SRI/USEPA-GHG-VR-27 September 2003 The ION power meter also continuously measured average power factor across each generator phase. The DAS recorded one-minute averages for each phase during all test periods. The GHG Center reported maximum, minimum, mean, and standard deviation power factors averaged over all three phases. 1.4.4. Emissions Performance Pollutant concentration and emission rate measurements for NOX, CO, THCs, CH4, and CO2 were conducted on the turbine exhaust stack during all of the controlled test periods. Emissions testing coincided with the efficiency determinations described earlier. All of the test procedures used are U.S. EPA reference methods, which are well documented in the Code of Federal Regulations (CFR). The reference methods include procedures for selecting measurement system performance specifications and test procedures, quality control procedures, and emission calculations (40CFR60, Appendix A) [12]. Table 1-4 summarizes the standard test methods that were followed. A complete discussion of the data quality requirements (for example, NOX analyzer interference test, nitrogen dioxide (NO2) converter efficiency test, sampling system bias and drift tests) is presented in the Test Plan.

Results of the instrumental testing are reported in units of parts per million volume dry (ppmvd) and ppmvd corrected to 15-percent O2. The emissions testing was conducted by ENSR International of East Syracuse, NY, under the on-site supervision of the GHG Center field team leader. A detailed description of the sampling system used for each parameter listed is provided in the Test Plan and is not repeated in this report. EPA Method 19 was followed to convert measured pollutant concentrations into emission rates in units of pounds per hour (lb/hr). The fundamental principle of Method 19 is based upon F-factors. F-factors are the ratio of combustion gas volume to the heat content of the fuel and are calculated as a volume/heat input value, (e.g., standard cubic feet per million Btu). This method specified all calculations required to compute the F-factors and provides guidelines for their use. The published F-factor of 8,710 dry standard cubic feet per million Btu (dscf/106Btu) was used to determine emission rates for each controlled test period. Pollutant concentrations were converted from a ppmvd basis to lb/dscf. The emission rates were then calculated using the measured heat input to the turbine [106Btu/hr based on the higher heating value (HHV) of the gas] and stack gas O2 concentration (dry basis) in terms of lb/hr as follows: 1-14PDF Image | Environmental Technology Verification Report
