A stream of heating steam 9 comes in through a heating-steam entry 22 of the deaerator 21 and flows into a space above the tray 24 and under the perforated distributing tray 23; the steam flows down together with feedwater 3 along the tray 24 in a manner of parallel flow; the feedwater 3 is in contact with the heating steam 9 as the feedwater flows down, some of it along the tray 26 and the rest falling into the passageway for steam through holes in the tray 26; through this downward flow the teedwater 3 undergoes deaeration at the secondary stage. The downward flow of feedwater in a deaerator in this manner is not blocked and is free from flooding therein.
