Feedwater Heater Vent sizing
Feedwater Heater Vent sizing
(OP)
I'm looking for a rational explanation of the orifice sizing for the operating vent of feedwater heaters. I have seen sizing criteria stated as 0.5 to 1.5 % of extraction steam flow but I don't know where it comes from. HEI doesn't have a criteria that I could find.
