轰燃是指建筑内部火灾的突发性全面燃烧现象,即当室内火灾燃烧形成的可燃气体充满室内整个空间且达到一定浓度时,与空气形成爆燃性混合气体,发生爆炸性燃烧,从而导致整个空间内其他房间没接触大火的可燃物也一起被点燃而燃烧,这种现象称为轰燃。1实验过程实验在一个由10 mm钢板围成无防火措施的房间内进行。房间两侧装有感温探头(实时监测房内温度),房
Burn-off refers to the burst of comprehensive internal combustion fire phenomenon, that is, when the combustion of indoor fire combustion gas filled the room full of space and reach a certain concentration, the formation of deflagration with air mixture, the explosive combustion, resulting in the entire space The other combustible materials in the other rooms that are not exposed to the fire are also ignited and burned together, a phenomenon known as flashover. 1 Experimental process The experiment was carried out in a room surrounded by 10 mm steel plates without fire protection. Room equipped with a temperature probe on both sides (real-time monitoring of room temperature), room
