The action texture of boiler deoxidizer

Boiler deoxidizer  is a chemical agent used to remove oxygen from boiler water, and its mechanism of action mainly includes the following aspects:

Oxidation-reduction reaction: Boiler deoxidizers often contain reducing agents such as sulfite or sodium sulfite. These reducing agents can undergo an oxidation-reduction reaction with oxygen in water, reducing oxygen to water. This can effectively reduce the oxygen content in boiler water.

Chemical complexation: Some components in boiler deoxidizers can undergo chemical complexation reactions with oxygen, forming stable complexes. These complexes are relatively stable and can block oxygen from entering the boiler system, reducing the corrosion and oxidation effects of oxygen on metal components.

Surfactant function: Boiler deoxidizers often contain surfactants such as glycidyl dialdehyde (HEDP), polycarboxylates, etc. These surfactants can form a protective film on the surface of water, reducing the rate of oxygen entering the water, thereby reducing the corrosion and oxidation effect of oxygen on metal surfaces.

Solubility of reaction products: After certain components in the boiler deoxidizer react, the resulting products have high solubility. These products can maintain a dissolved state in water without forming insoluble precipitates, thereby reducing the accumulation of precipitates and blocking pipelines.

It should be noted that different types of boiler deoxidizers have different mechanisms of action. When using boiler deoxidizers, appropriate deoxidizers should be selected based on the specific boiler type, water quality conditions, and operating requirements, and the correct dosage and control should be carried out according to the instructions for use. At the same time, regularly inspect and maintain the water quality of boiler water to ensure the normal operation and safety of the boiler system.
