Abstract

Experimental research findings are reported on the characteristics of physicochemical processes at different stages of fire development and suppression. Fires involving solid materials like wood, cardboard and linoleum were investigated. The minimum necessary and sufficient volumes of firefighting liquid (water with different additives, e.g., a foaming agent, bentonite, bischofite, etc.) and their spraying times were identified. Differences in spraying characteristics (droplet velocities, sizes and concentration) were recorded. A relationship between the spraying characteristics of fire extinguishing agents and efficiency of fire suppression was established. Correlations were identified between the operational characteristics of fire detectors during fire suppression involving several fire extinguishing agents. The most efficient compositions in terms of fire suppression time and extinguishing agent consumption were found for typical indoor combustible materials. Mathematical equations were derived to predict the key characteristics of fire suppression.

使用专用液体成分遏制和扑灭车厢火灾

实验研究结果报告了火灾发展和灭火不同阶段的物理化学过程特点。研究了涉及木材、纸板和油毡等固体材料的火灾。确定了灭火液体（水与不同的添加剂，如发泡剂、膨润土、双沸石等）的最小必要量和足够量及其喷射时间。记录了喷射特性（液滴速度、大小和浓度）的差异。确定了灭火剂喷射特性与灭火效率之间的关系。在使用几种灭火剂灭火期间，确定了火灾探测器工作特性之间的相关性。针对典型的室内可燃材料，找到了灭火时间和灭火剂消耗量方面最有效的成分。得出了预测灭火关键特性的数学公式。

期刊介绍： Fire Safety Journal is the leading publication dealing with all aspects of fire safety engineering. Its scope is purposefully wide, as it is deemed important to encourage papers from all sources within this multidisciplinary subject, thus providing a forum for its further development as a distinct engineering discipline. This is an essential step towards gaining a status equal to that enjoyed by the other engineering disciplines.
