Coal-fired power station - Wikipedia

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

How much coal is required to generate 1 MWH of …

9/3/2017 · One KW is 3600 kj per hour. Therefore, at 21% efficiency, we need a heat input of about 7,560 kj/hr (3600/21%) - therefore for producing 1 kw/hr electriccity, we need 7,560/20,000 or 0.378 kg of coal. For a megawatt/hr we would need 0.378 x 1000 = 378 kg of coal - we can round it off to 400 kg. Keyword: Industry steam boiler, boiler generate 1
