| 摘 要： | 对合成氨新工艺二段转化炉后废热锅炉炉管运行情况进行分析，指出在运行过程中，因磷酸在钠在特定的环境中，在高温条件下，转化为焦磷酸钠或六偏磷酸钠，使炉水变为酸性，造成炉管酸性腐蚀。

| Abstract: | This paper analyses the operation of waste heat boiler tubes downstream the secondary reformer.It is pointed out that during the operation at high temperature in specific surroundings,the Na3PO4 shifted into(NaPO3)6 which turned the boiler water to acidic,resulting in the acid corrosion of boiler tubes. |
