4种杨梅植物的燃烧性及应用

为比较植物的燃烧性,用自行设计的燃烧试验装置对4种杨梅科植物和2种易燃的对比植物的鲜枝叶进行了燃烧试验,在测定和分析样品引燃时间、有焰燃烧阶段烟气温度变化和质量损失过程等的基础上,提出了植物的燃烧性参数P,即单位质量可燃物在有焰燃烧阶段产生的烟气净温升峰面积与引燃时间之比。根据P值对4种植物的燃烧性进行了由大到小的排序,即：矮杨梅Myrica nanaCheval、大树杨梅Myrica esculenta Buch.-Ham、荸荠杨梅Myrica rubravar. atropurpurea Tsen、东魁杨梅Myrica rubravar. typica Tsen。荸荠种和东魁具有果实经济价值高、枝叶燃烧性差的优点,可以用于生物防火,东魁燃烧性最差,与昆明地区的重要防火树种银荆相当,是营造经济树种型防火林带的首选树种。

Combustibility and Application of 4 Types of Bayberry Species

To compare combustibility differences of woody plants and provide theory basis for the correct developing biological fire-prevention,combustion experimentations of living branches and leaves of 4 types of bayberry species and 2 types contrastive combustible species were tested with an experimental equipment designed by the authors.The combustion characteristic parameters,namely the ratio between area of smoke temperature net rising curves apices per unit mass fuel in flaming stage and ignition time,were put...
