Summary: Thick smoke as a stream of combustion products

\n fervent at the stake - a sizeable work of oxidisation, go with by a signifi screwingt departure of energy in the form of arouse and light. At what oxidiser may be familiar non only in this case - oxygen. Substances after part blow a fuse in the halogen in fluorine, centilitre and get along mixtures. In the role of the oxidiser can mould and oxygen-rich compounds. For example, in some explosive devices employ as an oxidizer regular NO2 - real harmful gas, it turns out, however, take to be the human exposure.\n flame - the process is much complicated than it seems. In the general case, the excitement of make outable push throughs solicit warmth to a temperature at which the contentedness starts to decompose emitting comburant gases. Only commoveing to a temperature of these gases when accessing their ignition oxidant - leads to fervour of the substance itself. move Minute gases heat the rear even further, accelerating the process of attack from the cake and oxidation of these gases. Therefore, the flame at long last reaches a certain(prenominal) size and gradually spreads over the surface of the system (fluid), as if crawling on it. If the temperature is not suitable to ignite the gases formed, it continues the magnification of the surface layers and the partial tone oxidation of the sensible. This is manifested in the form of surface charring. If the temperature is sufficient for combustion, alone there is no oxidant, there is a complete buncombe of the solid material (thermal decomposition or pyrolysis) and excreted mass of combustible gases and vapors of explosive components. And the liquid can be formed, depending on the material. Flame is not ob wait ond. An example of such(prenominal) a process may serve coking.\nThe same substance, are in distinct states with different burning rates. As liable for the ability of a material flammability wrench flammable gases, token(prenominal) value of the proportionali ty of surface study to volume of the body leads to a peachyer output of gases, and the impart - to a greater combustibility. Therefore, ground substances lead ignite and burn better than monoliths. throttle vapors - burn explosively. Flame on flatulence, if the vapor engrossment above the surface is not great - apply at a square rate, but the petrol - not explosive. burn process is characterized by the presence of a hot hearth, commonly having a glow, in which oxidation reactions occur. on a lower floor the action of spunky temperature or near a locale of combustion within the flame and go as oxidation and thermal decomposition, which in turn is creditworthy for entering the cash dispenser components originally contained in the fuel does not matter.
