摘　　要：为了模拟实际燃烧状况,在实验风管内底板上平铺一层聚积物,在不同的回风速度、不同的风管尺寸以及不同的聚集物厚度的条件下,利用热电偶测量火灾时风管内的温度场。通过实际风管内火灾实验数据,得出了模型中各测点的最高温度,并分析风管的截面尺寸、聚集物的分布、风速的大小对于火蔓延以及各测点最高温度的影响。To simulate the actual combustion, puts a flat of sediment on the soleplate in the air duct and measures the temperature field in the air duct, by thermocouples when the fire happens in the condition of different air velocities, different air duct sizes and different distribution of the sediment. Through analyzing the field measurement of the fire experiment, obtains the highest temperature reading of each thermocouple, and analyses the influences of cross section size of the air duct. distribution of the sediment and the air velocity on the fire propagation and the highest temperature of each thermocouple readinge.
