Pressure Reducing & DeSuperHeating Systems (PRDSH) :
PRDS Systems are designed to reduce the steam pressure to operating pressure. It also brings the outlet steam temperature closer to that of saturation.
The pressure reducing valve installed on super heated steam line are suitably designed which reduces steam pressure to desired operating pressure. During this process the steam temperature also reduces following superheat remains unaltered.
The steam temperature is reduced close to saturation by injecting water into high velocity steam by controlled water flow through water control valve.
Conventionally steam pressure reduction and temperature reduction were done in two different units. Now both this functions are carried in one unit which is a combined pressure reducing and desuperheating valve. |

De-Super Heating System (DSH) :
The purpose of DeSuperHeating systems are to reduce the temperature of super heated steam close to that saturated temperature.
The steam temperature is reduced close to saturation by injecting water into high velocity steam by controlled water flow through water control valve. |
