METHOD OF THERMAL DEAERATION OF FEED WATER AT THERMAL POWER STATION

摘要

FIELD: heat-power engineering. SUBSTANCE: make-up feed water is deaerated in open-type deaerator, after which it is fed to feed water deaerator where increased pressure is maintained. Flash steam of deaerator is evacuated from it and is cooled down. Flash steam of high-pressure deaerator is cooled by mixing it with part of make-up feed water which is directed to open-type deaerator for repeated deaeration. EFFECT: higher efficiency.
