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 ...
Coal Gasification Option An alternative option generating significant interest in India is the use of a coal gasification plant in combination with a Direct Reduction plant.

Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.
EAFs do not use coal directly as a raw material, but often rely on coalfired electric power. In addition, up to about 150 kg of coal (or coke) per tonne of steel is used for carburizing as well as for producing gases needed to create a foam which protects the electrodes.
