The combustion ratio of oxygen to kerosene (by mass) is 2.56 (and this is fuel-rich to increase performance). Air is 20% oxygen, so that would mean you would need about 13 pounds of air to burn a pound of jet fuel. Air has a density of about 2.7 pounds per cubic meter (larger than a cubic yard), so that would mean about 4.8 cubic meters or ~5 cubic yards of air. Plenty of air available. Entire houses and forests have no problem burning to cinders. Even entire cities. What you think is a problem, isn't. Otherwise, where did all the jet fuel go?
The fire behavior following the aircraft impacts is described in NIST NCSTAR 1-5A. In general, there was little sustained fire near the area where the aircraft hit the towers. Immediately upon impact of the aircraft, large fireballs from the atomized jet fuel consumed all the local oxygen. (This in itself would have made those locations rapidly unlivable.) The fireballs receded quickly and were followed by fires that grew inside the tower where there was a combination of combustible material, air, and an ignition source. Little combustible material remained near the aircraft entry gashes, since the aircraft "bulldozed" much of it toward the interior of the building. Also, some of the contents fell through the breaks in the floor to the stories below.
The actual blast furnaces burn coke, so you have to have an air supply to provide the oxidizer. This all takes place in a tightly confined area, so you don't have a natural draft to help sustain the heat release. It took nearly an hour for the Twin Towers fires to heat the columns to their failure point. It is a matter of how fast you are burning the fuel.
It was just hanging around in a pool slowly heating up the area then. It also blew the lobby windows out with a fireball after coursing down the shafts.

I don't think you know what you are talking about. NIST said the fireballs made oxygen scarce and the impact zone barely burned.

Interesting to know.
It's called a blast furnace for a reason.

I really don't know what you are talking about.
