Abstract Water mist is one of the important substitutes of halon fire extinguishing agents with the advantages of clean and environmental protection. However, there will be a short time of flame intensification in the fire extinguishing progress of water mist, which threatening the safety of surrounding combustibles and fire fighters. The main objective of this study is to assess the suppression performance of N2 twin-fluid water mist containing KQ compound additive (composed of 6% fluorine surfactant and K2CO3) on ethanol pool fire, and analyze the suppressing mechanism on the flame intensification phenomenon. Experimental results showed that: the fire extinguishing time of several fire extinguishing agents from low to high was N2 twin-fluid water mist containing KQ compound additive

含KQ复合添加剂的N2双流体细水雾抑制乙醇火灾的火焰增强效果评价

摘要 细水雾具有清洁、环保等优点，是哈龙灭火剂的重要替代品之一。但细水雾灭火过程中会出现短时间的火焰激化，威胁周围可燃物和消防人员的安全。本研究的主要目的是评估含KQ复合添加剂（6%氟表面活性剂和K2CO3组成）的N2双流体细水雾对乙醇池火灾的抑制性能，并分析对火焰增强现象的抑制机理。实验结果表明：几种灭火剂的灭火时间由低到高为含KQ复合添加剂的N2双流体细水雾
