The process of burning coal in a boiler to create steam is how coalfired power plants generate electricity. Under extreme pressure, the steam produced enters a turbine, which turns a generator to produce electricity. In order to restart the process, the steam is then cooled, condensed back into the water, and fed back into the boiler.
