Coal fired power plant Energy Education

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.

How Fossil Fuels are Used to Generate Electricity

Most traditional power plants make energy by burning fuel to release heat. Thus, they are called thermal (heatbased) power plants. They burn fuel with oxygen to release heat energy, which boils water and drives a steam turbine. This is majorly the one used by coal and oil plants. Natural gas uses a different process.

Conventional CoalFired Power Plant an overview ScienceDirect

It offers a radically different approach to the problem. A conventional coalfired power plant with postcombustion capture has to separate carbon dioxide from a flue gas mixture in which there is a large amount of nitrogen. The oxyfuel process, by removing the nitrogen at the start, so that coal burns in oxygen instead of air, sidesteps this ...
