  • Water Handbook - Boiler Feedwater Deaeration | SUEZ

    only a small quantity of steam must be vented, because most of the steam used to scrub the water is condensed and becomes a part of the deaerated water. In order to deaerate the boiler feedwater, water is sprayed into a steam atmosphere. This heats the water to within a few degrees of the temperature of the saturated steam.Get Price
