METHOD FOR THERMIC DEAERATION OF WATER Russian patent published in 2004 - IPC

Abstract RU 2225571 C1

FIELD: thermic deaeration of water, possibly in boiler aggregates. SUBSTANCE: method comprises steps of deaerating water in vacuum deaerator due to feeding to deaerator initial water and heating agent; sustaining predetermined concentration of dissolved oxygen in deaerated water by successively controlling temperature and flowrate of heating agent; when concentration of oxygen exceeds predetermined value at first increasing temperature of heating agent and then, if necessary increasing its flowrate; when concentration of oxygen becomes lower than predetermined value at first decreasing flowrate of heating agent and then lowering temperature of heating agent. EFFECT: enhanced efficiency and reliability of boiler aggregate. 1 dwg
