The operation of a coal power plant is on the basis of the Rankine cycle. For power to be generated, there are three principle inputs which are very essential. These include coal, air and water. Coal is used as the fuel and is combusted to generate the required heat energy in the furnace. To accelerate the rate of combustion in the furnace and also to enhance the flow of flue gases within the ...
2. Process description of a coal-fired power plant A coal-fired power plant burns coal to produce electricity. In a typical coal-fired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.
Jun 16, 2014 A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. Rankine cycle Coal is used as a fuel to heat water in a coal based thermal power plant.
- For the combustion process in a coal-fired power plant, the opacity of the flue gas exhaust emissions is one of the performance measures, which has to comply with the mandatory standards for environmental protection. This power station produces the electrical power by using the good quality
