加热炉对流炉管的低温露点腐蚀

Corrosion of the Convective Pipes of Heater by Low Tempreture and Dew point

通过分析腐蚀的形成和影响因素,以及腐蚀速度与管壁温度的关系,对提高炉管管壁温度、设置空气预热器、开发耐热耐蚀金属材料及炉管表面处理等具体防腐措施进行了讨论。

Based on analyzing corrosive formation and influencing factor and the relation between corrosion velosity and pipewall tempreture, the paper discusses such specific measures of corrosion protection as tempreture increasement of pipewall, installation of air preheater , development of heat-resisting and corrosion-resisting metal material and treatment of piping surface, etc.
