Coal-fired power station - Wikipedia
OverviewOperationCoal power generationCarbon dioxide emissionsPollutionTransport and delivery of coalEfficiencyEconomicsAs a type of thermal power station, a coal-fired power station converts chemical energy stored in coal successively into thermal energy, mechanical energy and, finally, electrical energy. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The heat from the burning pulverised coal converts boiler water to steam, which is then used to spin turbines that turn generators. Compared to a thermal power station burning other fuel types, coal specific fuel processing and ash disposal is required. Wikipedia & 183; CC-BY-SA 许可下的文字
