| 摘 要： | 在搭建的小型阴燃实验台上,对木屑的一维水平逆向阴燃过程进行实验研究,获得了稳定的逆向阴燃过程,并对各种因素对阴燃过程的影响进行了试验.结果表明,随着空气流速的增加,阴燃的传播速度随之增加,而材料含水量的增大会降低阴燃的传播速度.另外对阴燃过程中产生的CO2和CO进行分析,计算出这两种气体在不同空气流速下的平均排放速率.

| Abstract: | A pilot scale experimental apparatus is established to simulate horizontal oriented smolder. A series of experiments with sawdust smolder in an opposed forced air flow is performed. The results show that opposed smolder process can propagate steadily.Both oxygen supply rate and water content of sample will influence smolder process. Propagation rate increases with the rise of air supply rate and it decreases with the growth of water content of sample.In addition,production of CO,CO_2 in smoldering have been analyzed and the average emission rate of gas in different air velocity are calculated. |
