Boiler Feedwater Deaeration: How To Keep Your Steam System

The solubility of oxygen in water is reduced as the temperature of the water increases. The dissolved oxygen content of water at 20 °C is 9ppm, at 60 °C is 5 ppm and at 90 °C is just under 2 ppm. At 100 °C the oxygen content is theoretically 0 ppm. The removal of oxygen by heating (e.g direct steam injection) reduces the requirement of expensive oxygen scavenging chemicals (most often sodium sulphite), the

Dissolved oxygen, or DO, is one of the most important water quality parameters to control in a boiler system. It is the primary corrosive agent of steam-generating systems. Even low concentrations of DO can be highly destructive, causing localized corrosion and pitting of metal system components.

The dissolved oxygen content should be maintained at a minimum but at no time should it exceed 0.007 mg/l. Sulfites. Sodium sulfite is generally used for the chemical removal of dissolved oxygen within the boiler water. To assure the rapid and complete removal of the oxygen entering the boiler feedwater system the concentration of sulfite in the boiler must be maintained at a minimum of 20 PPM (parts

The acceptable dissolved oxygen level for any system depends on may factors, such as feed water temperature, pH, flow rate, dissolved solids content, and the metallurgy and physical condition of the system. In general, the limit value of oxygen in make up water can be stared 0.10 mg/kg
