Boiler (power generation) - Wikipedia

Boiler (power generation) 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 (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator .

Steam Temperature Control | Control Notes

Sep 08, 2010· Steam Temperature Control. Modern boilers raise the steam temperature to around 1000F (538C), which approaches the creep (slow deformation) point of the steel making up the superheater tubing. Steam temperatures above this level, even for brief periods of time, can shorten the usable life of the boiler.

Thermal Efficiency of Steam Turbine - Nuclear Power

Thermal Efficiency of Steam Turbine. In modern nuclear power plants the overall thermal efficiency is about one-third (33%), so 3000 MWth of thermal power from the fission reaction is needed to generate 1000 MWe of electrical power. The reason lies in relatively low steam temperature (6 MPa; 275.6°C).
