Description
Superheater
Superheaters are heat exchangers located in the upper part of the furnace that bring the steam to its live operating temperature with heat transfer occurring both by convection and radiation.
Reheater
Power plant furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.
Function
Superheater is to increase the temperature of the steam above its saturation point.
Reheater is basically a superheater that superheats steam exiting the high-pressure stage of a turbine. The reheated steam is then sent to the low-pressure stage of the turbine. By reheating steam between high-pressure and low-pressure turbine it is possible to increase the electrical efficiency of the power plant cycle beyond 40%.The reheat cycle is used in large power boilers since it is feasible economically only in larger power plants.

Application
Related Industry: Power Generation
The steam superheater aids in the drying of process steam. To maintain optimal performance of the system water vapor must be removed from the steam turbine system.
