"Yes fire does burn paper at a much lower temperature than is required to melt steel.
But, steel can still melt under conditions that will not allow paper to burn."
"Why don't you just answer the question? Currently your claim makes you look ridiculous, maybe you can make us all look ridiculous by answering the point.
How could there have been steel melting temperatures that didnt burnt the paper.
Go on, make us look stupid. We're waiting. In the picture you gave before severely charred wood supports steel beams that have sagged. You claim temperatures were involved that were MUCH MUCH greater than what would cause sagging steel, yet at the same time you require much less temperature to not cause paper to ignite. A massive contradiction in your conspiracy theory?... no surprise there then, just add it to the huge pile of others."
I am staying on topic
Edx.
Earlier, I presented a hypothesis for melting steel in deep hotspots within the WTC debris pile.
The answer to your question was clearly provided there and in other responses.
Molten steel does not mean burning steel.
Molten steel only requires exposure to the correct amount of sustained ambient heat.
The combustion of paper, burning, requires the presence of the correct amount of sustained ambient heat
plus sufficient oxygen.
In a hermetically sealed hot pocket, at some point pieces of the paper, could have become uncovered from under a cover of insulating dust but after the ambient oxygen had been consumed.
But, I am not suggesting that the paper cannot be broken down. Depending on the circumstances behind its heat exposure, the paper can eventually suffer pyrolysis. It could char, it could decompose into gases, even possibly release some oxygen from its organic composition and allow some minor partial combustion.
Referring to the WTC debris specimen that Bart Voorsanger investigated, it is quite possible that the areas of apparently protruding paper were once covered by a heavy layer of mostly non-organic, concrete or gypsum dust which provided protection, initially from combustion, and later from pyrolysis.
Certainly it would not be too surprising to expect that those "meteorites" once had some dust coverage which debris removal workers had no reason to keep in place. There is little evidence of any remaining dust in the specimen photos.
But there is evidence of significant paper charring in the images
Grizzly Bear provided.
Continually falling red chip-laden dust would still ignite at 430+ C temperatures and release heat.
If more heat is generated than dissipates in the pocket, then the ambient temperature will continue to rise.
Unless the process is broken, at some point in time, the melting temperature of steel will be reached, but unless sufficient ambient oxygen becomes available, the paper will not be able to combust.
