Feedwater Temperature Rise in a Deareator For Boiler Feedwater
Feedwater Temperature Rise in a Deareator For Boiler Feedwater
(OP)
Hello,
Is there a rule of thumb on how much temperature rise you would expect in a deaerator for boiler feedwater to and from the deaerator?
I'm assuming some of the heat from deaeration gets transferred to the incoming feedwater.
Thanks in advance.

When condensate return water is 227°F or above, it is returned directly to the deaerator storage tank. Any condensate
below 227°F must be deaerated. Incoming makeup water is typically in the range of 55-70 °F.
Released dissolved oxygen and carbon dioxide gases along with a negligible steam loss of approximately one tenth of 1% are vented out of the roof of the deaerator.
