Abstract

The gradual phase-out of hydrofluorocarbons (HFCs) and other fluorinated compounds from automatic suppression systems and extinguishing foams is increasing the need for an alternative fire suppression method that can match their performance. Water mist, when combined with additives, can serve as a viable alternative. An exhaustive review of the literature highlighted that solvents, and especially alcohols, form a new and intriguing class of additives for the water mist. In the present study, the first seven primary linear alcohols have been tested as water mist additives in various concentrations ranging from 0.6 % to 20.0 %. Results showed that most alcohols, methanol excepted, induced lower extinguishing times than pure water. A detailed statistical analysis of the extinguishing times revealed that pentanol and butanol significantly outperform other primary linear alcohols, with superior cooling and the fuel and flame region contributing to their superior performance. Linear regression of the extinguishing times related to the alcohol’s characteristics provided insights into the mechanisms behind the better cooling of pentanol and butanol additives.

增强水雾灭火作用的酒精添加剂

自动灭火系统和灭火泡沫中的氢氟碳化物和其他含氟化合物的逐步淘汰，增加了对能够与其性能相匹配的替代灭火方法的需求。当与添加剂结合使用时，水雾可以作为可行的替代方案。详尽的文献回顾强调，溶剂，尤其是醇，形成了一个新的和有趣的一类添加剂的水雾。在本研究中，以不同浓度（0.6% - 20.0%）的水雾添加剂测试了前7种初级线性醇。结果表明，除甲醇外，大多数醇的灭火时间都比纯水短。对灭火时间的详细统计分析表明，戊醇和丁醇的性能明显优于其他原线性醇，因为它们具有优越的冷却性能和燃料和火焰区域，从而具有优越的性能。对与酒精特性相关的灭火时间进行线性回归，可以深入了解戊醇和丁醇添加剂冷却效果更好的机理。
