上海外高桥电厂2号机组汽轮机锅炉给水泵经优化后,机组的经济性可以相对提高0.4％～0.65％,对于配置2×50％容量汽动给水泵和1×50％电动调速备用给水泵的300MW机组,建议泵组的最佳运行范围为:在300～180MW之间,采用2台汽动泵并联运行的方式;在小于180MW负荷时,则可以采用单台汽动泵运行及电动泵备用的方式。本文提出的锅炉给水泵优化运行试验方法同样适用于国产引进型300MW机组给水泵。
After the optimization of the boiler feed water pump of Shanghai Waigaoqiao Power Plant Unit 2, the economic efficiency of the unit can be increased by 0.4% -0.65%. For 2 × 50% capacity steam feed water pump and 1 × 50% electric speed control backup Pump 300MW unit, it is recommended that the best pump operating range: 300 ~ 180MW, the use of 2 sets of steam pump in parallel operation; less than 180MW load, you can use a single steam pump operation and electric Pump backup method. This paper puts forward the optimal operation of boiler feed pump test method also applies to imported 300MW unit feed pump.
