| 摘 要： | 通过实验研究了不同类型喷头对灭木垛火的影响。实验采用了ZSTX和ZSTP两种类型喷头,在不同的水压力下灭木垛火,通过实验现场观测和测得的烟气温度,烟气组分变化来分析对比灭火的效果和对烟气的影响。通过对比分析实验数据,可知ZSTX喷头在0.2MPa的水压力下可以实现灭火,ZSTP喷头在0.4MPa才可以实现灭火。喷淋实现灭火时产生的CO比只能实现控火产生的CO少。

| Abstract: | This paper presents an experimental study on two types of nozzles （ZSTX and ZSTP） for fire fighting, in different working pressures. The effects on smoke and fire fighting were analyzed by measuring the smoke temperature and gas composi- tion. The results show that the ZSTX nozzle can extinguish the experimental fire in 0. 2MPa, while the ZSTP nozzle can extin- guish the fire in 0. 4MPa. The CO products for the sprinkler which can extinguish the {ire are less than those for the sprinkler which can control the fire. |
