Thermalbased power plants can produce electricity from coal or other fuel sources. The coalfired 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. Learn how the process works as well as interesting ...

The coal at this stage is finely ground and very dry, both of these characteristics aid combustion. Combustion occurs and heat is generated (this plant is a 'thermal power plant'). The heat generated by the water tube boiler is used to change the state of water to steam. The steam is then discharged to a condenser steam turbine.

The superheater's temperature is the highest among all components of the thermal power plant. In the thermal power plant; there are three types of superheaters used; convection, radiant, and separately fired. The superheater is used to increase the temperature of the steam generated from the boiler.

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 ...

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 ...

The overall coal plant efficiency ranges from 32 % to 42 %. This is mainly dictated by the Superheat and Reheat steam temperatures and Superheat pressures. Most of the large power plants operate at steam pressures of 170 bar and 570 °C Superheat, and 570 ° C reheat temperatures. The efficiencies of these plants range from 35 % to 38 %.
