How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

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.
There are about 1,400 coal- and oil-fired electric generating units (EGUs) at 600 power plants covered by these standards.They emit harmful pollutants, including mercury, non-mercury metallic toxics, acid gases, and organic air toxics such as dioxin.
