Oxygen attack in boilers - Lenntech

Boiler water DO removal Dissolved Oxygen removal from any steam and water system is of major importance. The first step is typically mechanical deaeration which is economical and serves to also eliminate other corrosive gases such as ammonia and carbon dioxide. A properly operated deaerator can reduce dissolved oxygen to as low as 10 µg/L (10 ppb).

Boiler Corrosion | Marinerspoint

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.

Dissolved Oxygen (DO) the primary corrosive agent of steam-generating systems is one of the most important water quality parameters to control in a boiler system. Improper water quality management can thus result in inefficiency costly repairs and downtime.

This is achieved by keeping a controlled level of alkalinity in the boiler at all times, and by removing oxygen by de-aeration in the boiler feed tank. In most cases an oxygen scavenger will also be used. The most common types of oxygen scavenger are sodium sulphite and sodium bisulphite, other organic chemicals may also be used.

Oxygen is highly corrosive when present in hot water. Even small concentrations can cause serious problems: iron oxide generated by the corrosion can produce iron deposits in the boiler. Oxygen corrosion may be highly localized or may cover an extensive area. Oxygen attack is an electrochemical process that can be described by the following reactions

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 addition of which actually leads up to increased feed water TDS and longer blowdowns.
