火气系统和火灾报警在西气东输二线中的应用

Application of Fire and Gas System and Fire Alarm in Second West to East Gas Pipeline Project

西气东输二线整条线路设有压气站、分输站、联络站等多种类型站场,共计82座,设计压力为12 MPa。为了保证站场人员及设备的安全,根据相关规范在站内重要场所设置了火气系统,即可燃气体检测及报警、火焰检测及报警、火灾检测及报警系统。介绍了火气系统的设置及功能实现,以及火焰探测器、可燃气体探测器、感温探测器、感烟探测器及报警系统的设计选型。

There are 82 stations in Second West to East Gas Pipeline including compressor stations, distribution stations, communication stations, and so on. According to relevant codes, fire and gas system is set up at important place of the station, which can perform combustible gas detection and alarm, flame detection and alarm and fire detection and alarm. The establishment and operation of fire and gas system are described and the design type selections of flame detector, combustible gas detector, temperature sensor, smoke sensor and alarm system are described.
