Steam Desuperheater is used to spray water into steam so that water get mixed with steam resulting in reduction in the temperature of the outlet steam. Desuperheater can be classified into two
1. Non-Integral type Desuperheater
Desuperheater nozzle and water valve are separate units
2. Integral type Desuperheater
Desuperheater is in-built with actuator so that there is no need to separate spray water valve
1. Venturi type
Nozzle orifice is fixed irrespective of flow variation
2. Variable orifice
Orifice area opening will vary according to the flow and pressure variations
