摘　　要：影响凝结水过冷度的因素有很多,从低压加热器疏水对凝结水过冷度影响进行研究,揭示出运行中过冷度为负值的原因,为设计阶段合理确定凝汽器热井疏水排放点的位置奠定了理论基础。There are many factors that can influence the condensate sub-cooling degree, from the low-pressure heater drain effect on condensate sub-cooling degree to study, the negative reasons while running is revealed, which lay a theoretical foundation for the location of the drain discharge point of condenser hotwell in the design phase.

关 键 词：汽轮机 低压加热器 凝结水过冷度
