Even if you have preheating of 300 C the maximum radiation heating with 13 mm of fire insulation that would be added is about 250 to 300 C to beams with their lower mass. That gives you 550 to 600 C, not the 800 to 850 C needed by the WAI report for their hypothesis.

In addition, there is a delta T in the radiation equation between the emitter and the absorber and if the starting temperature of the absorber is higher (due to preheating) the heat flux will be lower.

What about conductive heating do to soot black body radiation?

Of did you forget about that little phenomenon?

Mod Warning This thread appears to be morphing into the formal debate thread, plus some pictures are being repeated/repeated/repeated so I think it is best that I close this thread and encourage the conversation to continue in either the debate thread or another suitable thread.

Please do not re-re-repeat pictures; once is enough and then refer back to the post.

Please continue the discussion in whichever existing thread you feel is most appropriate.

But it's ok because they imply they are expertz at demolitionz too
