  • BOILER WATER TREATMENT AND CONDENSATE RETURN …

    If soda ash is used for boiler water treatment it too breaks down in the boiler to form caustic soda and carbon dioxide. This simply increases the corrosion problem, and, if you are using a neutralizing amine it increases your cost. Inasmuch as caustic soda is already reverted to the final pro-duct, no carbon dioxide is given off in the boiler.Learn More
