| 摘 要： | 细水雾灭火初期,在短时间内会观察到剧烈燃烧的火焰强化现象。设计了多组实验对比不同燃料在不同工况下的火焰强化现象,发现液滴通过撞击油盘燃料引起的液滴飞溅可以增大燃料与空气的接触面积,强化火焰燃烧。细水雾在燃料内发生扬沸也可能强化火焰,但增益效果不明显,同时燃料气化率对于火焰强化程度有很大关系。

| Abstract: | The oil pool flame would be enhanced suddenly and burn violently at the beginningof extinguishing pool fire using mist water.Experimental study was conducted to compare the fire enhancement phenomena using different fuels under different burning conditions.It was found that droplets spattering caused by mist water impacting fuel can increase the contact area between fuel and air.Water mist boilover can also cause fire enhancement,but the effect is small.Meanwhile,the fuel gasification has a great influence on the fire enhancement. |
