240系列气体燃料发动机的安保系统设计

Design of security system for a 240 series gas fuel engine

以天然气为燃料的气体燃料发动机,在安保系统设计上需要考虑外部环境、人员安全和发动机自身的运行安全要求。为达到安全目的,240系列气体燃料发动机在安保系统中设计了双层天然气供给管路、负压通风、氮气吹扫、互锁阀组、天然气泄漏检测、涡轮后吹扫、进排气防爆、曲轴箱防爆、发动机爆震/失火检测等主动和被动安全设置。

The gas fuel engine with natural gas as fuel needs to take into account the external environment,personnel safety and the operation safety requirements of the engine in the design of the security system.In order to achieve the safety purpose,active and passive safety devices such as double-wall natural gas supply pipeline,negative pressure ventilation,nitrogen purge,interlock valve group,natural gas leakage detection,turbine postpurge,intake and exhaust explosion-proof,crankcase explosion-proof and engine knock and fire detection have been designed in the the security system for a 240 series gas fuel engine.
