The inverted U-tube bundle of a Combustion Engineering steam generator. 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.It is used in pressurized water reactors (PWRs), between the primary and secondary coolant loops. It is also used in liquid metal cooled reactors (LMRs), pressurized ...
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884.
Turbine - Steam, Technology, History: The first device that can be classified as a reaction steam turbine is the aeolipile proposed by Hero of Alexandria, during the 1st century ce. In this device, steam was supplied through a hollow rotating shaft to a hollow rotating sphere.
A steam turbine is a machine that gets thermal energy from pressurised steam. It uses the energy to do mechanical work by rotation. It is usually connected to a generator to produce electricity.
The steam generator is a key energy transfer device connecting the primary and secondary loop systems of nuclear reactor. According to the fluid flow mode of secondary loop in the steam generator, the steam generators of pressurized water reactor can be divided into the natural circulation type and the once-through type (Yan and Cao, 2010)。 (1)
1 sty 2008 · This dissertation shows that the architecture of steam generators, steam turbines and heat exchangers for power plants can be predicted on the basis of the constructal law.
