Typical Faults and Prevention of GE 9FA Gas Turbine Power Plant Gas Purge System

本文介绍了GE 9FA清吹系统典型热工故障类型,分析其故障原因并制定相关防范措施。通过大量的实施实例,介绍了近年来某电厂采取的设备改进、逻辑优化等技术改造工作,为防范清吹系统故障提供多种思路。采取技术改进措施后,极大提高燃机清吹系统稳定性,有利于机组安全稳定运行。

This paper introduces the typical thermal fault types of the GE 9FA purging system, analyses the fault reason and formulate relevant preventive measures. Through the implementation of a large number of examples, the paper also introduces the recent technical innovation about the equipment improvement and logic optimization at any power plant, which provides a variety of ideas for preventing the fault of blowing system. After taking these measures, the stability of the combustion engine purging system is greatly improved, this is good for the safe and stable operation of the unit.
