purpose of oxygen in the boiler system

Deaerator – Purpose, Principle, Types, Process Control

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% Principle of Dearators. Dearator normally works based on the following
