可燃物是发生火的三大要素之一。可燃物所含的能量是通过光合作用过程积累起来的,燃烧时,这些储存的能量就被迅速地、有时甚至是爆炸性地释放出来。可燃物的能量大小与可燃物载量有直接关系,载量越大,潜在的能量也就越大;反之,潜在的能量也就越小。除了与载量直接相关以外,可燃物的能量多少还与可燃物的其它性质有关,这些性质不仅影响热量和热的形式,而且影响热的释放速度。可燃物性质包括(1)热值,由可燃物的化学组成所决定的,即萜烯、天然脂、不可燃矿物质(如硅等)的含量;(2)含水率;(3)个体大小或表面积与体积之比。
Combustible is one of the three major elements of a fire. The energy contained in flammable materials is accumulated through the photosynthetic process, and the stored energy is released quickly and sometimes even explosively. The size of the combustible material is directly related to the amount of combustible material. The larger the loading capacity, the greater the potential energy. On the contrary, the potential energy is smaller. In addition to being directly related to loading, the amount of energy in combustibles is also related to other properties of combustibles, which not only affect the forms of heat and heat, but also the rate of heat release. The combustible properties include (1) the heating value, which is determined by the chemical composition of the combustibles, ie, the content of terpenes, natural fats, incombustible minerals (such as silicon); (2) moisture content; Or the ratio of surface area to volume.
