Through comprehensive stress calculation of outlet header of high-temperature superheater,the stress defects during operation are found out,and shortages in boiler design are pointed out,at the same time,and the ultimate causes of crack between header and snake tubes are found.

通过对高温过热器出口联箱进行综合应力计算,查明设备运行过程中存在的应力缺陷,指出了锅炉设计中存在的不足,同时也找出了联箱与蛇形管根部开裂的根本原因。

The CAD system of snake tube is designed according to the snake tube design rule, and introducing Visual C++ 5.

针对锅炉行业产品设计需要,依据蛇形管设计规则,采用Visual C++5。

The manufacturing technology of coiled tube in foreign utility boiler works was introduced, and its comparison with domestic manufacturing technology was carried out.

介绍国外几家电站锅炉制造厂蛇形管制造工艺，并同国内的制造工艺进行简要比较。

This paper introduced that part of superheater tube of JG-65/3.

82-450 M循环锅炉由于安装煮炉不慎造成部分过热器蛇形管堵管,加上用户自配水处理钠离子交换器等参数不匹配造成结垢,通过现场分析要重新换管,改进水处理后,锅炉正常运行。
