| Abstract: | Aiming at the existing corrosion of chimney in wet FGD system of heating units of a heating supply company in Harbin, this paper expounds the working condition of the system after desulphurization reconstruction, analyzes the corrosion mechanism of single-tube reinforced concrete chimney, and proposes reconstruction plan for chimney corrosion. The practice proves that the chimney is in good working condition without leakage of flue and gas or break and drop of anticorrosion coating. |
