气体灭火系统在LNG码头的设计应用

Application of Gas Fire Extinguishing System in Design of LNG Jetty

根据国内现行规范要求,提出防护区个数多,各防护区面积小的LNG码头控制室等建筑物的气体灭火系统选用预制无管网七氟丙烷全淹没灭火系统。阐述七氟丙烷的灭火机理、灭火系统设置、灭火系统控制方式及灭火装置的组成,对灭火系统的主要技术参数进行计算。

According to the requirements of the current domestic codes, it is put forward that the pre- fabricated no-network heptafIuoropropane fire extinguis- hing system should be selected in the design of gas fire extinguishing system for control room and other build- ings in LNG jetty with multiple and small protection zones. The fire extinguishing mechanism, settings, con- trol mode and composition of the heptafluoropropane fire extinguishing system are elaborated, and the main technical parameters are calculated.
