pressure drop data is probably biased high due to frequent
plugging of the inlet sample line. With an effective mist
eliminator, particulate concentration would probably be signifi-
cantly reduced.
The measured particulate emissions from the clinker cooler
appear to be representative based on between-test data reproduci-
bility and comparisons with plume observation and particle size
data from this source.
