摘要
某催化余热锅炉因省煤器炉管多次腐蚀穿透泄漏而停运维修,极大地影响了生产。对省煤器炉管的腐蚀原因进行分析探讨,腐蚀原因是换热器管壁温度不够且炉管末端结构缺隙共同造成。提出了结构改进和增设给水预热器等防腐蚀建议。
An exhaust boiler stopped running and was repaired because the pipes of economizer were corroded many times. The corrosion leakage of economizer was analyzed. The main reason was that the temperature of the heat exchanger was not high enough and the structure defect. Some protection proposals were suggested.
