Description:
In general, the total hydrocarbon (THC) analyzers performed well. The only problems occurred when the flame failed to reignite after an automatic backpurge cycle (nine times), and on one occasion when a sample line plugged. Average THC concentration, normalized to 7% O2, was 108 parts per million by volume (ppmv) for Site THC-1, and 8 ppmv for Site THC-2. Although CO and O2 analyzers worked well in the beginning of the study, there were serious problems with the sample conditioning system originally assembled for these two analyzers. Successful operation was achieved after the sample conditioning system was redesigned. Correlation of THC and CO data showed a positive but not close correlation. Correlation of THC concentrations with breaching temperature was not possible.An evaluation of using the data collected to improve furnace operations permitted normalized THC concentrations of less than 30 ppmv to be achieved for periods of up to five hours. Several one-hour tests of an afterburner gave similar results at afterburner temperatures as low as about 1,080 degrees F.
