对华能海门电厂2台1036MW机组冷端系统在循环水泵双速改造前后进行了运行优化试验,根据试验数据拟合出汽轮机背压和功率微增曲线及汽轮机功率修正计算公式,并计算出了凝汽器变工况特性;采用综合煤价和电价比较法得出循环水泵双速改造前后的推荐运行方式。实践证明循环水泵双速改造后能达到进一步节能的目的,使电厂获得了最大的经济效益。
The operation optimization test of two 1036MW unit cold end systems in Huaneng Haimen Power Plant before and after the double-speed reformation of circulating water pump was carried out. According to the test data, the formula of turbine backpressure and power increase curve and steam turbine power correction were calculated, and the condensate The characteristics of the steam turbine change the working conditions; The comprehensive coal price and the electricity price comparison method draws the circulation pump two speed before and after the transformation of the recommended operating mode. Practice has proved that after the transformation of two-speed circulating pump can achieve the purpose of further energy saving, so that the power plant has been the greatest economic benefits.
