Menetelmä ja laitteisto lauhteen jäähdyttämiseksi ja sen lämmön talteenottamiseksi kattilalaitoksessa

摘要

Method and an apparatus for cooling condensate in a boiler plant comprises a condenser (1), which is connected to a condensate cooler (3), through which a duct (4) branching off from a combustion air duct of the boiler is introduced to the boiler. The condensate cooler (3) has a direct heat and mass transfer connection between combustion air and condensate, for cooling the condensate and for heating and moistening the combustion air. A discharge duct (5) for the condensate extends from the condensate cooler (3) for discharging the cooled condensate from the boiler plant.
