In power industries, steam is used to perform mechanical work, such as driving a turbine, and also as a heat transfer fluid. Both functions are accomplished with steam properties at opposite ends —dry superheated steam at high end, while de-superheated steam near its saturation point at the low end. Introduction of De-superheater can effectively improve the thermal efficiency of heat transfer processes by allowing the usage of steam at its saturation point, to control unintentional superheat from reducing the pressure of steam, to protect the boiler equipment and piping from high temperatures and pressures.
