摘要:

为研究火灾初期自动喷水灭火系统作用时对铺地材料燃烧性能的影响,利用火焰传播量热仪,以混纺地毯为例,分别研究了干态、含水率50%、全浸泡3 种状态下水对其燃烧性能的影响。试验结果表明:随着含水率的升高,混纺地毯的引燃时间增长,含水率高的混纺地毯不易被引燃;含水条件下峰值热释放速率比干态条件下大,火灾规模较大,火焰燃烧持续时间内总热值较小;含水条件下,总烟气生成量及组成成分峰值出现时间后移。

关键词: 燃烧性能, 热释放特性, 烟气生成量, 干湿状态, 混纺地毯

Abstract:

In order to study the effect of automatic sprinkler system on the combustion performance of floor covering materials in the early stage of fire, this paper used Fire Propagation Apparatus (FPA) to study the effect of water on the combustion performance of blended carpet in dry state, 50% moisture content state and full immersion state. The results showed that with the increase of moisture content, the ignition time of blended carpet increased, and the blended carpet with high moisture content was not easy to be ignited; The peak heat release rate in the water- containing condition was larger than that in the dry condition, the fire scale was larger, the total heat release in the flame combustion duration was smaller; Under the condition of water content, the peak value of the total smoke production and its components appears later.

Key words: combustion performance, heat release characteristics, smoke generation, dry and wet state, blended carpet
