    The Types of Coal: Composition, Usage, and Energy Value

     · Coking vs. Steam: Coking coal, also known as metallurgical coal, has low sulfur and phosphorus content and can withstand high heat.Coking coal is fed into ovens and subjected to oxygen-free pyrolysis, a process that heats the coal to approximately 1,100 degrees Celsius, melting it and driving off any volatile compounds and impurities to leave pure carbon.

    What is coal? | World Coal Association

    Under conditions favourable to coal formation, the decaying process is interrupted, preventing the release of the stored solar energy. The energy is locked into the coal. Coal formation began during the Carboniferous Period - known as the first coal age - which spanned 360 million to 290 million years ago.

    Health effects of coal - SourceWatch

    Coal Mining. Health effects from coal mining include: the release of methane (CH 4), a potent greenhouse gas estimated to account for 18% of the overall global warming effect triggered by human activities (CO 2 is estimated to contribute 50%).; the release of carbon monoxide (CO) from explosives, which pollutes the air and poses a health risk for mine workers.

    TVA - 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.

    How is coal formed? - Kentucky Coal Education

    In the process of transformation (coalification), peat is altered to lignite, lignite is altered to sub-bituminous, sub-bituminous coal is altered to bituminous coal, and bituminous coal is altered to anthracite. Lignite - is the lowest rank of coal - which means that it has the lowest heating value and lowest carbon content. Although lignite ...
