Explained: How Does a Deaerator Work? - Boiler Water Treatment

· The amount of steam required to heat and deaerate the makeup water including vented steam depends on the amount of incoming water and its temperature Generally the inlet feed water temperature must be at least 20deg F(11 deg C) below the deaerator steam temperature for proper Deaeration in spray-tray design and upto 50 deg F(27 deg C) in spray only design
