15-01-2019· Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.
While the temperature of the steam in the superheater rises, the pressure of the steam does not and the pressure remains the same as that of the boiler. Almost all steam superheater system designs remove droplets entrained in the steam to prevent damage to the turbine blading and associated piping. View chapter Purchase book

Radiant superheaters are the type of superheaters that are installed in a radiation zone just after the furnace. In high-pressure boilers when the temperature difference in saturated and superheated steam is around 100oC. Superheaters must be installed in a radiant zone.
02-05-2020· The superheater is one component in the boiler that serves to further heat the steam to produce steam that meets the requirements for turning turbines. The superheater is a collection of boiler pipes located in the flow of hot gas from combustion.
The saturated steam from the boiler or evaporating drum is drawn by steam circulating pump and is passed through the radiant superheater and then convective superheater. About 35% of steam coming out from the superheater is supplied to high pressure turbine.
A convection superheater is located in the convective zone of the furnace usually ahead of economizer (in the path of the hot flue gases). These are also called primary superheaters. A separately fired superheater is a superheater that is placed outside the main boiler, which has its own separate combustion system.
The sealed ultra-high-pressure circuit ran at between 1,200 and 1,600 psi (8.27 and 11.03 MPa), depending on the rate of firing. The HP boiler worked at approx 850 psi (5.86 MPa), and the low-pressure boiler at 200 to 250 psi (1.38 to 1.72 MPa).
