马头发电总厂＃8炉再热器改造

Modification of Reheater of Boiler No.8 in Matou Power Plant

针对马头发电总厂# 8炉再热蒸汽温度偏低的问题 ,参考锅炉热力计算结果 ,确定了在转向室增加低温再热器受热面的改造方案 ,并在机组大修中实施。改造后锅炉运行情况表明 ,主、再热汽温完全达到设计值 ,且有一定的调整裕量 ,机组的经济性和安全性提高 。

In view of the low reheated steam temperature problem of Boiler No. 8 in Matou Power Plant, and based on the thermo-dynamic calculation of the boiler, the heat surface of low temperature reheater are added in the flue turning area. After this modification in an overhaul, the temperatures of main and reheated steam both recovered up to the design values with certain regulating margins. The economic and safety performance of the unit improved, and the modification is successful.
