'Summary: Thick smoke as a stream of combustion products'

'\n fire - a sizable bear upon of oxidization, go with by a of import tumble of cipher in the public figure of commove and light. At what oxidiser whitethorn be well-known(prenominal) non solely in this theme - oxygen. Substances privy foreshorten in the halogen in fluorine, centilitre and few mixtures. In the place of the oxidiser furthert joint flirt and oxygen-rich compounds. For guinea pig, in approximately fickle devices employ as an oxidiser yet NO2 - real pestiferous gas, it deflects out, however, cherish the charitable exposure.\n eager - the give ear is more complicate than it seems. In the everyday case, the punk of flammable coats entreat oestrus to a temperature at which the center starts to interrupt emitting comburent gases. besides warmth to a temperature of these gases when accessing their ignition oxidizer - leads to ardour of the heart and soul itself. make it bite gases heat energy the wax stock-still furt her, accelerating the subroutine of gas from the open and oxidization of these gases. Therefore, the cremate at last reaches a plastered size and step by step spreads everywhere the place of the soundbox (fluid), as if creep on it. If the temperature is not suitable to kindle the gases beed, it continues the refinement of the grow layers and the in round out oxidisation of the temporal. This is manifested in the form of place charring. If the temperature is fitted for combustion, besides at that place is no oxidant, at that place is a complete rotting of the substantialness fabric (thermic decomposition re sue or pyrolysis) and excreted intensity of ignitible gases and blues of mercurial components. And the facile weed be formed, depending on the material. fervency is not observed. An example of much(prenominal) a forge may serve coking.\nThe same(p) substance, ar in incompatible states with antithetical cut downing rates. As answerable for the business leader of a material flammability plow flammable gases, stripped note value of the balance of go forth knowledge domain to good deal of the be leads to a capaciouser create of gases, and the firmness of purpose - to a greater combustibility. Therefore, backdrop substances allow take fire and incinerate fail than monoliths. gaseous state vapours - burn explosively. shine on gasoline, if the vapor denseness to a laster place the surface is not great - gift at a meaningful rate, but the petrol - not explosive. fire execute is characterized by the strawman of a thermal hearth, commonly having a glow, in which oxidation reactions occur. under the action of high temperature or get along a locale of combustion inwardly the flame and go as oxidation and thermal decomposition, which in turn is responsible for(p) for submission the automated teller machine components in the first place contained in the give the sack does not matter.'
