Coal and oilfired process. Coal and oilfired steam power plants have steam turbines to convert the heat energy of combustion into mechanical energy, which then operates an electric generator. All plants use the steam turbine for the drop between the high pressure and temperature of the steam and the lower pressure of condensing vapor.

Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
