火灾烟流污染巷道断面的烟流温度测试

测试了火源点下风侧巷道断面上的烟流温度分布，以及火灾过程中断面烟流温度变化，研究结果表明：下风侧巷道断面烟流温度分布是不均匀的，靠近巷道顶板烟流温度较高，靠近底板和壁面较低；当断面烟流平均温度或最高温度相同，随距火源点距离的增加，断面上各测点间烟流温度之差增大。

Test of Fume Temperature at Roadway in the Section Polluted by Fire Fume

The fume temperature distribution below the fire area in the section of the roadway, and the changes of the fume temperature in each sectiom are studied.The achievements show that fume temperature distribution is not even in section,it is higher near the roof of drift, and is lower at the foot and the side walls;as the distance to the fire area increases, the difference of fume temperatures of various measuring points in the section increases, when the average or the highest temperature is the same.
