摘要
针对催化裂化装置余热锅炉普通省煤器存在严重的露点腐蚀问题 ,结合热管特性开发了夹套式热管元件 ,研制出抗露点腐蚀热管省煤器 ,提高了管壁温度 ,消除了“局部冷区” ,避免了发生露点腐蚀。夹套式热管省煤器用于 12 0万t/年催化裂化装置余热锅炉 ,克服了普通的省煤器露点腐蚀问题 ,跟踪测试其运行参数符合设计要求。图 3表 1参
With an eye on the serious dew point corrosion problem existing with general types of waste heat boiler economizers of catalyzing crocking installations, and making use of the special properties of heat pipes a leave type heat pipe element and a dew point corrosion resistant economizer, working with elevated wall temperature has been developed, which avoids the appearance of “locally cold zones” helpful in preventing dew point corrosion. figs 3, table 1 and refs 4
