Particle size droplets of water mist fire-fighting capability and the relationship

A water mist extinguishing function is more complex, it is with the type of fuel, fuel quantity and the combustion speed and mist particle size and so on. Particle size droplets and mist extinguishing the relationship between the ability is quite complex, the general said,water power sprayer Ⅰ and Ⅱ mist liquid oil tanks used to fight the fire better, and do not stir the oil tanks liquid level.

2, under normal circumstances, it is difficult class Ⅰ Class A combustible mist off because class Ⅰ mist can not penetrate carbonized layer soaked burning material. However, if the spray rate is high, the surface combustion, or the closure has a greater degree of reduction in the case of oxygen, A class of fire was put out can Ⅰ type mist. This phenomenon shows that drop size distribution can not be determined only by water mist fire exterminate a given capacity. Can the fire was extinguished, depending on characteristics such as fuel, confined space effect, mist intensity and mist velocity (momentum) and other factors.

3, for a given protected object, the size of the droplet mist ability and suitability determination is not the sole basis, it also has a relationship with the flame garden sprayer backpack spray direction, mist intensity and speed of the jet
