火灾烟气特征的实验研究

The Experimental Study on the Fire Smoke

烟气是火灾过程的重要物理现象 .烟气中悬浮的烟气颗粒目、尺寸分布、团聚效应和烟气的湍流效应是火灾探测的重要影响因素 .本文分析了火灾烟气的特征 。

The smoke is the important physical phenomenon in fire process. Its many properties, such as amount and size distributed of smoke pellets, reuniting and turbulent effects, are important affecting factors to fire detection. This paper analysis the fire smoke properties and provides the experimental basis for more parametric characters of the smoke.
