FIXED NOZZLE DESUPERHEATER
A fixed nozzle desuperheater utilizes high performance fixed geometry nozzles to reduce the steam temperature by directly injecting water inside the superheated steam flow. The spray water quantity is controlled by an external control valve which responds to feedback from a controller and downstream temperature sensor.
Variable nozzle desuperheaters are best suited for applications involving high load fluctuations. They are designed to control the quantity of spray water at the point of water injection, thereby eliminating the need of a separate water control valve. This is achieved by coupling the desuperheater with an actuator and subsequently varying the number of injection nozzles in operation. Nozzle opening is controlled through precise positioning of the desuperheater stem in response to feedback from a controller and downstream temperature sensor.
