对比故障前后的数据

找出发生故障的原因为疏水器故障、省煤器发送罐圆顶阀故障和凝汽器补水阀内漏。通过更换缺陷设备

制定相应的防范措施

解决了闭式水积气的问题

保障了机组的安全运行。

Abstract

Due to the pressure drop of the manifold when the closed cooling water of a 600 MW power plant steam turbine during normal operation. This paper analyze the results of on-site inspections and compare data before and after failure

then it find out the cause of the failure is the steam trap failure

the economizer sending tank dome valve fault and the condenser water filling valve inner leakage. By replacing the defective equipment and formulating corresponding preventive measures

the problem of closed-type water accumulation gas is solved

and the safe operation of the unit is guaranteed.
