Steam turbine: Parts, Types, Working, Diagram [With Pdf]
A steam turbine produces shaft power by means of an enthalpy drop of steam. A special feature of steam turbines is their ability for very high power, due to the big enthalpy drop realisable per steam mass unit. Supply conditions in modern coal-fired electric power stations come to about 250 bar (25 MPa), 565 °C (supercritical).
