摘要： 压缩空气泡沫灭火技术是目前解决超高层建筑火灾扑救难题的重要发展方向，但经垂直长距离输送后的压缩空气泡沫灭火性能仍待深入研究。本文拟采用超高层建筑实际配置的泡沫枪，通过调节输入参数，模拟产生与实际超高层工况一致的等效泡沫，并通过标准20A木垛火灭火试验，验证经垂直长距离输送的压缩空气泡沫扑灭A类火的能力。试验结果表明：混合液流量为92 L/min、气液比为9.8：1.0时，供泡141 s可完全扑灭明火，10 min内无复燃；混合液流量为126 L/min、气液比为6.0：1.0时，供泡54 s可完全扑灭明火，10 min内无复燃。

Abstract: Compressed air foam fire extinguishing technology is an important development direction to solve the fire fighting problem in super high-rise buildings, but the fire extinguishing performance of compressed air foam after vertical long-distance transport is still to be further studied. In this paper, the foam nozzle actually configured in the super high-rise buildings was used to simulate the equivalent foam with the same performance as the actual working condition by adjusting the input parameters. And the ability of compressed air foam after vertical long-distance transport to extinguish Class A fire was verified by the standard 20A wood crib fire extinguishing test. The results showed that the flame can be completely extinguished for 141 s when the mixed liquid is 92 L/min and the gas-liquid ratio of the foam is 9.8：1.0, and there was no reignition within 10 min. Meanwhile, the flame can be completely extinguished for 54 s when the mixed liquid is 126 L/min and the gas?liquid ratio of the foam is 6.0:1.0, and there was no reignition within 10 min.
