What are the deoxidizers for chemical boilers

Chemical boiler deoxidizer is a chemical agent used to remove dissolved oxygen from water in boiler systems. By removing dissolved oxygen, corrosion and oxidation of the boiler system can be reduced, and the efficiency and lifespan of the system can be improved. The following are some common chemical boiler deoxidizers:

Sulfate type deoxidizers: such as sodium sulfite, ammonium sulfite, etc. These agents can react with dissolved oxygen to form insoluble sulfate precipitates, thereby removing oxygen.

Reducing agent deoxidizer: such as sodium bisulfite, potassium bisulfite, etc. These agents can reduce oxygen to water and react with it to form sulfates.

Organic chelating agents such as citric acid, ethylenediaminetetraacetic acid (EDTA), etc. These agents can form complexes with dissolved oxygen, making it less easily absorbed by the boiler system, thereby achieving the effect of removing oxygen.

High temperature vulcanizing agent deoxidizer: such as sodium sulfide. These agents decompose at high temperatures to form sulfides, effectively removing oxygen.

It should be noted that the selection of appropriate chemical boiler deoxidizers should be based on the specific situation and requirements of the boiler system, including water quality, working temperature, pressure, etc. When using, the recommended dosage should be added according to the product manual, and safety operating procedures should be strictly followed to ensure safe use and good results. It is best to consult professional boiler water treatment technicians to obtain appropriate advice for specific systems.
