Estimating Sulfuric Acid Aerosol Emissions from Coal-Fired

This paper presents a proposed method for estimating the release of H 2SO 4 aerosols from coal-fired utility boilers (item 1 above). In coal-fired plants, H 2SO 4 vapor forms in the ductwork downstream of the boiler by the combination of water vapor and sulfur trioxide (SO 3), both of which are produced during the coal combustion process.

Estimates of Emissions from Coal Fired Thermal …

Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash). The distribution of ash between the bottom ash and fly ash fractions directly affects the PM emission rate and depends on the boiler firing method and furnace type (wet or dry bottom). Boiler load also affects the PM emissions as decreasing load
