Abstract: In order to explore the flame burning characteristics of wood with different textures,5 kinds of wood were selected. The experimental device was set up. A total of 15 groups of experiments were designed in this experiment. From the aspects of mass loss rate, maximum flame height and combustion duration, the combustion characteristics of transverse, vertical and oblique textured wood were analyzed. The results showed that the mass loss rate of wood was related to texture. Texture had the least influence on the maximum flame height when pine was burning, and the greatest influence on Chinese fir. Furthermore, the burning duration of beech was longer than that of other four kinds of wood. Besides, the burning duration of Chinese fir was relatively short. The research results were helpful to better grasp the influence of texture on the flame characteristics of wood combustion. It provided theoretical support for material selection and fire prevention of wooden structure buildings.
