The efficiency of a conventional steam–electric power plant, defined as energy produced by the plant divided by the heating value of the fuel consumed by it, is typically 33 to 48%, limited as all heat engines are by the laws of thermodynamics (See: Carnot cycle). The rest of the energy must leave the plant in the form of heat.

A simplified diagram of a coal-fired thermal power station. The superheater is the element 19. In many applications, a turbine will make more efficient use of steam energy than a reciprocating engine. However, saturated ("wet") steam at boiling point may contain, or condense into, liquid water droplets, which can cause damage to turbine blades.
A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [1]
The water, held under high pressure to keep it from boiling, produces steam by transferring heat to a secondary source of water. The steam is used to generate electricity. Cooling water from the river condenses the steam back into water. The river water is either discharged directly back to the river or cooled in the towers and reused in the plant.
The steam turbine operates on basic principles of thermodynamics using the part 3-4 of the Rankine cycle shown in the adjoining diagram. Superheated steam (or dry saturated steam, depending on application) leaves the boiler at high temperature and high pressure. At entry to the turbine, the steam gains kinetic energy by passing through a nozzle ...
It is recommended to name the SVG file “Diagram Submarine Reactor & Steam Plant.svg”—then the template Vector version available (or Vva) does not need the new image name parameter. This image was uploaded in the JPEG format even though it consists of non-photographic data .
Dry steam power directly uses geothermal steam of 150 °C or greater to turn turbines. [3] As the turbine rotates it powers a generator that produces electricity and adds to the power field. [ 26 ] Then, the steam is emitted to a condenser, where it turns back into a liquid, which then cools the water. [ 27 ]
