The present invention comprises an apparatus and method for efficiently venting impurities from a heat recovery steam generator system by concentrating the impurities in a condensing deaerating vent lineand then venting a proportionately small amount of steam with a proportionately high concentration of impurities. The condensing deaerating vent lineis attached to a low pressure drum, and feed watermay be added to the upper portion of the condensing deaerating vent lineto improve condensation and conserve thermal energy.
