  • What is coal?

    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. In 2019, about 23 percent of

  • Thermal Power Generation Plant or Thermal Power Station

    May 24, 2014The theory of thermal power stations or the working of the thermal power stations is very simple. A power generation plant mainly consists of alternator runs with help of a steam turbine. The steam is obtained from high-pressure boilers. Generally in India, bituminous coal, brown coal, and peat are used as fuel for the boiler.The bituminous coal is used as boiler fuel has volatile matter from
