双室火灾烟气特性的实验研究

本文在１／２缩尺建筑模型中，取双室－走廊结构，以标准木垛为火源，对建筑火灾的初始阶段进行了实验模拟。着重研究了火灾初期的烟气特性及其变化，包括烟气温度及烟气中ＣＯ＿２气体和炭颗粒浓度。本文目的在于在探索和发展中等尺寸火灾实验模拟手段和方法的同时，定性地确定火源功率对烟气特性的影响，并积累一定的实验数据，为建筑火灾的分析和模化提供实验基础和依据。

An Experimental Investigation of Fire Smoke Properties in Double Room

An experimental simulation has been performed within the 1/2 reduced-scale building model to investigate the fire smoke properties during the initial stage of building fires.Wood cribs were used and smoke temperature,CO_2 and soot particle concentration were measured in the burning room,adjacent room and corridor. The purpose of this study is to provide a qualitative understanding of the effect of heat release rate on the smoke properties and accu mulate some experimental data for building fire analysis and modeling,meanwhile,to devel op the means of middle-scale fire test.
