细水雾透过网格形障碍物熄灭油池火的试验

Experiment on Fine Water Spray to Extinguish Fire on Baffle Plate with Grid-shaped Obstacle

为了研究障碍物对细水雾灭火的影响,在网格形障碍物阻隔条件下,利用细水雾对小尺寸油池火的灭火效果进行了试验研究。在3.0 m×3.0 m×2.8 m的标准受限空间内,选取火灾功率固定的较小尺寸煤油池火进行一系列细水雾模拟灭火试验。试验结果表明:障碍物之间的距离、障碍物与火源间的距离等都对细水雾抑制火焰有明显影响。在较小尺寸油池火存在的情况下,适当增加网格形障碍物与火源间的距离,并减少网格形障碍物的等效面积至10%以下,可以使细水雾有效抑制、熄灭油池火焰。

In order to study the influence of the obstacles to the fire extinguishing with fine water spray, an experimental study on the fire extinguishing results of a small size oil pond fire with fine water sprays under the isolation conditions of the grid shape baffle plates of the obstacle. In a standard limited space of 3.0 m × 3.0 m × 2. 8 m, a small size kerosene pond fire with a fire disaster fixed power was selected to conduct a series of fire extinguishing experiments with fine water sprays. The experimental results showed that the distance between the obstacles, the distance between the obstacle and firing source and the others could have an obvious influence for the fine water sprays to control the flame. When the fire existing in the small oil pond, the distance between the grid obstacle and the fire source increased and the equivalent area of the grid obstacle reduced to 10% below could make the fine water spray effectively control and extinguish the fire on the oil pond.
