摘　　要：介绍了中石化普光气田天然气净化厂12套硫磺回收单元克劳斯反应炉废热锅炉的结构及内衬施工过程。废热锅炉除陶瓷套管及刚玉浇注料外全部国产化。在试车烘炉中废热锅炉第一段入口端陶瓷套管大面积开裂,后采用进口材料和国产材料2套修复方案加以处理。实践证明,采用国产锆刚玉陶瓷套管及刚玉浇注料修复后废热锅炉运行稳定。目前废热锅炉已运行4年时间,预计使用寿命可超过6年。The structure and lining construction process of waste heat boiler equipped with Claus reactor in 12 sulphur recovery units of SINOPEC Puguang gas field natural gas purification plants are introduced. The waste heat boilers were localized except for ceramic tube ferrule and corundum castable. The ceramic tube ferrule cracked severely at the inlet of the 1 st waste heat boiler during trial run. Then two restoration with domestic and imported materials were adopted respectively. Practice confirmed that the waste heat boiler ran stable after using domestic zircon corundum ceramic tube ferrule and corundum castable. So far the waste heat boiler has been op- erating smoothly for 4 years. It＇s predicted that the service life will exceed 6 years.
