摘　　要：根据传统高温过热器的结构和材质,分析了其用于硫磺制酸余热回收装置上时烟气侧容易泄露的原因。介绍了优化后卧式圆筒形高温过热器的主体结构和方变圆接管结构,应用实践证明,该高温过热器减少了应力集中点,显著提高了热应力承受能力,从而解决了其烟气侧的泄露问题。From the perspectives of the structure and material of construction of the traditional high-temperature superheater,the causes are analyzed as to why the flue gas side is prone to leakage for application in a waste heat recovery system of a sulfur-burning sulfuric acid plant.The body structure and square-to-circular transition duct tie-in structure of the optimized horizontal cylindrical high-temperature superheater are examined.It is demonstrated through this application practice that the high-temperature superheater mitigates stress concentrations and significantly enhances the thermal stress resistance,thus addressing the flue gas leakage issue.
