How Does a Coal Power Plant Work?

In 1995, Coal burning produced about 55% of the electricity generated in the U.S. In addition, know coal reserves are expected to last for centuries at current rates of usage. Coal power is a rather simple process. In most coal fired power plants, chunks of coal are crushed into fine powder and are fed into a combustion unit where it is burned.

9.1.1. Carbon Dioxide Capture Approaches | netl.doe.gov

Post-combustion CO 2 capture is primarily applicable to conventional natural gas and pulverized coal-fired (PC) power generation. In a typical PC power plant, fuel is burned with air in a boiler to produce steam, which drives a turbine to generate electricity. The boiler exhaust, or flue gas, consists mostly of nitrogen (N 2), and CO 2.
