| Abstract: | Through investigation and analysis of practical operation status, the authors determine the direct reason of water wall burst is hydrogen damage. Moreover, the author point out that the main reason is alkali corrosion under the condition of medium concentration caused by waste blowdown obstruction. The main reasons of alkali corrosion are found and relevant countermeasores are presented. |
