                              1.0  INTRODUCTION

     This report presents estimates of the costs and cost effectiveness
associated with controlling nitrogen oxides (NO ) emissions from small
                                               A
boilers.  The report was prepared as part of the project to develop new
source performance standards (NSPS) for small  boilers under Section 111 of
the Clean Air Act.  Small boilers are defined as industrial-commercial -
institutional boilers having heat input capacities of 29 MW (100 million
Btu/hour) or less.  A discussion of available NO  emissions data is
presented in the report entitled, "Overview of the Regulatory Baseline,
Technical Basis, and Alternative Control Levels for Nitrogen Oxides (NO )
                                                     1
Emission Standards for Small Steam Generating Units".
     As discussed in Reference 1, it is not possible to establish
uncontrolled or controlled NO  emission levels for small boilers.  However,
in order to develop estimates of the potential cost and cost effectiveness
                                                 «
of NO  control for small boilers, it was assumed that low excess air (LEA)
     rt
technology could reduce NO  emissions from uncontrolled levels by
                          A
20 percent.  Furthermore, it was assumed that baseline (i.e.,  uncontrolled)
emissions could be approximated as the midpoint of the range of uncontrolled
NO  emissions data for each fuel/boiler type combination.  For this reason,
however, the emission reduction estimates and corresponding cost and cost
effectiveness values .can only be viewed as rough approximations and are of
                              2
use for example purposes only.

-------
                                2.0  SUMMARY

     Capital, operation and maintenance (O&M), and annual 1 zed costs were
estimated for model boilers firing natural gas, distillate oil, residual
oil, and coal.  Boilers with a range of heat input capacities were examined.
Costs were determined for both uncontrolled model boilers and model boilers
equipped with LEA for NO  control.  Rough approximations of baseline (i.e.,
                        ^
uncontrolled) and controlled (LEA) NOX emissions were used to estimate the
cost effectiveness of applying NO  controls to small boilers.
     The results of the analysis are presented in Tables 2 through 21.
These tables show similar trends in costs and cost effectiveness for each
fuel type.  The difference in capital costs between baseline and
N0x-controlled boilers decreases with increasing boiler size.  This can be
attributed to the economies of scale associated with LEA application and its
associated compliance requirements.  The difference in annualized costs
decreases with increasing boiler size and capacity factor.  This trend
results from the increased boiler efficiencies provided by operating with
LEA, which translate into fuel savings.  These fuel savings act to offset
the additional LEA costs for spare parts, maintenance, and annualized
capital costs.
     For boilers subject to continuous compliance and ranging in size from
2.9 to 29 MW (10 to 100 million Btu/hour) and in capacity factor from 0.26
to 0.55, the cost effectiveness of LEA ranges from:

     o    natural gas (priced for the industrial sector) - $314,000 to
          $3,110/Mg ($285,000 to $2,820/ton);

     o    natural gas (priced for the commercial sector) - $314,000 to
          $2,440/Mg ($285,000 to $l,850/ton);

     o    distillate oil - $156,000 to $2,440/Mg ($141,000 to $2,220/ton);

     o    residual oil  - $104,000 to $l,610/Mg ($94,000 to $l,460/ton); and
     o    coal - $107,000 to $2,350/Mg ($97,000  to $2,130/ton).

-------
     Requiring excess emission reporting rather than continuous compliance
results in lower cost effectiveness values.   For boilers ranging from 2.9 to
29 MW (10 to 100 million Btu/hour)  in size and in capacity factor from 0.26
to 0.55, the cost effectiveness of LEA ranges from:

     o    natural gas (priced for the industrial sector) - $225,000 to
          $l,040/Mg ($205,000 to $940/ton);

     o    natural gas (priced for the commercial sector) - $225,000 to $0/Mg
          ($205,000 to $0/ton);

     o    distillate oil - $112,000 to (-$305)/Mg [$102,000 to (-$277)/ton];

     o    residual oil - $75,000 to $576/Mg ($68,000 to $522/ton); and

     o    coal - $78,100 to $l,520/Mg ($70,900 to $l,380/ton).

-------
                    3.0  MODEL BOILER COSTING METHODOLOGY

     This model boiler cost analysis estimates capital, O&M, and annualized
costs using the methodology discussed in Reference 3.  The selection of the
model boiler types and sizes used in this analysis is discussed in
Reference 4.  All costs are presented in June 1985 dollars.  Capital and O&M
costs were updated from other time bases using the Chemical Engineering (CE)
plant cost and Bureau of Labor Statistics (BLS) producer price indices,
respectively.  The total cost for each model system includes the costs of
the boiler, fuel, and add-on NO  control equipment, where applicable.
                               A
     Nitrogen oxides control for all fuel/boiler types is based on the
application of LEA combustion modification.  A description of LEA technology
is provided in Reference 1.  The additional equipment and modifications
required for LEA control are an oxygen trim system (comprising an oxygen
analyzer and air flow regulators) and windbox modifications (for
multi-burner boilers).   These account for the increased capital costs
required for installing LEA on an uncontrolled boiler.
     Annual O&M costs increase with the application of LEA due to associated
costs for spare parts, maintenance labor, and maintenance materials.
However, these cost increases are offset, in part, by lower fuel
requirements for LEA-controlled boilers compared to uncontrolled boilers
because of the higher boiler efficiencies associated with LEA operation.
Lower fuel requirements translate to lower annual fuel costs.
     The fuel prices used in this analysis are projected delivered fuel
prices in EPA Region V for the time period from 1992 to 2007.  These prices,
presented in Table 1, have been 1 eve!ized over this period and are expressed
in June 1985 dollars. '   Region V fuel prices were used for illustrative
purposes.  Similar cost results are expected for other EPA regions.
     Two sets of natural gas price projections are used in this analysis
corresponding to boilers operating in the industrial and commercial natural
gas market sectors.  Projected prices for coal, residual oil, and distillate
oil, on the other hand, are not expected to vary significantly between these
sectors.  Hence, only one set of price projections is used for these boiler
fuels.

-------
     The two boiler compliance options  examined  in  this  memorandum are:
(1) continuous compliance,  including  Appendix  F  quality  assurance
procedures; and (2) excess  emission reporting  requirements.   Continuous
compliance increases capital  costs by $10,000  over  excess emission
reporting, due primarily to the development  of a required quality control
plan.  Annual O&M costs are $17,000 greater  for  continuous compliance than
for excess emission reporting.

-------
                   4.0  MODEL BOILER COST ANALYSIS RESULTS

4.1  NATURAL GAS, INDUSTRIAL FUEL PRICE

     Tables 2 and 3 present the costs of both uncontrolled and LEA-equipped
model boilers operating at capacity factors of 0.26 and 0.55, respectively.
Capital costs for boilers equipped with LEA are about 25 percent higher than
baseline costs at the 2.9 MW (10 million Btu/hour) size.  This capital cost
increase drops to about 5 percent at the 29 MW (100 million Btu/hour) size.
This decrease is due to the economies of scale associated with LEA
application (and compliance requirements) and is observed for each fuel type
examined.
     For the 0.26 capacity factor, applying LEA increases annualized costs
by roughly 16 percent over baseline costs at the 2.9 MW (10 million
Btu/hour) boiler size and by 2 percent at the 29 MW (100 million Btu/hour)
boiler size.  This decline in the cost increase associated with the use of
LEA is primarily due to the increased fuel savings resulting from LEA use in
larger boiler sizes.  As discussed in Section 3.0, the application of
LEA control results in higher boiler efficiencies and, hence, lower annual
fuel costs than baseline boilers.  As boiler size and capacity factor
increase, the magnitude of this fuel cost savings increases and acts to
offset the additional LEA costs for spare parts, maintenance, and annualized
capital costs.  These trends are observed for each fuel type examined.
     fables 4 and 5 present the annualized costs for natural gas-fired model
boilers at capacity factors of 0.26 and 0.55, respectively.  The cost
effectiveness of LEA control is also presented.  Cost effectiveness results
are provided for both continuous compliance and excess emission reporting
requirements.
     The average cost effectiveness values for LEA control decrease as the
boiler size increases for both capacity factors.  The values range from
$314,000/Mg ($285,000/ton) for continuous compliance at the 2.9 MW
(10 million Btu/hour) boiler size and 0.26 capacity factor to $3,110/Mg
($2,820/ton) at the 29 MW (100 million Btu/hour) boiler size and 0.55

-------
capacity factor.   The decrease in  cost effectiveness is due primarily to
three factors:

     (1)  fuel savings increase with increasing boiler size and capacity
          factor, thus reducing incremental  costs  for control;

     (2)  capital costs for LEA equipment and NOX  monitors are distributed
          over larger annual NO  reductions  as boiler size and capacity
                               A
          factor increase, due to  economies  of scale; and

     (3)  estimated emission reductions are  greater on a heat input basis
          for larger boiler sizes  than for small sizes.  This is because
          uncontrolled NO  emissions generally increase with boiler size
                         ^
          for package boilers due  to higher  characteristic heat release
          rates.  Since a constant 20 percent NOX  reduction has been
          assumed, the magnitude of this NO   reduction, on a heat input
          basis, increases as boiler size increases.

     Requiring excess emission reporting rather than continuous compliance
results in lower cost effectiveness values.   The average cost effectiveness
under excess emission reporting ranges from $225,000/Mg ($205,000/ton) at
the 2.9 MW (10 million Btu/hour) boiler size and 0.26 capacity factor to
$l,040/Mg ($940/ton) at 29 MW (100 million Btu/hour) and 0.55 capacity
factor.

4.2  NATURAL GAS, COMMERCIAL FUEL PRICE

     Tables 6 and 7 present the costs for baseline and LEA control on small
boilers firing natural gas priced for the commercial market sector.  Tables
8 and 9 present  the corresponding cost effectiveness results.  Although
annualized costs for baseline and LEA control are higher with the commercial
gas price than with the industrial natural gas price, the differences in
costs between these two alternatives, as well as the cost effectiveness

-------
values, are smaller.  This is because the commercial gas price is higher
than the industrial price, thus increasing fuel savings and decreasing the
cost difference between baseline and LEA-controlled boilers.
     The cost effectiveness of LEA control with continuous compliance ranges
from $314,000/Mg ($285,000/ton) at the 2.9 MW (10 million Btu/hour) size and
0.26 capacity factor to $2,040/Mg ($l,850/ton) at the 29 MW (100 million
Btu/hour size and 0.55 capacity factor.  When excess emission reporting is
required, cost effectiveness ranges from $225,000/Mg (205,000/ton) for the
2.9 MW (10 million Btu/hour) boiler at a capacity factor of 0.26 to SO/Mg
($0/ton) at the 29 M (100 million Btu/hour) size and 0.55 capacity factor.
There is no net cost increase at this size and capacity factor because fuel
savings are equal to the total nonfuel costs of LEA application.

4.3  DISTILLATE OIL

     Tables 10 and 11 show costs for baseline and LEA-controlled small
boilers firing distillate oil and operating at capacity factors of 0.26 and
0.55, respectively.  Tables 12 and 13 list the corresponding cost-
effectiveness results.
     The distillate oil-fired model boilers exhibit cost and cost-
effectiveness trends similar to those observed for natural gas-fired
boilers.  With continuous compliance, the cost effectiveness of applying LEA
to uncontrolled distillate oil-fired boilers ranges from $156,000/Mg
($141,000/ton) at the 2.9 MW (10 million Btu/hour) boiler size and 0.26
capacity factor to $2,440/Mg ($2,220/ton) at the 29 MW (100 million
Btu/hour) boiler size and 0.55 capacity factor.  For the same range in size
and capacity factor, the cost effectiveness for excess emission reporting
ranges from $112,000/Mg ($102,000/ton) to (-$305/Mg) [-$277/ton].  The
negative cost effectiveness for the latter case results because fuel savings
are greater than the nonfuel LEA costs.
                                      8

-------
 4.4   RESIDUAL OIL

      Costs  for  uncontrolled  and LEA-controlled model boilers  firing residual
 oil  are  presented  in  Tables  14 and  15.  Cost effectiveness  results for the
 residual  oil-fired boilers are given  in Tables 16 and  17.
      Trends in  cost and  cost effectiveness  for firing  residual  oil parallel
 those for firing natural gas and distillate oil.  Fuel  savings  for residual
 oil  due  to  LEA  application are smaller, however, because  of the lower fuel
 price for residual oil compared to  natural  gas.  Also,  there is no change in
 estimated NO emission reductions as  a function of  boiler size.
             A
      Under continuous compliance, the cost  effectiveness  of applying LEA
 to uncontrolled residual oil-fired  boilers  ranges from $104,000/Mg
 ($94,000/ton) at the  2.9 MW  (10 million Btu/hour) boiler  size and 0.26
'capacity factor to $l,610/Mg ($l,460/ton) at the 29 MW (100 million
 Btu/hour) boiler size and  0.55 capacity factor.  For the  same range in size
 and capacity factor,  cost  effectiveness for excess  emission reporting ranges
 from $75,000/Mg ($68,000/ton) to  $576/Mg  ($522/ton).

 4.5  COAL

      Tables 18  and 19 present baseline  and  LEA control costs for coal-fired
 model boilers operating  at capacity factors of 0.26 and 0.55, respectively.
 The corresponding  cost  effectiveness results  are presented in Tables 20 and
 21.  The cost and  cost  effectiveness trends observed for firing coal are
 similar to those exhibited by the other fuel  types.
      Under continuous compliance,  the cost  effectiveness of applying LEA  to
 uncontrolled coal-fired boilers  ranges  from $107,000/Mg ($97,000/ton) at  the
 2.9 MW (10 million Btu/hour) boiler size  and  0.26  capacity factor  to
 $2,350/Mg  ($2,130/ton)  at the 29 MW (100  million  Btu/hour) boiler  size and
 0.55 capacity factor.  For the  same range in  size  and  capacity factor, cost
 effectiveness for excess emission reporting ranges from $78,000/Mg
 ($70,900/ton) to $l,520/Mg ($l,380/ton).
