商场火灾蔓延特性实验研究

The Characteristics of Fire Spread and Prevention and Control Measures in the Building of the Mall

摘要: 商场火灾事故一直是社会关注的焦点问题之一，要想彻底地预防商场火灾事故的发生，就必须从消除火灾隐患方面着手。通过小尺寸实验对狭长空间火灾燃烧特性进行研究，研究商场火灾从起火到旺盛期的发展变化过程及距离起火点不同位置火焰温度的变化和烟气的蔓延特性，并对不同阶段可燃物的热释放速率进行了分析。最后得出结论根据不同阶段的燃烧特点为制定商场火灾防控对策提出合理的建议。

Abstract: The fire accident in shopping mall has always been one of the focuses of the society. If we want to thoroughly prevent the occurrence of fire accidents in shopping malls, we must start with eliminating fire hazards. Through the experiment, small size and narrow space fire combustion characteristics were studied. This paper studies the development and change process of the market fire from fire to the vigorous stage, and the variation of the flame temperature and the spread characteristics of the flue gas at different locations at the fire point, and analyzes the heat release rate of the combustible materials at different stages. Finally, the conclusion is made to make reasonable suggestions according to the characteristics of different stages of combustion.
