| 摘 要： | 用渐近分析法对一维稳态逆流阴燃进行了分析，模型中将填充床沿气体流动方向分成三个区，预热区、氧化降解区和热解反应区，分析表明，阴燃峰值温度和阴燃传播速度主要由降解来决定，崦氧化降解和热解反应同时决定热解区的结构，推导了活性物全部转换情况下的温度分布，气固质量分布表达式

| Abstract: | A one dimensional model of steady reverse smolder in a packed bed is analyzed using asymptotic methods. The packed bed is divided into three parts along the direction of the air flow: the preheat zone,the exothermic oxidation zone and the endothermic pyrolysis region.The peak temperature and the velocity of smoldering propagation are determined mainly by exothermic oxidation. The oxidation and the pyrolysis determined the structure of the pyrolysis region simultaneously. For the case of complete conversing of active material , some expressions such as temperature , gas and solid mass distribution are obtained. |
