RR机组消防系统的安全性分析

Analysis on the Safety Performance of Fire Fighting System for RR Compressor Unit

西气东输干线RR压缩机组消防系统探头误报警,会导致机组故障停机,且造成CO2喷射的浪费。通过RR与GE机组消防系统的对比,以及对安全仪表多重化技术的介绍,根据探测器的误报概率以及运行的实际需要,进行逻辑优化。优化后的系统减少了因探测器误报警而导致的机组紧急停车系统(ESD)停机,并将经济损失和对平稳输气的影响降至最小。

The false alarms from the probes in fire fighting system of RR compressor unit in West-East Natural Gas Pipeline may cause the compressor shutdown in malfunction and waste CO2 spraying.Through comparing the fire fighting systems of RR and GE units,and introducing multi-redundancy technology for safety instruments,the logic is optimized based on the rate of false alarms and practical requirement of operation.The optimized system reduces the ESD downtime,and thus the economical loss and the influence on smoothly gas transmission are minimized.
