PRESSURE REDUCING & DESUPERHEATING VALVES (PRDS) - The most advanced method to reduce pressure and temperature of steam in a single unit, called a "Combined PRDS". - During the process of pressure reduction in the valve, water is simultaneously injected into a highly turbulent zone, called the "Vena Contracta". - This causes instantaneous evaporation of water for complete desuperheating. - c/w pneumatic actuator with emergency handwheel & EP positioner Pressure Reducing & Desuperheating Station DESUPERHEATER - VARIABLE NOZZLE & FIX NOZZLE - The most practical way of reducing the superheat value of steam is by direct addition of water. - To achieve temperature stability of the conditioned steam and prevent thermal shock in downstream pipes, cooling water must be atomized. - It is also necessary to have a correct mix of superheated steam and cooling water. - Common models are Fixed Nozzle Desuperheater (FND) and Variable Nozzle Desuperheater (VND).
