为综合比较植物的易燃性,用自行设计的试验装置对元江栲(Castanopsis orthacan-tha)等14种昆明地区主要常绿木本植物的活枝叶进行了9次燃烧试验。在测定和分析样品含水率、引燃时间、有焰燃烧时间、试验过程中烟气温度和质量变化等基础上,提出了易燃性参数,即单位质量可燃物在有焰燃烧阶段相对于无样品对照试验的烟气净积温与引燃时间之比。根据该参数计算了14种植物9次燃烧试验的易燃性参数,并对树种进行了易燃性综合排序,即炮仗花杜鹃>元江栲>光叶石栎>云南含笑>滇青冈>云南野山茶>小白花杜鹃>矮杨梅>米饭花>云南樟>厚皮香>大白花杜鹃>岗柃>野八角,分析了造成不同种植物活枝叶易燃性差异的原因。
In order to comprehensively compare the flammability of plants, 9 burning experiments were conducted on live branches and leaves of 14 evergreen woody plants in 14 Kunming areas such as Castanopsis orthacan-tha using a self-designed test set. On the basis of measuring and analyzing the moisture content, ignition time, flame burning time, flue gas temperature and quality during the experiment, the flammability parameters were proposed, that is, Sample control test flue gas net product temperature and ignition time ratio. According to the parameters, the flammability parameters of nine kinds of plants in nine combustion tests were calculated, and the flammability parameters of the species were calculated, that is, the cucumbers of Rhododendron fortunei> Yuanjiang River> Quercus glaucae> Yunnan smile> Cyclobalanopsis glauca Tea> Small White Flower Rhododendron> Shorty Yangmei> Rice Flower> Zhangzhuang> Thick Leathery> Rhododendron rhododendron> Gang 柃> Wild Star anise, analyzed the causes of the flammability difference of living branches and leaves of different species.
