摘要

某厂2台机组一直存在启动过程中低压缸轴封温度偏低的问题。经过分析

供汽温度下降、管道疏水不畅是两大主要原因。采取减少进入凝汽器的低旁冷却蒸汽和提高低压轴封的供汽压力有力措施

解决了机组启动过程中的安全隐患

相当于缩短了机组的启动时间

取得很好的效果

为同类型机组的问题解决提供参考方向。

Abstract

There has been a problem of low temperature of low pressure cylinder seal in thestart-up process of two units in a factory. After analysis

the main reasons are the temperature drop of the steam supply and the poor drainage of the pipeline.By taking effective measures to reduce the LP bypass steam entering the condenser and increase the steam supply pressure of low pressure cylinder seal

the hidden safety hazards in the start-up process of the unit are solved

which is equivalent to shortening the start-up time of the unit and achieving good results

thus providing a reference direction for solving the problems of the same type of units.
