河南新乡电厂 4 4 0t/h循环流化床锅炉在调试运行初期 ,出现过热蒸汽、再热蒸汽超温现象。分析其原因是过热器和再热器受热面吸热面积设计太大 ,减温水流量设计太小。经过对减温器进行改造和减小再热器受热面面积 ,超温问题得到了解决
Henan Xinxiang Power Plant 4 4 0t / h circulating fluidized bed boiler in the commissioning of the initial run, there overheated steam, reheat steam over-temperature phenomenon. Analysis of the reasons is superheater and reheater heating surface heat absorption area design is too large, the design of water flow is too small. After the desuperheater to transform and reduce the reheater heating surface area, over-temperature problem has been solved
