狭长受限空间火场传播速率的影响因素研究

Long and narrow space limited by the impact of the fire spread rate factors

基于对狭长受限空间火场的实验研究,并综合了煤矿井下巷道的特点,研究了影响狭长受限空间火场传播速率的多种因素。研究结果表明:空间内的障碍物会增加火场的传播速率;固体壁面会产生反射波,对火场的传播速率有抑制作用,甚至可能造成熄火;狭长空间的长度是能否形成爆轰(火场传播达到最大速率)的条件之一。

Based on the long and narrow space is limited experimental study of the fire, Studied the effects of long and narrow space limited the fire spread rate of a variety of factorso The results show that：Space obstacles will increase the spread of the fire rate;Solid wall will be reflected wave,Rate of spread of the fire inhibit, May even cause engine; Long and narrow space is whether the length of one of the conditions for the formation of detonation（ Maximum rate of spread of the fire）.
