  • Steam consumption for 1 MW of electricity, how much steam

    When we comes to the term of the amount of steam required to produce 1 MW of electricity, it needs to consider so many factors, the most important being, the steam temperature and pressure at the exit of boiler, the isentropic efficiency of turbine, the availability of reheat, the condenser pressure and whether or not any feed water heaters are employed.Learn More

  • 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 Learn More
