Abstract
The corrosion of the hot water supply system in a thermal power plant in Baotou was analyzed.Results showed that corrosion of the inner surface of pipe was oxygen corrosion,the main influencing factor were DO(dissolved oxygen) and pH value.In order to solve the corrosion problem, a new compound corrosion inhibitor with Sodium erythorbate as the main component was proposed. Due to synergistic effect exists amongthe components of the compound ihibitor,therefore, the inhibitor can effectively enhance the resistance of the steel pipesto the corrosive softened waterin the system. The corrosion rate of carbon steel may be lowered to only 0.0303 mm/a with a dose of 150 mg/L inhibitor for the soften water with pH 10.
