COAL EXTRACTION AND PROCESSING - WordPress.com
the process of subsurface coal extraction and thermal coal processing. Purpose Coal is used for its potential heat energy when burned and since the 1880s has been widely used to generate electricity in power plants. To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water.

Coal - Wikipedia
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

How a Coal Plant Works - TVA.com
How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
