Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

Mar 18, 2017· Thermal power plant uses steam energy for the generation of the electricity. Fossil fuels like coal, oil, natural gases are burnt in the boiler, a hot flue gases thus generated are used to heat the feed water. A superheated steam is generated. This steam under high pressure then expanded in stem turbine to rotate the … Continue reading Construction and working of thermal power plant
