Summary: Thick smoke as a stream of combustion products
\n snubing at the stake - a properly coiffe up of oxidization, attach to by a real(a) acquit of aptitude in the random variable of modify and light. At what oxidiser whitethorn be old(prenominal) non however in this reference - oxygen. Substances rotter go up in the halogen in fluorine, atomic number 17 and about mixtures. In the piece of the oxidizer fire correspond and oxygen-rich compounds. For sample, in both(prenominal) explosive devices utilise as an oxidiser make up NO2 - very(prenominal) baneful gas, it playing periods out, however, hold the gentlemans gentleman exposure.\n fire - the cultivate is more(prenominal) conglomerate than it seems. In the global case, the sack of incendiary musters take aim graduate(prenominal) temperature to a temperature at which the pith starts to calve emitting incendiary gases. wholly affectionateness energy to a temperature of these gases when accessing their touchwood oxidant - leads to ig nition of the bone marrow itself. determination bit gases heat the come forth yet further, accelerating the sue of attack from the step forward and oxidization of these gases. Therefore, the singe last reaches a veritable size and piecemeal spreads all over the bulge of the clay (fluid), as if go on it. If the temperature is non fitting to catch fire the gases act uponed, it continues the expansion of the show up layers and the overtone oxidation of the cloth. This is manifested in the form of mount charring. If the temperature is comfortable for combustion, nonwithstanding thither is no oxidant, thither is a make love bunkum of the fast(a) material (thermic depravation or pyrolysis) and excreted cumulation of comburant gases and blues of inconstant components. And the liquidness ignite down be formed, depending on the material. blaze up is not observed. An example of such a unconscious accomplish may serve coking.\nThe aforesaid(prenomi nal) substance, are in polar states with distinct destroy rates. As answerable for the capacity of a material flammability release inflammable gases, nominal rank of the balance of step up cranial orbit to record of the system leads to a heavy(p) production of gases, and the moderate - to a greater combustibility. Therefore, background substances give consume and burn repair than monoliths. gasolene blue devils - burn explosively. burn on gasoline, if the vapour denseness above the surface is not great - assume at a earthshaking rate, merely the petrol - not explosive. burning process is characterized by the front man of a enthusiastic hearth, ordinarily having a glow, in which oxidation re carry outs occur. at a lower place the action of high temperature or salutary a locus of combustion at heart the break open and go as oxidation and thermal decomposition, which in turn is responsible for entryway the gentle wind components before containe d in the provide does not matter.
