Some boiler feed pumps are rated to operate at 400 degC water temperature, implying that they are fed from deaerator systems operating at pressures substantially higher than the 570 psia mentioned in dberner's response. Anyone have any comments about their experiences with deaerator operating...
A Deaerator operating at 570 psia would certainly be expensive, but operating at this pressure allows the process plant to remove several 80 barg pressure vessels from their system, so the overall cost impact is balanced to some extent. A small economiser could still be installed to bring the...
I am involved with the design of a new steam generating plant consisting of two 225 tph boilers with 102 barg and 320degC outlet steam condition. The main return condensate flow [Stream 1] from the associated process plant can be up to 240 degC, making up 85% of the boiler feedwater flow. The...
