所谓燃烧热,即1摩尔的可燃物完全燃烧时释放出的热量。还有一个相近的名词:热值或发热量,指单位质量的可燃物完全燃烧时释放出的热量。这两个名词是有区别的,但目前常混用。燃烧热在林火管理中是一个极为重要的参数。为了定量地预测林火行为,常常用各种林火蔓延模型,美国国家火险等级系统中广泛应用的林火蔓延模型——罗森美尔(Rothermel,R.C.)模型,在该模型中林火蔓延速度用反应强度(即火头中单位面积上发出的热量)来表示,而后者与可燃物
The so-called heat of combustion, that is, 1 mole of combustible material is completely released when the heat of combustion. There is a similar term: calorific value or calorific value, refers to the unit of mass of combustible material is completely released when the heat. The two terms are different, but they are often used nowadays. Burning heat is an extremely important parameter in forest fire management. In order to quantitatively predict forest fire behavior, it is common to use various forest fire spread models, the widely used model of forest fire spread in the National Fire Rating System, the Rothermel (RC) model, in which forest fire spreads The speed is expressed in terms of reaction intensity (ie, the amount of heat emitted per unit area of the fire head), which is compared with combustibles
