以工业酒精为燃料，在一房间与走廊相联的模型中，研究了封闭燃烧一定时间后，突然进风对室内火灾的影响。分别在走廊进风。起火室进风等情况下，观察了燃烧状况的变化，测量了典型截面的温度分布，并对一些现象出现的原因作了分析。指出这种突然进风，可在短时间、一定范围内降低温度，但主要效果是促进燃烧。当室内有明火源时还会引发烟气回燃，致使其中的温度急剧升高。
Using industrial alcohol as fuel, in a model associated with a corridor in a room, the effect of sudden air intake on indoor fire after a certain period of closed combustion was studied. Enter the wind in the corridor. In the case of entering the wind in the firing chamber, the changes in the combustion conditions were observed, the temperature distribution of the typical section was measured, and the causes of some phenomena were analyzed. It is pointed out that this sudden air intake can reduce the temperature in a short time and within a certain range, but the main effect is to promote combustion. When there is an open flame in the room, it will cause the smoke to rekindle, causing the temperature to rise sharply.
