How Coal Power Plants Produce Electricity. The heat from combustion of the coal boils water in the boiler to produce steam. In modern power plant boilers produce steam at a high pressure and temperature. The steam is then piped to a turbine. The high pressure steam impinges and expands across a number of sets of blades in the turbine.
Higher efficiencies mean that less fuel is used to generate the rated power resulting in lower costs and the formation of fewer greenhouse gases. For example a 60 percentefficient gasification power plant could cut the formation of carbon dioxide by 40 per cent compared to a typical coal combustion plant.
