摘　　要：通过汽轮机、凝汽器变工况计算相结合可以得到不同机组负荷、不同循环水进口温度下循环水泵的机组负荷切换点。在凝汽器变工况时,两台循环水泵可以灵活改成一台运行方式,合理调节循环水量,使机组在最佳真空下运行。The quantity of water available can be changed to obtain the energy-conserving result. When the burden and temperature of cooling water is different the water circulating pump of a burden of machine can be get the cut over point through combining the varying operating mode of steam turbine and condenser together, the quantity of water circulating pump can be changed from two to one in order to change the quantity of water available for the best vacuum.

关 键 词：凝汽 循环水泵 变工况 最佳运行
