摘要
为比较旱冬瓜Alnus nepalensis不同直径活枝的燃烧性差异,在森林防火紧要期内,分7个径级对活枝进行了燃烧试验。在测定样品直径、含水率、引燃时间、有焰燃烧熄灭时间、试验过程中烟气温度和质量损失变化过程等基础上,提出并计算了能够表征活枝燃烧性能的综合燃烧特性参数P。根据该参数,直径为1.11 cm、0.90 cm、0.71cm、0.56 cm、0.46 cm、0.34 cm活枝的综合燃烧性是直径为1.31 cm活枝的2.06、5.49、11.86、50.39、121.74、282.99倍。
To compare combustion performance differerce of different size live branches of Alnus nepalensis,combustion experiments of 7 diameter class’s live branches were conducted during the prohibitive period of forest fire.A general combustion parameter P which can well indicate the combustion characteristics was proposed in this paper based on determining diameter,moisture content,igniting time,going out time of flaming combustion,smoke temperature and weight losing of sample during experimental period.The general combustion parameters were accounted of 7 diameter class’s branches,and the parameters P of diameters equaled to 1.11 cm,0.90 cm,0.71 cm,0.56 cm,0.46 cm,0.34 cm were 1.72,5.49,11.86,50.39,121.74,282.99 times respectively as large as the P of diameter equaled to 1.31 cm.
