Description:
The report describes the second year's activities of a comprehensive EPA-funded study of a commercial fabric filter on a 350-MW low sulfur coal-fired unit at Southwestern Public Service Company's Harrington Station, near Amarillo, Texas. Special tests were performed to characterize gaseous and particulate emissions, to evaluate fabric performance, and to optimize the fabric filter system's performance. Tests will continue. Test results confirmed that the unit can operate in compliance with the existing New Source Performance Standard (NSPS) of 0.1 lb/million Btu. Because NOx concentrations were consistent at all five sampling locations, NOx will be excluded from future testing. Test results from the stack indicated that the unit can meet existing NSPS for SO2; results correlated well with stoichiometric calculations. During other tests: mass emissions of particulate measured at the stack ranged from 0.007 to 0.034 lb/million Btu; average particulate collection efficiency was about 99.3%; the mean particle diameter was 5.4 micrometers at the stack exit; SO2 emissions were within NSPS of 1.2 lb/million Btu; NOx emissions were consistent across the entire baghouse; and SO3 emissions ranged from 0.3 to 3 ppm.
