Coal drying. Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coalor gasfired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...
