    What is a coal fired power plant? | AnswersDrive

    Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to …

    • how to calculate the coal quantity used in a power plant

      How to Calculate the Coal Quantity Used in a Power Plant

      After considering the conversion efficiency in a power plant we require an heat input of (3600 / 33.44% ) 10765 kJ/ kw hr. Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1,000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW.

      How Coal Works | Union of Concerned Scientists

      Because coal is only mined in a few regions of the country, it typically needs to be transported before being burned in a power plant. Wyoming’s Powder River Basin coal, for example, is shipped by rail to power plants as far away as Georgia. Trains move roughly 70 percent of the coal that’s transported in the United States every year
