What is Steam turbine?
[[File:Dampfturbine Laeufer01.jpg|thumb|Steam turbine]] A '''steam turbine''' is a [[machine]] that gets [[thermal energy]] from [[Pressure|pressurised]] [[steam]]. It uses the energy to do [[mechanics|mechanical]] work by [[rotation]]. It is usually connected to a [[Electrical generator|generator]] to produce [[electricity]]. The heat to produce steam comes from burning a fuel such as [[coal]], from burning trash in an [[incinerator]], from the waste heat of other industrial processes, from a [[nuclear reactor]], or from a natural source such as sunlight or geothermal heat. ==Sizes== There are many sizes of steam turbines, from small ones (less than 0.75&nbsp;[[Kilowatt|kW]]) for [[pump]]s and other devices, to larger ones (1,500,000&nbsp;kW) for producing electricity. ==Related pages== * [[Turbine]] * [[Steam engine]] [[Category:Machines]] {{sci-stub}}
