摘要
贮木场火灾被公认为最难扑救的火灾之一,它是森林火灾中较常见且危险性较大的一种事故。本文重点研究贮木场楞堆燃烧的特性。实验是在符合ISO9705的标准单室(3.6m×2.4m×2.4m)内进行的,通过对两个相同材质的楞堆进行火灾实验模拟,测得楞堆燃烧过程中的热释放速率、质量损失速率以及室内温度场等参数。分析实验结果,为制定防火规范和计算机模拟提供实验依据。研究结果表明,贮木场楞堆燃烧温度场和热释放速率呈一直线平稳燃烧态势。
It is very difiqcuh to put out the fire in log yard, which is conmmon and regarded as one of the most dangerous accidents in forest conflagrations. The paper is mostly focused on the combustion characteristics of stacking wood in log yard. The experiment is implemented in a standard room with specification 3.6 m × 2.4 m × 2.4 m which accords with the criteria ISO9705. By the experimental simulation on the two stacking woods with the same quality, the parameters such as heat release rate, quality loss rate and indoor temperature in the combustion process of stacking woods are tested. The results show that the burning temperature filed of stacking wood in log yard is positively relevant to the heat release rate, which will provide basis for enacting fire prevention regulation and computer simulation.
