I. INTRODUCTION

On 15 Nov 89, source emission testing for particulates, carbon monoxide(CO), total hydrocarbons (HC), sulfur dioxide (SO2), and nitrogen oxides (NOx)was conducted on the Gas Turbine Engine Test Facility, Bldg 340, by personnelfrom the Air Quality Function of the AF Occupational and Environmental HealthLaboratory Environmental Quality Division (AFOEHL/EQ). This survey wasrequested by SA-ALC/EM to determine emission data on various gas turbineengines. The emission data will be used to initiate a permit application fora new Gas Turbine Engine Test Facility. Personnel involved with on-sitetesting are listed in Appendix A.

II. DISCUSSION

A. Background

SA-ALC/EM requested emission data on various gas turbine engines.This information is required to initiate a permit application for a new GasTurbine Engine Test Facility. No emission data could be located for two ofthe engines. SA-ALC/EM then requested source emission testing at the existingfacility to determine emission data for these gas turbine engines.

B. Site Description

The Gas Turbine Engine Test Facility, Bldg 340, is a one storybuilding located on Kelly AFB. The building is divided into several testcells (Fig 1). Cells 8 and 15A were selected for emission testing. Theexhaust stacks for cells 8 and 15A are shown in Figures 2 and 3,respectively. Cell 8 was used to test gas turbine engine GTCP 85-180. Cell15A was used to test jet fuel starter F-15 JFS.

C. Sampling Methods and Procedures

Federal Regulations require that stack emission testing be conductedin accordance with Appendix A and B to Title 40, Code of Federal Regulations,Part 60 (40 CFR 60). Determination of gas turbine engines emissions is to bedone in accordance with Title 40, Code of Federal Regulations, Part 87.Therefore, sample train preparation, sampling and recovery, calculations andquality assurance were done in accordance with the methods and proceduresoutlined in 40 CFR 60 and 87.

Five sampling ports were installed on one side of the rectangularstacks resulting in five traverses of the stack cross-section. The ports onCells 8 and 15A were installed approximately 1 and 1.5 duct diameters upstreamand 2.8 and 4 duct diameters downstream from any flow disturbance,respectively. Based on the inside stack diameter, port location and type ofsample (particulate), 25 traverse points (5 per traverse) were used to collecta representative sample.

Prior to the emission test on each stack, cyclonic flow was determinedby using the Type S pitot tube and measuring the stack gas rotational angle ateach traverse point. Flow conditionq were considered acceptable when thearithmetic mean of the rotational angles was 20 degrees or less. Apreliminary velocity pressure traverse was also accomplished concurrently.

Particulates and sulfur oxides (S02) were collected and analyzed according toEPA method 8. Normally, three minimum one hour runs constitute a test;however, because jet fuel starters, as opposed to aircraft engines, can onlyoperate for abbreviated periods, only one 62.5 minute run constituted a test.

The EPA method 8 sampling train (Figure 4) consisted of a button-hookprobe nozzle, heated inconel probe, heated glass filter, impingers and apumping and metering device. The nozzle was sized prior to each stack test sothat the gas stream could be sampled isokinetically. In other words, thevelocity at the nozzle tip was the same as the stack gas velocity at eachpoint sampled. Flue gas velocity pressure was measured at the nozzle tipusing a Type S pitot tube connected to a 10-inch inclined-vertical manometer.Type K thermocouples were used to measure flue gas and sampling train temper-atures. The stainless steel probe liner was heated to minimize moisturecondensation and the heated filter was used to collect particulates. Theimpinger train consisted of four impingers. The first and third impingerswere standard Greenburg-Smith designs and the second and fourth impingers weremodified Greenburg-Smiths. The first impinger contained an 80% solution ofisopropanol and the second and third impinger each contained a 3% hydrogenperoxide solution. The fourth impinger contained silica gel. This systemcollected the water and SO2 from the gas stream. Moisture was subsequentlydetermined according to EPA method 4. The pumping and metering system wasused to control and monitor the sample gas flow rate.

Hydrocarbons were collected using a sampling train which consisted ofa metal probe, two charcoal tubes connected in series, and a pump. The pumpwas calibrated before and after sampling.

Carbon monoxide (CO) was continuously monitored according to EPAmethod 10 using Neotronics (model C0101) direct reading equipment. However,ascarite and silica gel tubes were not used in the sampling train to removeC02 and water, since C02 and water were considered to be too low inconcentration to be a significant interference in the CO infrared absorptanceband used. Carbon monoxide monitor was calibrated using known concentrationsof CO (0, 24, 55, and 100 parts per million). Calibration was accomplishedaccording to EPA method 10. (Appendix F)

Nitrogen oxides were monitored using an Anarad Continuous EmissionMonitor (CEM) according to EPA method 7E. The CEM consisted of a metal probe,heated umbilical, sample conditioner and NOx analyzer. Nitrogen oxideanalyzer was calibrated using known concentrations of NO (0, 50, 155, 250, and348 parts per million). Calibration was accomplished according to EPA method20. (Appendix F)

Oxygen (02) and carbon dioxide (C02) were collected and analyzedaccording to EPA method 3. The sampling train and ORSAT analyzer are shown inFigures 5 and 6.

EPA methods calculations were made using the Environmental ProtectionAgency publication entitled, "Source Test Calculation and check programs forHewlett-Packard 41 Calculators," (EPA-340/1-85-013) and associated softwareprograms. Equipment calibration data is shown in Appendix F.

III. CONCLUSIONS

Both engines ran very clean; however, it is important to note thattypically particulates and hydrocarbons concentrations are inverselyproportional to the engine thrust or power setting; while nitrogen oxides andcarbon monoxide emissions are proportional to thrust. Therefore, this testdoes not give an accurate indication of the maximum particulate and hydro-carbon emissions. However, maximum hydrocarbon emissions could be estimatedby comparing the data of this report with emissions of other gas turtineengines.

IV. RECOMMENDATIONS

The Kelly AFB Gas Turbine Engine Test Facility, Bldg 340, is meeting TexasAir Control Board standards. No further action is necessary at this time.

The data contained in this report should be used as an estimate ofemissions from the F-15 JFS and GTCP 85-180 and used to initiate a permitapplication for a new Gas Turbine Engine Test Facility.

CALCULATION OF MASS EMISSION RATES

1. Mass emission rates for gas turbine and piston engines were calcu-lated using the formulas specified by EPA.

For gas turbine engines, these formulas are:

(HG)

HC emission rate = M [ (oO) + ]( + ) 10O + (COD) + 10 -

Mco _(CO)FCO emission rate = 1014

(CO)(HG) 1(MC + cMH) r c104 + (CO2) + ---- r-

NONOx emission rate =MNO 2

+ H) L 1 04 + (CO2) +

2. Emission rates for hydrocarbons, carbon monoxide, oxides of nitro-gen, and particulates also are expressed as pounds per 1000 pounds of fuel.These values are obtained by dividing the emission rate, expressed as poundsper hour, by the fuel flow (pounds per hour) and multiplying by 1000.

39

where:

HC emission rate = Pounds per hour of exhaust hydrocarbons emitted inan operational mode

CO emission rate = Pounds per hour of exhaust carbon monoxide emittedin an operational mode

NOx emission rate = Pounds per hour of exhaust oxides of nitrogen emittedin an operational mode

MHC = Molecular weight of methane, MHC = 16.04

MCO = Molecular weight of carbon monoxide

MNO2 = Molecular weight of nitrogen dioxide

MC = Atomic weight of carbon

MH = Atomic weight of hydrogen, MH = 1.008

a = Atomic hydrogen - carbon ratio of fuel(equal to 2 in approximation equations)

(HC) = Concentration of hydrocarbons in the exhaust sample in parts permillion carbon equivalent, i.e., equivalent propane x 3.

(CO) = Concentration of carbon monoxide in the exhaust sample in partsper million by volume.

(CO2) = Concentration of carbon dioxide in the exhaust sample in volumepercent

(NOx) = Concentration of oxides of nitrogen in the exhaust sample in partsper million by volume, NO + NOx.

F = Mass rate of fuel flow in pounds per hour.
