METHOD OF THERMAL DEAERATION OF WATER Russian patent published in 2003 - IPC

FIELD: heat- power engineering+ADs- boiler plants and thermal power stations. SUBSTANCE: proposed method includes deaeration of water under excessive pressure and removal of steam formed in the course of deaeration followed by cooling steam in cooler by starting water fed to deaerator+ADs- noncondensable gases are evacuated from steam cooler into atmosphere. Steam is cooled by mixing it with starting water fed to deaerator+ADs- consumption of steam and pressure in deaerator are regulated by means of regulating unit fitted on pipe line discharging noncondensable gases into atmosphere. Mixture of steam condensate and starting water is directed to upper part of deaeration column. EFFECT: enhanced reliability and economical efficiency. 1 dwg
