First, the coal is mined from underground and ground into a fine powder so that it burns more easily. Take a look at the rest of the process below in the diagram from Energy Explorer. Now that you have an idea about the process coal goes through to become electricity, watch this VIDEO to see an animation of how a coal fired plant works.

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United States was ...

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.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).

Coal drying experiments were performed with lignite and Powder River Basin coals to determine the effects of inlet air moisture level on the equilibrium relationship between coal moisture and exit air relative humidity and temperature. The results show that, for lignite, there is a slight dependence of equilibrium moisture on inlet humidity level.
