Difference between Open and Closed Feedwater Heaters

The energy used to heat the feedwater is usually derived from steam extracted between the stages of the steam turbine. Therefore, the steam that would be used to perform expansion work in the turbine (and therefore generate power) is not utilized for that purpose. The percentage of the total cycle steam mass flow used for the feedwater heater is termed the extraction fraction and must be carefully optimized for maximum power plant thermal efficiency since increasing this frac… WebIt is common knowledge in thermodynamics that Closed FeedWater Heaters (CFWH) do not directly mix the hot stream (bled from turbine) and cold stream (coming from the condenser via 1st pump),...
