| 摘 要： | 以费县电厂600MW机组为背景, 分析影响电厂经济性的因素。认为煤质、锅炉效率( 排烟损失、不完全燃烧) 、汽机效率( 节流损失、初蒸汽参数、凝汽器背压、给水温度、系统泄漏、通流间隙调整) 、厂用电率是提高电厂节能水平的主要项目。针对每一项目提出了解决措施。

| Abstract: | Using 600 MW units in Feixian Power Plant as an example,this paper analyzes factors that affect power plant economic operation.It suggests that coal quality,boiler efficiency(flue gas emission loss,inadequate combustion),steam turbine efficiency(throttle loss,initial steam parameters,condenser back pressure,feed water temperature,system leakage,through flow clearance adjustment),and auxiliary power consumption are keys to improve power plant energy saving.And solutions to each factor are presented. |

| Keywords: | thermal power plant energy saving coal quality system efficiency auxiliary power consumption |
