pressurizing deaerator
(OP)
Dear All
I want to know that why deaerator is pressurized. In my plant it is pressurized to 2.5 kg/cm2. what will happen if we pressurize it to 1.5 kg/cm2. Please give your inputs

Oxygen solubility in water decreases with temperature. So it is better to have a higher boiler feed water / condensate temperature. However, higher temperature would lead to boiling of the boiler feed water / condensate. That would decrease the stripping action of the steam. The de-aerator is operated under some pressure just to increase the boiling point of water at the same time keeping it at a higher temperature.
