| 摘 要： | 南热2×600 MW超临界机组自投运以来排烟温度一直居高不下。分析了1号机组空气预热器进、出口运行参数,指出空气预热器的传热效果较低是其主要原因,综合比较了3种改造方案,最终采取方案一,即更换热端传热元件板型对空气预热器进行了改造。运行结果表明,锅炉排烟温度降低约10℃,提高了传热效果和锅炉效率。

| Abstract: | The exhaust gas temperature of two 600 MW supercritical power plants has always been too high since they were put into operation.After analyzing the operational parameters of the air preheater in #1 power plant,this paper figures out that the poor heat transfer performance is the main reason.Three reform schemes are compared,and Scheme 1,which means to change the type of heat transfer components,is finally adopted.The operation results show that the exhaust gas temperature has been decreased by 10 ℃,and a better boiler efficiency has been obtained. |
