Analy- ses of the samples were performed at the YRC laboratory in Stamford, Connecticut under the direction of Mr. Robert Q. Bradley. Mr. Robert Phillips of Radian Corporation was responsible for monitoring the process operations during the testing program. Personnel from Radian Corporation will provide the Process Description and Operations section which will be filed separately from this report (refer to Section 3.1). Personnel from the Sorg Paper Company in Middletown, Ohio, whose assistance and guidance contributed greatly to success of the test program, included Mr. Jeff Downs, Power House Super- visor. Mr. Dennis Holzschuh of the Office of Air Quality Planning and Standards, Emission Measurement Branch, USEPA, served as Tech- nical Manager and was responsible for coordinating the emission test program. 111 ------- 1.0 INTRODUCTION Section 111 of the Clean Air Act of 1970 charges the Adminis- trator of the United States Environmental Protection Agency (USEPA) with the responsibility of establishing federal stan- dards of performance for new stationary sources which may sig- nificantly contribute to air pollution. When promulgated, these standards of performance for new stationary sources (NSPS) will reflect the degree of emission limitation achiev- able through application of the best demonstrated emission con- trol technology. To assemble this background information, the USEPA utilizes emission data obtained from controlled sources involved in the particular industry under consideration. Based on the above criteria, the USEPA1s Office of Air Quality Planning and Standards (OAQPS) selected the Sorg Paper Company in Middletown, Ohio as a site to conduct -an emission test pro- gram. York Research Corporation (YRC), under EPA Contract: Number 68-02-2819, Work Assignment Number 24, was requested by the USEPA to conduct the emission test program at Sorg Paper. This request was based on a pre-survey conducted at the plant on March 19, 1980. The test program was designed to provide a portion of the emission data base required for establishing the SPNSS for industrial boilers. This plant is considered to employ process and emission control technology representative of industrial boiler facilities. There is one industrial boiler that produces process steam for the operations at the Sorg Paper plant. Emissions from the boiler are controlled by a multiclone followed by a venturi scrubber. Emission sampling was conducted during the week of April 21, 1980 at the following test locations: ------- Inlet to Multiclone Scrubber Outlet Concurrent tests performed at the inlet and outlet locations provided data on velocity, moisture, ga's composition and parti- culate emission rates. A total of four tests were conducted during the test program, three while the boiler was operating normally, and one during a typical soot blow cycle. Samples were collected and analyzed in accordance with the prescribed EPA methods. One coal sample was taken during each test run. Visible emissions observations were conducted on the scrubber outlet stack to obtain average percent opacity measurements. Four particle size distribution tests were performed at the inlet location. The following sections of this report include: Summary and Discussion of Test Results Process Description and Operation Location of Sampling Points Sampling and Analytical Procedures ------- 2.0 SUMMARY AND DISCUSSION OF TEST RESULTS 2.1 Introduction The results of the emission test program conducted at: the Sorg Paper Company in Middletown, Ohio during the week of April 21, 1980 ,are presented throughout this section. Samples were collected concurrently at the multiclone in- let and the scrubber outlet. Preliminary pitot traverses and moisture measurements were conducted at each location, and the parameters necessary to maintain proper isokinetic sampling were determined based on these preliminary tests. All samples were sealed in clean containers and transported to the YRC laboratory in Stamford, Connecticut for analyses. Problems encountered in the sampling pro- gram and deviations from normal sampling procedures are discussed in Section 5.0, "Sampling and Analytical Pro- cedures". 2.2 Particulate Results The results of the particulate emission tests conducted at the two locations are summarized in Tables 2-1 through 2-8 (refer to Appendix 6.3 for field data sheets). A compari- son of the data from-the inlet and outlet locations, as well as the removal efficiency of the multiclone and scrubber, are presented in Tables 2-5 and 2-6. The col- lection efficiency calculations are based on particulate concentration. The average removal efficiency for the four tests was 98.47%. 2.3 Gas Compositon Results The results of the gas composition analyses are shown in Table 2-7. Orsat analyses were performed on the flue ------- gases at each sampling location. The field data sheets for these analyses appear in Appendix 6.3. 2.4 Visible Emissions Observation Results Visible emissions observations were conducted on the scrubber outlet stack simultaneously with the particulate emission tests. Summaries of these observations appear in Table 2-10. The locations from which these observations were made are presented in Figure 4-5. The average opacity observed during the test program did not exceed three percent. The field data sheets for these observa- tions may be found in Appendix 6.3. 2.5 Fuel Samples Results Samples of the coal used in the boiler were obtained by a member of the YRC test team during each of the four par- ticulate tests. The results of the analyses appear in Table 2-8. 2.6 Particle Size Distribution Results The results of the particle size distribution tests con- ducted at the inlet location are summarized in Table 2-10 and illustrated in Figures 2-1 and 2-2. (Refer to Appendix 6.3 for field data sheets). Three tests were conducted under normal conditions and one test was run during the soot blow cycle. It was not possible to perform particle size distribution tests at the outlet location due to the size of the ports. It was necessary to use a heating collar on the Andersen sampler because of the moisture content in the stack gas at this location. The heating collar adds ------- approximately one half inch to the diameter of the sampler which made it impossible to fit it through the port opening. ------- TABLE 2-1 SUMMARY OF EMISSION TEST RESULTS MULTICLONE INLET SORG PAPER COMPANY .MIDDLETOWN, OHIO (English Units) Date Time Volume Of Dry Gas Sampled (DSCF)b Percent Moisture By Volume Average Stack Temperature, °F Stack Volumetric Flow Rate (DSCFM)C Percent Isokinetic Total Particulate - Filter Catch and Front Half Acetone mg gr/DSCF Ib/hr Test 1 4/23/80 0911-1140 80.90 3.3 340 24241 99.6 14259.63 2.71460 564.05 Test 2 4/23/80 1340-1519 57.24 5.8 280 25465 100.6 9010.95 2.42429 529.15 Test 3a 4/23/80 1615-1754 57.83 4.4 285 25340 102.2 10332.98 2.75163 597.65 Test 4 4/24/80 0914-1053 59.52 6.0 280 25295 105.3 7828.86 2.02562 439.18 Average 63.97 4.9 296 25085 101.9 10358.10 2.47904 532.51 aSoot blow conducted during this test for 7 minutes (1628-1635). bDry Standard Cubic Feet at 68°F, 29.92 inches Hg.

For this reason the Process Description will be filed separately from the report. 18 ------- 4.0 TESTING LOCATIONS 4.1 Sampling Locations Particulate sampling was conducted simultaneously at the inlet and outlet locations. The locations of the test ports and sampling points were determined in accordance with EPA Method 1 (Sample and Velocity Traverses for Stationary Sources)^-. Multiclone Inlet The four test ports for the multiclone inlet are located in the rectangular duct which vents the exhaust gas from the boiler to the multiclone. The duct dimensions are 60 inches by 36 inches (45 inch equivalent diameter). The ports are located 1.7 diameters from an upstream bencl in the duct and 1.8 diameters from a downstream bend (Figure 4-1). Twelve points per port were required for sampling. During test 1, each point was sampled for 3 minutes, re- sulting in a total test time of 144 minutes. The sampling time was reduced to 2 minutes per point for the subsequent tests 2-4 (refer to Section 5.4, pg. 29). Particle size distribution samples were obtained at point A- 2. Scrubber Outlet The scrubber outlet stack is 54 inches (inner diameter) at the sampling location. Two perpendicular test ports are test methods cited in this report are contained in 40 CFR 60, August 18, 1977. 19 ------- 36 Al »B1 . Cl .D * 9 * O o e . 0 < o v o «A12 B12.

The button-hook nozzle was made of 316 stainless steel. Probe The liner for the sample probe was made of 316 stainless steel. A heating system, capable of maintaining a gas temperature of 248 + 25°F at the exit end, was built into the probe. A thermocouple, used to monitor gas tempera- tures, was attached to the probe. A precalibrated Type S pitot tube was attached to the probe to allow constant monitoring of the stack gas velocity. The pitot tube was constructed in accordance with EPA Method 2. Filter Holder A tared fiberglass filter was encased in a borosilicate glass filter holder. A glass frit supported the filter. A silicone rubber gasket was used to provide a positive seal against leakage from around the filter. -The filter holder was contained in a heated box capable of maintain- ing a temperature of 248 _+ 25°F. A thermocouple attached to a pyrometer was used to monitor the temperature inside the sample box. 24 ------- Impinger Train The train consisted of a series of four impingers con- nected with leak-free ground glass fittings. The first, third and fourth impingers were of the Greenburg-Smith design, modified by replacing the tip with 1.3 cm ID glass tube. The tube extends to approximately 1.3 cm from the bottom of the flask. The second impinger was of the Greenburg-Smith design with the standard tip. The im- pinger train was contained in an ice bath to cool the sample gas stream. A dial type thermometer, capable of measuring temperatures to within 2°F was placed at the outlet of the fourth impinger for monitoring purposes. Metering System A R.A.C. Train Stack Sampler^ was used for the metering system. The system consists of the following: Calibrated orifice Vertical, inclined, dual manometer Dry gas meter (capable of measuring volume within 2 percent) Vacuum gauge Leak-free pump Thermometers (capable of measuring temperatures within 5.4°F) Electrical controls for sampling The orifice and dry gas meter were calibrated in accord- ance with APTD-05762. 1Research Appliance Company, Gibsonia, PA.

No. APTD-0576, Office of Air Programs, EPA, Research Triangle Park, NC 1972. 25 ------- 5.3 Preliminary Measurements Gas Velocity and Temperature Gas velocity and temperature were measured at each sam- pling location in accordance with guidelines outlined in EPA Method 2 (Determination of Stack Gas Velocity and Volumetric Flow Rate). The velocity pressure was measured on an inclined, dual manometer and the temperature was measured on a pyro- meter. Measurements were recorded at each traverse point. Moisture Determination The moisture content of the stack gas at each test loca- tion was determined in accordance with guidelines outlined in EPA Method 4 (Determination of Moisture Content in Stack Gases). A sample of the stack gas was extracted at one traverse point for twenty minutes at each test location. The dry gas meter readings, orifice pressure differential (in. H20) and meter temperatures were recorded every five minutes. The calculations for moisture content can be found in the Appendix. 5.4 Particulate The particulate emissions from the boiler were determined in accordance with guidelines outlined in EPA Method 5 (Determination of Particulate Emissions from 'Stationary Sources). 26 ------- Sampling The sampling train at each test location consisted of the nozzle, probe, filter holder, impinger train and metering system. The sampling apparatus was set up as shown in Figure 5-1. All connections were leak-free. The nozzle size was determined using data obtained from the preliminary measurements. The first and second impingers were each initially filled with 100 ml of distilled water. The third impinger was left empty. The fourth impinger was filled with 300 g of pre-weighed indicating type silica gel. During each test, the following data were recorded at each traverse point: Point designation Clock time (24-hour clock) Dry gas meter reading (Vm, Velocity pressure (aps, in Desired pressure drop across orifice (AH, in. H20) Actual pressure drop across orifice (AH , in. H20) Stack temperature (Ts, °F) Dry gas meter temperature at inlet and outlet (Tm, °F) Vacuum gauge reading (in.

Initial and final leak checks were performed on each sampling train prior to and upon completion of each test to confirm the presence of a leak-free system. Leakage rates did not exceed 0.02 cfm per EPA standards. All measurements were recorded on the data sheets. Upon completion of the first test, the sampling procedure was modified. The volume of dry gas sampled at each loca- tion was higher than required by EPA Method 5. To compen- sate for .this, the total sampling time was reduced from 144 minutes to 96 minutes per test at the inlet location,, and from 140 minutes to 100 minutes at the outlet location for the remainder of the sampling program. The plant was operating the boiler at 52,000 Ibs./hr. throughout the test program. During the fourth test, a typical soot blow cycle was conducted for 7 minutes. Sample Recovery Upon completion of each test, the sampling trains were dis- assembled to permit sample recovery. The samples were re- covered in the following manner: 29 ------- Container #1 - The filter was removed from the filter holder and placed in its original container which was sealed with adhesive tape. Container #2 - The nozzle, probe and front half of the filter holder were rinsed with acetone three times. The wash was stored in a . . glass sample jar with a teflon-lined lid. The jar was sealed with adhesive tape and the liquid level was marked. Container #3 - The silica gel was returned to its original container. Container #4 - A sample of the acetone reagent was placed . in a glass sample jar with a teflon-lined lid which was sealed1with adhesive tape. Each sample container was labeled with the date, test location, test number and contents. The volume of water in the first three impingers was measured and recorded on the data sheets and the water was discarded. Sample Analysis Each sample was analyzed in the following manner: Container #1 - The filter was removed from its sealed con- tainer and placed on a tared watch glass. The filter and watch glass were dessicated over anhydrous CaSO^ for 24 hours and weighed to a constant weight. The weight was recorded to the nearest 0.01 mg. Container #2 - The acetone washings were transferred to a tared beaker. The acetone was evaporated 30 ------- at ambient temperature and pressure. The beaker was dessicated for 24 hours and weighed to a constant weight. The weight was recorded to the, nearest 0.01 mg. Container #3 - The silica gel was weighed on a beam balance and the weight was recorded to the nearest 0.1 gram. Container #4 - The acetone blank was transferred to a. tared beaker. The acetone was evaporated at ambient temperature and pressure. The beaker was dessicated for 24 hours and weighed to a constant weight. The weight was recorded to the nearest 0.01 mg. This weight was subtracted from the final weight of the contents of container #2 to obtain the net weight of particulate in the front half wash. 5.5 Gas Composition The gas composition was determined in accordance with EPA Method 3 (Gas Analysis for Carbon Dioxide, Oxygen, Excess Air and Dry Molecular Weight). Multi-point integrated gas samples were collected in an evacuated Tedlar bag with a stainless steel sample line and vacuum pump. The gas was analyzed for CC>2/ 02 and CO immediately after collection. 5.6 Fuel Samples (Coal) Sampling Individual coal samples were collected by a member of the YRC test team during each of the four particulate test 31 ------- runs. The samples were placed in glass sample jars with teflon-lined caps. Each jar was labeled with the date, test location, test number, contents and sample number. Analysis Representative samples of the coal obtained during each test run were analyzed at YRC laboratory in Stamford, Connecticut in accordance with guidelines outlined in the following ASTM established procedures.2 Proximate Analysis of Coal A proximate analysis of coal is defined by ASTM as an "assay of the moisture, ash, volatile matter and fixed carbon".3 The standard test methods for these analyses are designated by ASTM as: Moisture; Method D3173 Ash; Method D3174 Volatile Matter; Method D3175 Fixed Carbon; There is no direct ASTM method of determining fixed carbon. It can be calculated according to the equation; % Fixed Carbon = 100 - (% Moisture + % Ash + % Volatile Matter) ^1978 Annual Book of ASTM Standards, Part 26, American Society of Testing and Materials, Philadelphia, Pennsyl- vania, 1978, pp. 380-427. 3Ibid, p. 380 32 ------- Ultimate Analysis of Coal An ultimate analysis of coal is "the determination of carbon and hydrogen in the material, as found in the gaseous products of its complete combustion,, the deter- mination of sulfur, nitrogen and ash in the material as a whole, and the calculation of oxygen by difference."'* The standard test methods for these analyses are desig- nated by ASTM as: Carbon and Hydrogen; Method D3178 Sulfur; Method D3177 Nitrogen; Method D3179 Ash; Method D3174 Oxygen; There is no direct ASTM method of determining oxygen. It can be calculated according to the equation: % Oxygen = 100 - (% Carbon + % Hydrogen + % Sulfur + % Nitrogen + % Ash) Moisture; Method D3173 Gross Calorific Value; Method D2015-17 5.7 Particle Size Distribution The particle size distribution samples were collected using an Andersen Cascade Impactor. The impactor aero- dynamically classifies particles into multiple size ranges. It consists of eight stages and a back-up filter 4Ibid, p. 390 33 ------- (Figure 5-2). Each stage consists of a configuration of orifices of specific diameters above a collection plate. Tared glass fiber substrates were used on each stage as collection media. Different sized particles are impacted on each stage cor- responding to the size of the orifices on the plate above the collection substrates. The range of particle sizes retained on each substrate varies according to the velo- city of the gas (as determined by the sample rate), the gas viscosity and the particle density. Since the ori- fices are arranged in descending diameters/ the gas velo- city increases and the particle size collected on each stage decreases. Sampling The sampling apparatus consisted of an Andersen impactor, eight pre-tared substrates and a pre-tared backup filter, nozzle, drying tube, vacuum pump, dry gas meter, cali- brated orifice and manometer. During the soot blow cycle a preseparator was used to pre-cut particles above 1C) microns and avoid overloading the collection substrates. (See Figure 5-3 for sampling train diagram). The sample train was checked for leaks at the completion of each sample run. Any leak rate above 0.02 cfm was con- sidered unacceptable. Using data obtained from the velocity traverse, a sampling rate (AH) was calculated. (Refer to Appendix 6.2 for calculations). During each test the following data were recorded: 34 ------- Point designation Clock time (24-hour clock) Dry gas meter readings (Vm, Actual pressure drop across orifice ( H, in H20) Dry gas meter temperatures (Tm, °F) Pressure drop, in stack (in. Hg) Vacuum (in. Hg) Sample Recovery The Andersen impactor was disconnected from the probe and brought to the clean-up area. The samples were recovered in the following manner: The nozzle and the front half of the impactor were rinsed with acetone. The rinse was stored in a clean glass sample ja-r with a teflon-lined lid. The jar was sealed with adhesive tape and the liquid level was marked. Starting with stage I, the fiberglass substrates were removed from the impactor and returned to their original containers. There were a total of 8 substrates and one backup filter for each sample. When a preseparator was used, it was rinsed with acetone and the contents were stored in a sepa- rate glass sample jar with a teflon lid. The jar was sealed with adhesive tape and the liquid level was marked. Sample Analysis The samples were analyzed in the following manner: 35 ------- The fiberglass substrates and the backup filters were dessicated and weighed to a constant weight. The net weight gain was recorded to the nearest 0.01 mg. The acetone rinse was transferred to a tared beaker. The beaker was heated to a temperature well below the boiling point until the acetone was evaporated. The beaker was then dessicated and weighed to a constant weight. The net weight gain was recorded to the nearest 0.01 mg. 36 ------- ANDERSEN STACK SAMPLER JET STAGE (9 TOTAU NOZZLE BACKUP FILTER GLASS FIBER COLLECTION SUBSTRATE CYCLONE PRESEPARATOR INLST CORE ATE HOLDER I I FIGURE 5-2 ------- ANDERSEN SAMPLING TRAIN ANDERSEN SAMPLER OAS METER ORIFICE MANOMETER ES-094 FIGURE 6-3 38 ------- YRC PROJECT NO. 01-9517-24 Prepared by: Laurie Behr Project Scientist Emissions Measurement Dept, Reviewed by: Roger£ A.
