粒径对森林腐殖质阴燃传播的影响
|
摘要
设计阴燃炉,采用帽儿山实验林场内的红松林腐殖质作为实验材料,研究不同粒径对腐殖质阴燃温度变化趋势、峰值温度、阴燃传播速率以及失重过程的影响。结果表明,不同粒径腐殖质的阴燃温度变化趋势相似;峰值温度会随着粒径的减小而升高;粒径对腐殖质阴燃的传播速度和质量变化影响均不明显;阴燃传播速度会随着燃烧深度的增加而减慢。
A smoldering furnace was designed. Taking Korean Pine forest humus in Mao'ershan Experimental Forest Farm as experimental materials, the influence of humus particle size on smoldering temperature change trend, peak temperature, spreading speed of smoldering and weightlessness was studied. The results showed that, smoldering temperature change trend of different particle size humus is similar; the peak temperature will increase with the decrease of particle size of humus;effect of particle size on spreading velocity and quality change in the process of humus smoldering are not significant;the spreading velocity slows down with the increase of combustion depth.
