摘要

某电厂150 MW汽轮机组低压加热器(低加)疏水系统由于设计缺陷

如2号低加低负荷满水、低加凝结水温升小、六段抽汽管道振动、低加疏水泵出力不足等

对机组运行的经济性和可靠性造成了较大影响。通过对存在问题的分析并采取有效的改进措施

使得低加疏水系统在较好的方式下运行

机组运行的经济性和安全性大为提高。

Abstract

The design defects in drain system of low-pressure heater of 15 MW steam turbine unit in one power plant

such as the low-pressure heater no.2 fully filled with water at low load

small temperature rise of condensate in the low-pressure heater

vibration of extracted steam pipeline in sixth section

and insufficient output capacity of drain pump for the low-pressure heater etc.

affect more greatly the economic efficiency and reliability of the unit in operation.Through analysis of the existing problems and adopting effective improvement measures

the drain system of low-pressure heater can be in operation of more optimized mode

enhancing greatly the economic efficiency and safety of the unit in operation.
