氮气灭火系统对受限空间木垛火的窒息特性研究
Asphyxiation characteristics of nitrogen fire-extinguish-ing system in wood stack fires of confined space
摘要
Abstract
Nitrogen fire-extinguishing system has great development space in building fire protection field due to its environmental protection,energy saving,high stability.In order to broaden the application field of nitrogen fire extinguishing system,the effects of nitrogen extinguishing system on fire ex-tinguishing parameters including extinguishing time,oxygen concentration and flame temperature of wood stack fires in confined space are analyzed through a small-scale experimental model.The results show that nitrogen fire-extinguishing system has a good asphyxiation and fire extinguishing ef-fect on the wood stack fires in confined space,and the fire extinguishing time of the wood stack fires with different fire loads is closed in the confined space..关键词
