摘　　要：通过对神华内蒙古国华呼伦贝尔发电有限公司某超临界600MW空冷机组主要运行经济指标现状的分析,依据能耗诊断方法,研究影响机组运行经济性的主要因素,经定量计算这些因素对机组经济性指标的影响量,得出机组能耗损失的分布及其主要原因,据此,提出了该机组的节能降耗措施,并定量计算了该措施的预期效果,其中发电煤耗下降约10.7g/(kW·h),厂用电率下降约1.32百分点。部分措施实施后,机组发电煤耗下降约6.1g/(kW·h),厂用电率下降约0.27百分点,折算机组供电煤耗下降约7.2g/(kW·h)。Investigation on current situation of major operation economic indices of a supercritical 600 MW air cooling unit was conducted.The energy consumption diagnosis method was employed to analyze the main factors affecting the unit operation economy,and quantitatively calculate the influence amount.The unit energy loss distribution and its reasons were concluded.Therefore,countermeasures for energy saving for this unit was put forward,and calculation showed the expecting results were:coal consumption for power generation can be decreased by about 10.7 g/(kW·h),and the auxiliary power consumption rate by about 1.32%.After part of the measurements were put into service,the coal consumption for power generation dropped by about 6.1 g/(kW·h),the auxiliary power consumption rate by about 0.27%,and the converting coal consumption for power supply by about 7.2 g/(kW·h).
