By a whole scale combustion experiment with wood pile of Pinus sylvestris var. Mongolica, we studied the characteristics of temperature field when wood pile burning, and analyzed the effects of sizes of wood pile and wind speed on variation in temperature field. It showed that the temperature in wood pile might reach as high as 900 ℃ when it was burning. Under the condition of equal distance from the facet studied to wood pile, the temperatures varied greatest in the facet perpendicular to the direction of wind flow. Larger size of wood pile and faster wind speed might accelerate the rate of combustion so that it made faster increment in environmental temperature. These results could provide information to fire fighting and rescue, and computer simulation of wood pile combustion.%通过对樟子松原木楞堆进行室外燃烧试验,研究楞堆燃烧时的温度场特性,分析原木楞堆体积和风速对环境温度场变化的影响.试验结果表明,在燃烧过程中,楞堆温度可达900℃;对于环境温度场来说,在所有研 究平面与楞堆距离相等的情况下,与风流动方向垂直的平面温度变化最大.较大的楞堆体积和较快的风速会加速楞堆的燃烧速度,从而使周围环境温度上升较快.研究结果为贮木场火灾消防援救和计算机模拟提供依据.
