t e m a Data from EPA, Compilation of Air Pollutant Emission Factors, AP-42, Fifth ed., U.S. Environmental Protection Agency, U.S. Government Printing Office, Washington, D.C., January 1995. Tons are short tons. To convert from lb/ton to kg/Mg, multiply by 0.5. Emission factors are pounds of pollutant per ton of coal combusted, as fired. ESP, electrostatic precipitator. ^Expressed as aerodynamic equivalent diameter.

cA = coal ash weight percent (wt.%) as fired; for example, if coal ash weight is 8.2%, then A = 8.2. dEmission factor rating: C.

eEstimated control efficiency for multiple cyclones is 80%; for scrubber, 94%; for ESP, 99.2%; and for baghouse, 99.8%. f Emission factor rating: E. gEmission factor rating: D.
