· After switching from regular coal to refined coal in November 2016, this plant showed no obvious reductions in emissions rates for NO (top right), SO₂ (bottom left), or mercury (Hg, bottom right). The plant did not install or dismantle pollution control equipment or change coal suppliers during this period, so we should be able to observe the emissions impacts—if any—of refined (versus ...
READ MORE· Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.

READ MOREWhat is coal used for? Coal is primarily used as fuel to generate electric power in the United States. In coal-fired 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 high-pressure steam, which drives a turbine, which produces electricity.
