摘要

通过对神华国华电力公司宁海、绥中发电厂4台超超临界1 000MW机组的设备和系统及其主要运行经济指标的分析

研究影响机组运行经济性的主要因素

并定量计算这些因素对机组经济性指标的影响量。据此

提出了相应的节能措施

并定量计算出了该措施的预期效果。结果表明:宁海电厂5、6号机组发电煤耗均可下降约4.0g/(kW·h)

厂用电率均可下降约0.47%

折算供电煤耗均可下降约5.6g/(kW·h);绥中电厂3、4号机组发电煤耗可分别下降约2.8、2.6g/(kW·h)

厂用电率可分别下降约0.56%、0.55%

折算供电煤耗可下降约4.8g/(kW·h)。

Abstract

The equipments and systems and the main operation economic indices of four ultra supercritical 1000 MW units in Ninghai and Suizhong Power Plants of Shenhua Guohua Electric Power Company were analyzed to investigate the major factors affecting the unit operation economy and calculate the influence quality.Thus

the corresponding energy saving measures were put forward

and the expecting effects were quantatively calculated.For the No.3 and No.4 units in Ninghai Power Plant

the coal consumption for power generation can both be reduced by 4.0 g/(kW·h);the auxiliary power consumption rate can both be dropped by 0.47%;the converted coal consumption for power supply can both be decreased by 5.6 g/(kW·h).For the No.3 and No.4 units in Suizhong Power Plant

the coal consumption for power generation can be reduced by 2.8 g/(kW·h) and 2.6 g/(kW·h)

respectively;the auxiliary power consumption rate can be dropped by 0.56% and 0.55%;the converted coal consumption for power supply can both be decreased by 4.8 g/(kW·h).
