Coal Drying Improves Performance and Reduces Emissions

Lignite and subbituminous coals from the western U.S. are attractive fuels for power plants, due their low cost and emissions. However, lignite and PRB coals typically contain high amounts of moisture and/or ash. When high moisture coals are burned in utility boilers, about 7 percent of the fuel heat input is used to evaporate fuel moisture.
