| 摘 要： | 为了研究细水雾喷头在不同喷射压力情况下针对油盘火的灭火效果,采用正庚烷为火灾燃料,在4.6m×3.3m×4m(长×宽×高)的空间内,针对同一型号的细水雾喷头在不同喷射压力下进行了灭火实验,在实验过程中采用热电偶树和气体分析仪对火焰温度及火场氧浓度进行了测量,得到了不同喷射压力下细水雾灭火的影响规律,为细水雾灭火设计、检验标准制定及细水雾灭火产品的开发提供了相应的实验依据.

| Abstract: | In order to investigate the effect of water mist nozzle to extinguish heptane fire under different injection pressure, a series of experiments were performed in an enclosed compartment of 4.6m×3.3m×4m with a certain type of water mist nozzle under various injection pressure. Thermocouples tree and gas analyzer were used to measure the temperature and oxygen concentration in the flame. The effect of injection pressure on the affectivity of water mist suppressing pan fire was gained, which provides corresponding experimental foundation for designing water mist system, establishing test standard and developing new product of water mist. |
