What is the purpose of oxygen treatment in a boiler system?

The purpose of oxygen treatment in a boiler system is to form a protective oxide layer on the internal surfaces of the boiler. This protective layer helps prevent corrosion by insulating the metal surfaces from direct contact with the water and any dissolved gases, including oxygen. When water is heated in a boiler, oxygen can lead to oxidative corrosion, resulting in pitting and degradation of the metal over time. By introducing a controlled amount of oxygen, a stable oxide layer can be created, which significantly enhances the durability and lifespan of the boiler components.

In a well-managed system, maintaining proper oxygen levels can improve overall efficiency, reduce maintenance costs, and enhance the safe operation of the boiler. This treatment is crucial in facilities where boiler reliability is critical, as it contributes to the long-term health of the system.
