最近,美国纽约等地的消防专家正在试验借助风扇对付高楼火灾。他们不指望能把火扇灭,而是希望能减少高楼火灾中“喷灯效应”的发生概率,进而减少人员伤亡。在高楼火灾中,消防员经常遇到门微敞时,玻璃遇热炸裂使风突然而入的情形。风火瞬间结合很可能在毫无征兆的情况下产生火球

Recently, fire experts in places like New York in the United States are experimenting with fans to deal with tall buildings. Instead of hoping to extinguish the fire, they hoped to reduce the probability of “blowtorch” effects in high-rise fires and thereby reduce casualties. In high-rise fires, firefighters often encounter when the door is slightly open, the glass suddenly burst into the case of hot burst. An instant combination of wind and fire is likely to produce a fireball without warning
