大型电厂循环水联通运行技术措施与效益分析

Technology Measures and Benefits Analysis of Cycling Pumps United Operation at Large Scale Power Plant

嘉兴电厂一期机组因循环水暖流影响,将循环水改接由二期循环水提供,降低了循环水温度,提高了机组真空,确保了夏季工况机组带负荷能力。在运行操作中,制订合理的调整、监视措施,确保循环水联通方式下的机组可靠和经济运行。一期机组循环水取自二期供水后,进水温度下降、真空提高,机组供电煤耗下降明显,同时也获得了其他社会效益。

Due to the influence of circulating water warm flow in Jiaxing Power Plant, the circulating water was changed from the second phase circulating water supply, which reduced the circulating water temperature, increased the unit vacuum, and ensured the unit load capacity under summer conditions.In operation, reasonable adjustment and monitoring measures should be formulated to ensure reliable and economic operation of circulating water. After the circulating water of the first stage unit is supplied by the second stage, the inlet water temperature drops and the vacuum increases, and the coal consumption of the unit power supply decreases obviously, and other social benefits are obtained.
