低压加热器疏水泵在机组启停中替代凝结水泵的节能效果分析

The energysaving effect analysis of replacing condensate pump by drain pump of low pressure heater at starting and shutting process of unit

介绍了低压加热器疏水泵和凝结水泵的技术特点,对2种泵的技术参数进行了比较,进而提出了低压加热器疏水泵替代凝结水泵的改造方案。改造后的低压加热器疏水泵节能效果良好。

The technical characteristics of drain pump of low pressure heater and condensate pump were described, and their technical parameters were compared each other, then a reformation plan was put forward which demands replacing the condensate pump by drain pump at starting and shutting process. The energy-saving effect is notable after the reformation realized.
