Combined Steam Conditioning Valves (CSCV) offer both pressure reduction and the desuperheating process in a single unit. This application involves injection of cooling water into a highly turbulent zone soon after pressure reduction, resulting in thorough mixing of cooling water with superheated steam. Injected water breaks into infinitely small particles both with the help of pressure and velocity differentials between steam and water. This results in a quick evaporation of injected water.
CSCV’s are particularly popular as they do not have a traditional bypass arrangement and are a compact device in which pressure reduction and desuperheating can take place simultaneously.
