Water Handbook - Boiler Feedwater Deaeration | SUEZ

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. Because the solubility of oxygen in water is very low under these conditions, 97 to 98% of the oxygen in the incoming water is released to the steam and is purged from the system by venting.

Reverse Osmosis Improves Boiler Efficiency – Water …

16/1/2017 · To maintain the conductivity at 4000 micromhos/cm, the boiler must have a blowdown rate of 5% of the feedwater; in this case, just under 4 gallons per minute (5,750 gallons per day). A major advantage of reverse osmosis over traditional softening is that it removes 99% of the dissolved solids from the makeup.
