径向热管省煤器工作原理与在硫酸装置中的应用

The Operating Principle and the Application of the Radial Hot Tube Economizer for the Sulfuric Acid Plant

针对硫酸装置使用的分离套管式热管省煤器 (废热锅炉 ) ,被加热的水易漏入含SO2 烟气中 ,造成设备腐蚀、系统停车。介绍了径向热管的工作原理 ,分析了径向热管省煤器的特点。实践证明径向热管省煤器运行可靠性高、传热性能好、占地面积少 ,并列出其有关技术参数。

For the separated jacket hot tube economizer( waste heat boiler),it is easy for the heated water to leak into the gas containing SO 2,which will lead to corrosion of equipment and system shut down.It introduces the operating principle of the radial hot tube and analyzes the feature of the radial hot tube economizer.The practice shows that the radial hot tube economizer has higher operation reliability and good heat transfer property and its occupation area is less,and the related technical parameters are listed in the article.
