Evaporator with separate condensate pre-heater

Evaporator with separate condensate pre-heater

Evaporator with separate condensate pre-heater

This lay-out utilizes all of the heat from the flue gases for heating the condensate. The condensate is heated in the condensate pre-heater. The heat source for the deaerator steam is the evaporator which produces a water/steam mixture.

Aside from the condensate pre-heater the system is identical to the evaporator without separate condensate pre-heater.
