摘　　要：宁夏电力投资集团西夏热电厂200 MW供热机组在冬季采暖工况下,改变冷却塔的运行方式由双塔切换至单塔运行,降低了厂用电率,减小了凝汽器的端差,降低了冷却塔的补水量,避免了冷却塔的大量结冰,水耗明显降低,达到机组节能目的。Ningxia Electric Power Investment Group in Xixia thermal power plant 200 MW unit in winter heating condition, change the mode of operation of the cooling tower by the twin towers switched to single tower operation, reduce the auxiliary power consumption rate, reduce the difference of the condenser end, reducing the cooling tower of water supply, to avoid the cooling Tower of a large number of ice, water consumption decreased significantly, to achieve the purpose of energy saving unit.

关 键 词：单塔运行 水耗 端差 厂用电率
