Desuperheaters

Desuperheater
Desuperheaters reduce the temperature of superheated steam to its saturation point for optimal heat transfer and efficiency.
In many manufacturing processes, steam is initially superheated and distributed at high-pressure to prevent the formation of condensate droplets. In the case of turbine applications, droplets can cause significant damage to turbine blades. In downstream applications cooler steam is needed. Desuperheaters inject cooling water to cool the steam to its saturation point for optimum heat transfer in these applications.
