森林可燃物燃烧时火焰的温度,无论是对于林火的发展,或是对于火生态效应的研究,都是必须考虑的一个参数。例如,火焰的温度高,热量释放过大,形成高能量的对流柱,甚至产生火旋风或火爆。又如,火焰的温度高,不仅使林木损毁程度加大,还会使土壤中有机质破坏加剧,植物营养元素损失也加剧。影响森林可燃物燃烧时火焰温度的因素有:可燃物化学组成、物理状态(颗粒大小、堆积紧密程度等)以及燃烧条件……。在实际的森林火烧中,火焰的温度是千
The temperature of the flames when combustibles are burned is a parameter that must be taken into account, either for the development of forest fires or for the study of fire ecological effects. For example, the flame temperature is high, heat release is too large, the formation of high-energy convection column, or even fire whirlwind or hot. In another example, the high temperature of the flame not only increases the degree of forest damage, but also aggravates the destruction of organic matter in the soil and aggravates the loss of plant nutrient elements. Factors influencing the flame temperature when burning combustible materials include combustible chemical composition, physical state (particle size, packing density, etc.) and combustion conditions. In the actual forest fire, the flame temperature is 1000
