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.
Strange question. But I think anywhere from 600C to 1000C. There are many other variables involved. Please be more specific.
What grade of fuel? Each one has a different ignition temperature.
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.Stokes Pennwalt said:
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.Billy T said:
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.
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.

The statement that "jet exhaust will melt most metals" is extremely deceptive.
1.An open air hydrocarbon fire will not get over 1200 F,1800 F with forced oxygen.
2.Metals have an extremely wide range of melting points;sodium ignites spontaneously in air,mercury is liquid at room temp.,melting at -38 F,Aluminum will melt on your stove or in a wood fire,potassium melts at 146 F,magnesium will burn under water,lead will soften in the sun,osmium melts at 5477 F,and iron melts at 2795 F with construction steel melting at 2750 F.
The best reference material for physical constants such as melting points,boiling points etc.,is the CRC Handbook of Chemistry and Physics.
Facts are stubborn things,and until the Ministry of Truth burns all the old science reference books,it is very hard for the propagandists to spin their tales of deceit and fool the educated.

Holy shit, that is the most useful thing I read today!

It took me two and a half seconds to find the answer on google, jet fuel for common airliners is jet A-1 (as posted by odin). It's flash point is 38 °C and it's auto-ignition is higer than 220 °C. You guys can find the info at www(dot)shell(dot)com (why do I need 20 posts to post links?)
...not quite right.
Dear roscogre,
“Andre” never claimed, "jet exhaust will melt most metals".
What was said was, "The AFTERBURNER FLAME can melt most metals."
As those “reheat” combustion temp.s can range from 1500-ish at initial ignition (a slight dip from the relatively-stable turbine exhaust temp as the first fuel “dumps” into the stream) to well over 2500F at full-bore, this statement is entirely correct.
The erroneous notion that anything more than the aircraft impacts and subsequent fires were needed to bring down the Twin Towers is not…
A massive “conspiracy” surrounding 9/11 did, indeed, exist, but it did NOT involve explosives, thermite, thermate, or any of the other “obvious demolition techniques” bandied-about by various lay people and fringe-element websites.
NONE OF THE ABOVE WAS REQUIRED!
Many of the sixty-plus elevator shafts above the halfway point of the structure made excellent twenty-foot-wide blowtorches, once 24,000 gallons of jet fuel was poured down them and ignited…
All it really took was decades of deliberate agitation of psychotic religious fanatics worldwide by our last three equally-psychotic Republican administrations, and for those self-styled “leaders” to turn a blind(ed) eye to known threats at crucial moments.
Although they didn’t know the exact form it would take, and certainly weren’t prepared for the sheer scope of the event, various “black-op.s” groups within the CIA, NSA, FBI and the whole alphabet-soup of our so-called “intelligence community” had been striving diligently (at the behest of and with the full blessing of those same Republican lunatics) for some such “watershed” attack since the day the Berlin Wall came down, in order to preserve their precious d@mn&d BUDGETS from the inevitable result of the “ramping-down” of the cold war. Since any reduction in said budgets was, in their paranoid, delusional “judgment”, “…a threat to national security!” (read: “…a threat to our job security!”), they felt they had to do whatever it took to create a nice, solid, permanent, implacable “enemy” at whom we could be brainwashed into throwing billions of tax dollars for decades into the foreseeable future.
This they achieved famously, if on a somewhat larger and more heinous scale than they anticipated.
Never mind that their money and employment were never in any REAL danger (China, Israel, Korea, Pakistan, etc. etc., etc., would always have kept them busy enough) - they HAD to have their way, and they most assuredly have done so…
Add-in the profit potential of a second, unnecessary Gulf War for the “Bush-Laden Oil’glomerate”, Haliburton, Blackwater and dozens of other “defense” contractors and filthy-rich (emphasis on “FILTHY”) Bush family campaign contributors, and you have the exact formula for “What Really Happened”, to commandeer the name of one of the loonier “See that puff of smoke? Obviously it was blown up with bombs!” websites.

That's something conspiracy nuts forget, that elevator shafts can channel flames, which of course, is why you shouldn't try and use on in a fire.
Channelling fire increases it's potency incredibly. Once a friend and I were clearing out his shed, and throwing unwanted items on a bonfire. He had some louvre doors , three, linked by hinges, about three feet tall, so we arranged them around the rather tame bonfire, to corral it in. The louvres channelled air into the bonfire, and gave it an exit like a jet at the top, so the flames that had just been a couple of feet tall, were now about five feet tall, and the paint on the louvres flashed over, got sucked into the mix, and briefly, while that burned off, we had flames about seven feet tall.
Nice. A lot of ad hoc declarative false statements with nothing to back them up.
Anyone who can watch those videos and think it is anything other than a demolition is a fool or a liar.
No steel framed building has EVER suffered total collapse,much less cut and melted steel and turned concrete into dust,from fire,despite much longer,much hotter fires that engulfed the entire building.
There was a bigger fire in the same building.
Tons of thermite in the dust,and microspheres of iron which are formed when high explosive blasts molten steel.
All the tell tale signs of controlled demolition were apparent that day,including firemen counting down the building 7 demolition,BBC and CNN reporting it's collapse BEFORE it happened(whoops)and the owner admitting he decided to demolish it.:splat:
The fire was smoldering,almost out and people were standing in the hole made by the "plane" proving temperatures were extremely low.
But CENTCOM is admittedly paying thousands of low level intelligence officers to propagandize the public.
Thanks for helping to destroy our country.
