The Fires in the WTC Wreckage Were Not Conventional Fires

Here is the definition of conventional fire smoke:

The smoke released by any type of fire (forest, brush, crop, structure, tires, or waste) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains particulate matter (PM or soot). Dark smoke implies the presence of soot. Soot is produced when a fire is oxygen starved, or has just been extinguished. Soot also has a high thermal capacity and may act to rob a fire of heat by carrying it away.

Here is a photograph showing conventional fires in the twin towers on 9/11:

Here is a photograph showing the area of the World Trade Center on 9/16/2001:

Here are the temperatures of the fires burning in the WTC wreckage on that day:

Conventional fires burning under tons of rubble would be oxygen starved, therefore the smoke produced would be black, not white. Also, large amounts of soot would have been produced in five days, therefore the temperatures of the oxygen starved fires should have been significantly lower.

The fires in the WTC wreckage were not conventional fires.
