摘要
杯式燃烧器试验是消防领域用于测定气体灭火剂最小灭火浓度的经典方法。自哈龙灭火剂被淘汰以来,哈龙替代物经历了不同相态的发展,促使杯式燃烧器测试系统进行相应的改进,同时基于杯式燃烧器测试系统的灭火性能评价研究也在不断拓展。综述了国内外杯式燃烧器测试系统的使用和改进研究,重点介绍了适用于气相、液相、固相和复合相灭火剂的杯式燃烧器测试系统和测试方法,分别对气相、液相、含添加剂细水雾、干粉、复合灭火剂的灭火效率进行了总结和分析,综述了各相态灭火剂灭火性能评价研究。未来,杯式燃烧器测试系统仍将不断被改善,在灭火剂筛选和灭火性能评价等方面将发挥更重要的作用。
Cup burner test is a classical method for determining the minimum extinguishing concentration of gas extinguishing agents in the fire protection field.Since the halon extinguishing agent is eliminated,halon substitutes have undergone the development of different phase states,which has promoted the corresponding improvement of the cup burner test system.At the same time,the research on fire extinguishing performance evaluation based on the cup burner test system has been expanding.This paper reviews the use and improvement research of the cup burner test system at home and abroad,focusing on the cup burner test system and test methods applicable to gas-phase,liquid-phase,solid-phase,and compound-phase extinguishing agents.It is found that liquid-phase extinguishing agents and solid-phase extinguishing agents can be made into steam,fine droplets,or suspended powder by an auxiliary device to participate in cup burner experiments.Moreover,the emergence of composite fire extinguishing agents promotes the development of a two-phase input cup burner test experimental system.This paper also reviews the evaluation of fire extinguishing performance based on cup burners.It is found that the extinguishing efficiency of gas-phase extinguishing agents is related to their heat capacity.Also,liquid-phase extinguishing agents such as perfluoroketones participate in the cup burner test in the form of vapor,which consumes flame-active radicals by decomposing the resulting radicals.Further,the fire-extinguishing effect of fine water mist containing additives is determined by the competitive relationship between the chemical action of additives and the evaporation capacity of pure water.In addition,the fire-extinguishing efficiency of solid phase extinguishing agents is related to the particle size.For synergistic fire extinguishing research,an inert gas/chemical fire extinguishing medium composite extinguishing agent has a positive synergistic effect,which is affected by the premixed ratio.In the future,the cup burner test system will continue to be improved and will play a more important role in fire extinguishing agent screening and fire extinguishing performance evaluation.
