View Full Version : Burning Temperature of Jet Fuel
subject
Does anyone know? I can't find any decent info on the web without having to read through 9/11 conspiracy theories.
May I ask what is wrong with 9/11 conspiracy theories.
If you can discredit any of the theories I'd be interested to hear.
Sorry I can't answer your question.
There is a wide range of possible temperatures depending on a lot of variables like gas density, mixture, flows, etc. The exhaust temperatures of the jets that I used to fly ranged from some 400 in min power to 1080C The afterburner flame can melt most metals.
When you're googling include a -911 in the keywords. That will remove from the search all web pages mentioning 911.
Most people don't know this but jet fuel is nothing but a grade of Kerosene:

who said there's anything wrong with 9/11 conspiracy theories...or who said that it was my intention to prove or disprove them ? All I'm saying is that while trying to find info on the burning temperature of Jet Fuel, all I can really find is 9/11 conspiracy theories...that's not a good or a bad thing...but, it is indeed the way it is. The "-911" bit seems to be working a bit better, thanks.
cooljayman 02-01-05, 11:31 AM Strange question. But I think anywhere from 600C to 1000C. There are many other variables involved. Please be more specific.

I don't think it is a question of "ignition temperature." I am no chemist, but think that the "burning" can generated heat but as temperature rises, the reverse reaction (or some other endothermic reactions) will soak up energy.
Thus in a well insulated box, with fuel and oxidizing agent continuously present, one should go to a temperature where the forward burning raction is releasing heat at the same rate the the reverse endothermic reactions are soaking it up. This equal rate temperature (for the pressure conditions, concentrations etc.) is what determines the temperature achieved, not the ignition temperature. It seems possible, to me, that some fuels with low ignition temperatures could have higher "equal forward and reverse rate" tempertures than fuels with higher ignition temperature, but then again, I am not a chemist.

Not to jack the thread, but the problem with 9/11 conspiracy theories is the same as the problem with all conspiracy theories. The lack of evidence is always considered proof of how widespread the conspiracy is. To ask someone to disprove them is a logical fallacy.
Shifting the burden of proof: demanding that the person denying and assertion prove his/her case, whereas the burden of proof is upon the person who argues the position.

Now, back to your regularly scheduled program.

Ah, you're right, I misread his question. Good catch. I'm no chemist either but temperature of combustion is not an absolute - it depends upon extraneous variables such as atmospheric composition and pressure.
I think I know what he's referring to now, and that is whether or not a petroleum fire would have been hot enough to erode the integrity of structural steel in the WTC towers. Lol.
Odin'Izm 02-07-05, 01:26 PM Jet A is aviation kerosene, it is very similar to the common kerosene used in home lamps and heaters. It is a clear liquid that is a mixture of different kinds of fuel molecules, hydrocarbons, made up of hydrogen and carbon. Kerosene is similar to gasoline and diesel fuel in that it is a mixture of hydrocarbons of different sizes. The sizes of the molecules are measured in terms of the number of carbon and hydrogen atoms in the each molecule. Jet A liquid contains molecules with between 4 and 20 carbon atoms.
Ignition temperature is relatively low for avrage jet fuel (in atmospheric pressure) 300C
Burning temperature With plenty of oxygen is 3500F, or 1900C.
