A coal-fired power station is a type of fossil fuel power station.The coal is usually pulverized and then burned in a pulverized coal-fired boiler.The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy.
Coal is primarily used as fuel to generate electric power in the United States. The coal is burned and the heat given off is used to convert water into steam, which drives a turbine. In 2012, about 39 percent of all electricity in the United States was generated by coal-fired power plants, according to the U.S. Energy Information Administration.
Coal plays a vital role in electricity generation worldwide. Coal-fired power plants currently fuel 38% of global electricity and, in some countries, an even higher percentage.
