Coalfired power station Wikipedia
A coalfired power station is a type of fossil fuel power stationThe coal is usually pulverized and then burned in a pulverized coalfired boilerThe furnace heat converts boiler water to steam, which is then used to spin turbines that turn generatorsThus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy
