Deaerators are normally used in any Chemical Process Industry or in Power Plants where boiler is employed for steam production from boiler feed water. Deaerator solves the purpose of removal of unwanted dissolved gases and dissolved oxygen from the boiler feed water before entering into boilers. Most of the deaerators are designed in such a way that the dissolved oxygen content in the outlet water is about 7 ppb by wt.%
Advantages of Deaerator
Deaerator acts as an additional storage device which provides reserve quantity of boiler feed water during upstream water supply failure for momentary periods normally for about 20 minutes. In some of the Plants, Deaerator is also used for dosing oxygen scavenging chemicals like Hydrazine or Hydroquinone.
