Coalfired 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 the water, and returned to the boiler to start the process over.
1. Background and Motivation The total US CO2 emissions for 2006 were 5934 million metric tons (Mt). Of this, the electricity sector was responsible for 2344 Mt (%). Coalfired power plants produced 83% of the electricity sector's CO2 emissions, with most of the remaining emissions from natural gasfired power plants (EIA, 2007).

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.
A simplified layout of a thermal power station is shown below. Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station.
