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. All condensable PM is assumed to be less than 1.0 ^m in diameter.

^No data are available for cyclone boilers or for atmospheric fluidized-bed combustion (AFBC) boilers. For cyclone boilers, use the factors provided for pulverized coal-fired boilers and applicable control devices. For AFBC boilers, use the factors provided for pulverized coal-fired boilers with PM and FGD controls.

c PM, particulate matter; FGD, flue gas desulfurization.

d CPM-TOT, total condensable particulate matter; CPM-IOR, inorganic condensable particulate matter; CPM-ORG, organic condensable particulate matter; ND, no data.

eFactors should be multiplied by fuel rate on a heat input basis (MM Btu), as fired. To convert to lb/ton of bituminous coal, multiply by 26 MM Btu/ton. To convert to lb/ton of subbituminous coal, multiply by 20 MM Btu/ton.

f S = coal sulfur percent by weight, as fired. For example, if the sulfur percent is 1.04, then S = 1.04. If the coal sulfur percent is 0.4 or less, use a default emission factor of 0.01 lb/MM Btu rather than the emission equation.
