Steam Superheater in Boiler: Role, Benefits, Types

Steam Superheaters in Industrial Boilers. The Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to dry steam, generated by a boiler.. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latent heat to convert water into steam while superheater utilizes only sensible heat to …

Super-Heaters, Economisers & Air Heaters - Primasonics

Superheaters. A superheater is a vital part of the a boiler system that is used to increase the overall efficiency of a thermal power plant. More specifically, it is a device which converts wet steam (saturated steam) into dry steam as dry steam contains more thermal energy. Dry steam is also less likely to condense within the engine cylinders
