摘要
燃气轮机的煤气入口处安装了型号为Laser Gas II的氧量仪,使用过程中因氧量仪误报和波动造成跳机的事件频频发生。本文研究发现其原因是:氧量仪的光学镜头和内部主板污染严重,造成内部温度升高产生报警和波动。本文通过增加吹扫系统和优化控制程序两种方法,彻底解决以上问题。大大提高了氧量仪的使用寿命,减少备件成本;杜绝非计划跳机,减少生产成本。
LaserGaslI Oxygen meter is installed at the inlet of the gas turbine, the gas turbine trip which is caused by the false positives and fluctuations of the oxygen meter. The paper found that the reason is： Oxygen meter optical lens and internal board pollution is serious, resulting in internal temperature rise alarm and fluctuations. In this paper, by increasing the purge system and optimize the control program two methods, completely solve the above problems. Greatly improving the oxygen meter life, reduce spare parts costs; put an end to non-planned trip, reduce production costs.
