Abstract


Fixed fire extinguishing systems , flammable liquid fire hazard used three gas fire extinguishing system , foam fire extinguishing systems , conventional water spray fire extinguishing system . Three systems sustainable , there is a hazard to the environment , personnel, equipment , may cause a boil over other shortcomings , the water mist good for a Class B fire extinguishing effect but it has a broad application prospects . In order to further improve the efficiency of water mist fire suppression , water mist , composite additives, interaction studies carried out containing the composite water mist kerosene pool fire . Firstly, by theoretical calculation derived suited to extinguish the kerosene pool fire droplet critical size of 80 to 250 M , according to this critical droplet size can be critical fog flow . Second , in the critical droplet size of water mist and fog flow orthogonal design theory , under the same experimental conditions, screening and compound additive combinations apply to kerosene pool fire experiments show that our composite additives to improve water mist extinguishing kerosene pool the efficiency of the fire . Last through comparative experiments containing the composite water mist and pure water mist and kerosene pool fire interaction , draw with composite water mist extinguish the mechanism of kerosene pool fire : capture the scene by the cooling effect of the flame and composite additives free radicals in fire suppression , to control the fire as a small fire , reduced air entrainment into the small fire , into the fire of oxygen concentration reduced accordingly , then a stifling effect as the main extinguishing mechanism .
