Introduction. Coal is the dominating fuel source used in thermal power plants for generation of electricity. At the coalfired thermal power plants, the raw coal is first pulverized to the shape of flour before it is forcefed to the furnace. During the pulverization process, the clay particles entrapped in the cracks of coal get separated ...

Thermal power plant development started in 1866 when Werner von Siemens built the first dynamo for power generation. Years later in 1882, Thomas Edison developed the first central power station in New York [37]. In the first steam generators, the generated steam to drive the DC dynamos is either lowpressure saturated or slightly superheated.

Coal fired power plants follow the Rankine cycle in order to complete this process. Since they require plenty of water to be circulated in this cycle, coal power plants need to be located near a body of water. The process of coal fired plants can be seen below in Figure 3. Figure 3. The process of a coal fired power plant to convert coal into ...

Thermal Power Plant Working Principle. In Thermal Power plants, the heat of combustion of fossil fuel (Coal, oil, or gas) is utilized by the boiler to turn water into steam with high pressure and temperature. The coal is broken into pieces for easy combustion to heat the water in the boiler. From the boiler, the steam is passed through the ...

7. Steam (Thermal) Power Plant circuits. Coal and Ash circuit Pulverised coal from the storage area (called stack) is taken to the boiler by means of coal handling equipment such as belt conveyors, bucket elevators etc. Note : A thermal power plant of 400 MW capacity requires 5000 to 6000 tonnes of coal per day. After the pulverised coal is burnt at 15000C to 20000C by combustion it gets ...

2. Process description of a coalfired power plant. A coalfired power plant burns coal to produce electricity. In a typical coalfired 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.
