采用大流量泡沫炮扑救大型储罐全面积火灾的探讨

简要分析了大型储罐全面积火灾着火面积大、热辐射强、易复燃、破坏力强等特点,指出了这类火灾的主要扑救难点是远距离作战、消防物资消耗大、战术要求高等。从泡沫液最低流量、泡沫液喷射方式和泡沫液选型3方面提出了用于扑救大型储罐全面积火灾的大流量泡沫炮的要求,指出泡沫炮的最小流量应不低于20000L/min,利用蛋白泡沫液采用集中喷射方式进行灭火。

Bubble Gun with Large Flow Rate Fighting Full Scale Fire of Large Tank

Fires of large storage tank feature larger scale, strong thermal radiation, easy recrudescence, enormous damage. The difficulties of fighting such fires are the long-distance operations, great fire fighting material consumption, high tactical require- ments. The guidelines for fighting full scale fires of large tank were presented in regard of minimum flow rate, foam concentrate and foam injection method. The minimum flow that should not less than 20 000 L / min. Concentrated injection and using protein foam were recommended.
