Boiler (power generation) An industrial boiler, originally used for supplying steam to a stationary steam engine. A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low ...
A steam generator is a form of low water-content boiler, similar to a flash steam boiler. The usual construction is as a spiral coil of water-tube, arranged as a single, or monotube, coil. Circulation is once-through and pumped under pressure, as a forced-circulation boiler. [1] The narrow-tube construction, without any large-diameter drums or ...
Heat recovery steam generator. A heat recovery steam generator ( HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream, such as a combustion turbine or other waste gas stream. It produces steam that can be used in a process ( cogeneration) or used to drive a steam turbine ( combined cycle ).
Thermal power station. A thermal power station is a type of power station in which heat energy is converted to electrical energy. In a steam-generating cycle heat is used to boil water in a large pressure vessel to produce high-pressure steam, which drives a steam turbine connected to an electrical generator.
The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam-electric power plants is ...
Contents. Timeline of steam power. Steam power developed slowly over a period of several hundred years, progressing through expensive and fairly limited devices in the early 17th century, to useful pumps for mining in 1700, and then to Watt's improved steam engine designs in the late 18th century.
A steam generator (aka nuclear steam raising plant ('NSRP')) is a heat exchanger used to convert water into steam from heat produced in a nuclear reactor core. They are used in pressurized water reactor between the primary and secondary coolant loops. In typical PWR designs, the primary coolant is high-purity water, kept under high pressure so ...
A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power . In contrast to a subcritical boiler in which steam bubbles form, a supercritical steam generator operates above the critical pressure – 22 megapascals (3,200 psi) and temperature ...
