远离火源位置点烟气浓度变化规律的实验研究

EXPERIMENTAL RESEARCH ON THE SMOKE CONCENTRATION VARIATION AT THE LOCATION REMOTE FROM THE FIRE ORIGIN

建筑火灾致死的主要原因是烟气,且伤亡人员主要在远离火源位置处。本文在小尺度实验装置上进行了大量的实验,系统研究了燃料充分燃烧变化时的规律、烟气浓度在通道远点的变化以及两者的相互关系,推导了远距离处烟气浓度变化的关系式。

Smoke takes the leading role of lethality of the people in fires, most of the fatalities are in the locations remote from the fire origin. A series of experiments carried out in a reduced scale device to investigate the gases concentration variation rule at the remote location, especially related to the mass loss rate, Furthermore, the formula describing the smoke concentration variation is presented in this paper.
