燃烧的种类大致可分为下列五种 (1)稳定燃烧和不稳定燃烧 普通燃烧,随着物质燃烧的加剧,温度不断上升,散热速度加快,当燃烧产生的热和散失的热相等,温度不再变化。我们把这种燃烧就称为稳定燃烧。 有的物质燃烧,如爆炸,一旦发生着火,产生热量的速度远远地超过散热速度,温度急剧升高。我们把这种燃烧叫做不稳定燃烧。这种燃烧可在瞬间达到高温,使然烧产物急速气化,发生急剧的热膨胀,对周 The types of combustion can be broadly divided into the following five types: (1) Stable combustion and unstable combustion Common combustion. As the combustion of materials increases, the temperature rises and the cooling rate increases. When the heat generated by combustion is equal to the heat lost, the temperature does not rise Change again. We call this burning stable combustion. Some substances, such as explosions, explode. Once a fire occurs, the rate of heat generation far exceeds the rate of heat dissipation and the temperature rises sharply. We call this burning unstable combustion. This combustion can reach high temperatures in an instant, so that the rapid combustion gasification products, the rapid thermal expansion, the week
