摘要 基于石蜡火灾灭火实验模型,采用标准管枪和灭火器两种灭火系统,测试了直流水、泡沫、水凝胶、干粉和二氧化碳等典型灭火剂对石蜡油盘火的灭火效果。采集分析了石蜡火灾扑救过程中的热辐射和温度变化数据,记录了不同灭火剂的灭火时间、灭火剂用量、降温效果、沸溢喷溅和复燃情况等。对比了不同灭火剂的灭火效能和优缺点,并针对不同灭火剂进行了灭火应用分析。该研究结果对丰富可熔化固体火灾燃烧理论、提高灭火技战术和人员防护水平具有重要意义。

Abstract:This study developed an experimental model for extinguishing paraffin wax fires. The model used a standard tube gun fire extinguisher and a standard fire extinguisher. The paraffin pan fire extinguishing experiment evaluated the extinguishing effects of typical extinguishing agents, including direct water flow, foam, hydrogels, dry powders, and carbon dioxide. The experiments yielded data for the thermal radiation and temperature changes during the paraffin fires. The extinguishing efficiency was then assessed from the data. The assessments included the extinguishing time, the needed amount of extinguishing agent, the cooling effect, the effect of radiation and the ability to prevent boil over, splashing and rekindling of the fire. This study then compared the fire extinguishing efficiencies, advantages and disadvantages of various extinguishing agents, and application methods for the various extinguishing agents. This study develops the theory of fusible solid fires and improves fire-fighting techniques and personnel protection capabilities.
