Type of the 2nd combustion and its characteristic (go up)
1, the condition that forms by combustion and the characteristic that produce the moment, combustion can be divided for And .
2, combustible is character when the action that does not have exterior fire cause, because of Or And the combustion that place of accumulation of heat produces, call blaze.
3, spontaneous combustion is material is in namely ignite without the outside below source condition, what as a result of its itself interior produces , Or Change and produce quantity of heat and accumulate, make temperature rises ceaselessly and natural flaming phenomenon.
4, It is the lowermost temperature that points to combustible happening spontaneous combustion.
5, citing of chemical spontaneous combustion: , dynamite suffers bump and explode, , because coal piles up exorbitant and spontaneous combustion.
6, It is to show material is transformed quickly by a kind of condition another kind of condition, be in the instant with the form releases tremendous energy, or it is gas, vapour is in instantaneous happening is acuteness expand wait for a phenomenon.
7, combustion content can be divided by configuration for Burn, Burn and Burn.
8, differ according to gas and oxygen can be being lighted to mix a state before combustion, its combustion means can be divided for Burn and Burn.
9, Combustion can light sexual gas and vapour element and aeriform oxidant to diffuse each other, the edge mixes Bian Ran to burn.
10, the characteristic of diffusion combustion is: Combustion is compared , blaze temperature is relatively inferior, diffuse blaze does not move, the mixture that can light aeriform oxidant is in can light aeriform spout to undertake, combustion process does not happen Phenomenon (blaze shrinks the phenomenon of igneous aperture interior) .
11, Combustion is to point to can light gas, vapour to be the same as air beforehand (or oxygen) mix, encounter ignite the blaze that source generation contains wallop.
12, Flaming characteristic is: Combustion reaction is sharp, temperature is high, blaze transmission rate is rapid, reaction gas mixture does not diffuse, cause of a fire introduces to produce center of a blaze namely in can burn gas mixture, become quantity of heat and source of concentration of chemical and active particle.
13, premixed gases gives hair raw power to burn from nozzle gush, be like velocity of flow Combustion speed, form stable combustion blaze in the canal, combustion is sufficient, combustion rate is rapid, combustion area shows high temperature white-hot shape, be like the combustion of gas lamp; If can light gas mixture to be in nozzle velocity of flow Combustion speed, can happen " temper " .
