How much coal is required to generate 1 MWH of electricity?
Mar 09, 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

After the steam engine was invented, James Watt, an inventor and engineer, worked on improving it and on making it more efficient. Power is one indicator of efficiency — if a given engine is modified and its power output increases, so does its efficiency. To show the efficiency of the improved engine Watt suggested horsepower as a unit of power.
