摘　　要：以往凝汽器喉部补偿节设计方案常常通过4排支撑钢管进行加固,考虑到多排支撑钢管结构可能产生较大的喉部汽阻的问题,提出一种新型补偿节单排钢管支撑优化结构和一种双排支撑钢管优化结构,以期降低凝汽器整体汽阻,换热性能更佳。In the previous design scheme of condenser throat compensation joint,it is often reinforced by four rows of support steel tubes.Considering the problem that multiple rows of supporting steel pipe structures may generate larger throat vapor resistance,a new type optimal structure of single row steel pipe supporting and a double row of supporting steel pipefor compensation joint are proposed to reduce the overall vapor resistance of the condenser.Heat transfer performance is improved.
