摘要
为研究钾、钠对生物质阴燃传播速度的影响
在松榆混合粉中添加不同比例（0~1.65%）的KCl、NaCl制成生物质棒、炭棒
对其阴燃传播速度进行对比分析。结果表明：KCl、NaCl均可提高生物质棒和炭棒的阴燃速度
生物质棒阴燃速度随KCl比例的增加而增大
最大为原生物质棒的1.5倍;NaCl影响更显著
在0.33%~1.65%范围内均为原速度的1.8倍;对于炭棒
KCl、NaCl对阴燃速度的提高均为先增后减
最大阴燃速度分别在0.99%、0.33%处获得。这些影响结果与氧转移理论一致
并符合Langmuir-Hinshelwood机理;NaCl比KCl影响更明显的原因是Na的相对原子质量更小且性质更活泼。
Abstract
To investigate the effects of potassium and sodium on the propagation velocity of biomass smoldering
biomass rods and char rods were made by adding different proportions （0-1.65%） of KCl and NaCl to a mixture of pine-elm powder
smoldering propagation velocity was compared and analyzed. The results show that both KCl and NaCl enhance the smoldering propagation velocity of biomass and char rods. The smoldering velocity of biomass rod increases with the proportion of KCl
reaching a maximum of 1.5 times that of the original biomass rod. The effect of NaCl is more significant
which is 1.8 times of the original velocity at 0.33%-1.65%. For char rods
the enhancement of smoldering velocity by KCl and NaCl both firstly increases and then decreases
and the maximum smoldering velocity is obtained at 0.99% and 0.33% proportions of KCl and NaCl
respectively. The effect results are consistent with the oxygen transfer theory and the Langmuir-Hinshelwood mechanism. The more significant influence of NaCl compared to KCl is attributed to sodium’s smaller relative atomic mass and more reactive properties.
