Only with high pressure steam, the high temperature steam can be converted more efficiently to mechanical energy in the turbine according to Carnot's theorem. Technically, the term "boiler" should not be used for a supercritical pressure steam generator as no "boiling" actually occurs in the device.
generator, and other auxiliaries. The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. Through proper integration
below the normal operating pressure of steam-raising boilers. This leaflet applies to steam and high temperature hot water boiler plant (operating above 0.5 bar pressure and a temperature of 110 C). It describes a process which you, as a manager, can apply to
The reason lies in relatively low steam temperature (6 MPa; 275.6 C). Increasing the temperature of the steam can attain higher efficiency. But this requires an increase in pressures inside boilers or steam generators. However, metallurgical considerations place
Trevithick was the first to successfully use high-pressure steam (then known as "strong" steam). Until ca. 1800, the weakness of existing boilers coupled with the influence of James Watt had generally restricted steam boilers to very low pressures or "weak" steam.
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 to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Normal or "live" steam is produced at a boiler, steam generator, or waste heat recovery generator – whereas flash steam occurs when high pressure / high temperature condensate is exposed to a large pressure drop such as when exiting a steam trap.
