昆明地区主要造林树种鲜枝叶的燃烧性研究

Comparative Study on Combustibility of Living Branches and Leaves of Major Planting Species in Kunming Area

为比较造林树种的燃烧性,为开展生物防火提供理论依据,采用自行设计的燃烧试验装置对昆明地区12种主要造林树种的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温升峰面积与引燃时间之比。结果表明,12种造林树种的燃烧性由强到弱的排序为:圆柏、柳杉、直杆蓝桉、云南樟、墨西哥柏、冲天柏、华山松、黑荆、云南油杉、云南松、旱冬瓜、银荆。

To compare combustibility differences of planting species and to provide theoritical basis for the correct development of biological fire-prevention,combustion experimentations of living branches and leaves of 12 major planting species in Kunming area were tested by self-developed experimental setting.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 forward based on lighting tim...
