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.

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.

Coal power plants are still being built in some fastgrowing economies in Asia. China, India, Indonesia, and Malaysia headed the list last year. But even there, the ardor is fading. Take China. It built a reported 43,000 megawatts of new coal powerplant capacity last year, almost twice as much as the rest of the world put together.

The amount of coal received by power plants in the United States has largely declined over the past decade as coalfired electricity generation has fallen and many coalfired power plants have closed. However, slightly more coal was shipped to power plants in 2022 than in 2021 even though coalfired generation fell by nearly 8% in 2022.

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.
