【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]:In the early stage of fire extinguishing by water mist, the flame intensification phenomenon of intense combustion will be observed in a short period of time. A number of experiments were designed to compare the flame enhancement of different fuels under different conditions. It was found that the droplet splashing caused by impinging the fuel on the fuel plate could increase the contact area between the fuel and the air and enhance the flame combustion. Water mist boiling in the fuel may also strengthen the flame, but the gain effect is not obvious, and the gasification rate of the fuel has a great influence on the flame enhancement.
