摘要
室内家具引起的火灾对人和财产的威胁非常大,本文重点研究单人沙发的燃烧特性,以及对室内火灾动力学参数的影响.实验是在符合ISO9705的标准单室(3.6m×2.4m×2.4m)内进行的,通过对两个相同的单人沙发进行全尺寸火灾实验模拟,测量沙发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火灾参数,分析比较它们之间的关系,为火灾安全性能化设计和计算机模拟提供实验依据.研究结果表明,沙发的热释放速率与质量损失速率之间存在非线性关系.
The room fires mainly caused by upholstered furniture threaten human life and property. This paper investigated the combustion behaviors of single-seat sofa and fire dynamic parameters in a compartment. The full scale fire tests were conducted in the standard single room accorded with ISO 9705, whose inner dimensions are 3.6 m×2.4 m×2.4 m. Fire parameters such as the heat release rate and mass loss rate of the burning sofa and temperature profiles of inner room, have been measured. The relationships among the fire parameters were also studied. The results show that there is a nonlinear relationship between the heat release rate and the mass loss rate of the sofa.
