Hello. My question is about control / reducing valve between economiser and a drum in HRSG, which is used in every HRSG to avoid steaming of water entering the drum. I need an information if this valve:
- is "open" at nominal conditions (design performance), so there is no pressure reduction, and water enters the drum at the temperature a little bit lower than the saturation temperature for the pressure in the drum as a result of proper dimensioning the economiser, or
- there is a pressure reduction even at nominal conditions
Thanks for reply.
