If we want to thoroughly prevent the occurrence of fire accidents in shopping malls, we must start with elimi- nating fire hazards. Through the experiment, small size and narrow space fire combustion cha- racteristics 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 rea- sonable suggestions according to the characteristics of different stages of combustion.
