| Abstract |
The paper gives results of a recent series of low-concentration nitrogen oxides (NO-x) emission measurements, made by Midwest Research Institute (MRI) a NO-x control system called Xonon(trademark) Cool Combustion. (NOTE: Some in industry question the capability of certain existing EPA Reference Methods to accurately and precisely make low-concentration emission measurements, noting that the methods were not developed for such low-concentration applications). The Cool Combustion systems produced between 1 and 2 ppmv of NO-x emissions. Because the Cool Combustion system was installed on a gas turbine, EPA Method 20 was followed to measure the NO-x and oxygen (O2) concentrations in the turbine exhaust. The measurement range for the Thermo Environmental Instruments (TEI) Model 42H NO-x analyzer was 0 to 20 ppmv. All Method 20 quality control (QC) procedures were followed strictly. Test program results indicated that low-concentration NO-x emission measurements can be made accurately. The paper details the test program and sampling system used to make the low-concentration NO-x emission measurements. Results of the QC checks and the mean and 95% confidence interval of the mean of 12 test runs are reported. |
