    Deaerator – Wikipedia

    Deaerator plant. A deaerator is a device that removes oxygen and other dissolved gases from liquids. Deaerators are commonly used to remove dissolved gases in feedwater for steam-generating boilers. Dissolved carbon dioxide combines with water to form carbonic acid that may cause further corrosion.

    Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam Oxygen and Carbon Dioxide are removed from the feed water by deaeration. The gases are then vented to the atmosphere.
