| 中文摘要: |
| 用锥型量热计研究了三种烟叶 (安徽烤烟、河南烤烟和四川烤烟 )在暴露于不同辐射热通量 ( 1 0 k W2 /m2 、2 0 k W/m2 和 30 k W/m2 )下的燃烧特性。实验结果表明 ,在较低的辐射热通量下 ,烟叶的燃烧过程主要是以阴燃为主 ;在较高的热通量下 ,烟叶先发生着火燃烧 ,再转为阴燃。 |
| 英文摘要: |
| The combustion characteristics of three kinds of tobacco leaf have been studied using the Cone Calorimeter at three heat fluxes,i.e.10kW/m\+2,20kW/m\+2and 30kW/m\+2.The results show that at lower heat fluxes the combustion of tobacco is characterized as smouldering. At higher heat flues e.g. more than 20kW/m\+2,the tobacco become ignited first, then flame extinguishes itself a few seconds later (after ignition) and the combustion is converted into smouldering. |
