Different fuels do release different amounts of heat when burned, this is true. But, the amount of heat in a fuel, and "temperature" are two different things. Did you not understand my explanation of how that worked?

Memory can get foggy after even a few years, much less 20. Brains are not as pure as we like to think. This is why witness testimony is such weak evidence in a courtroom, where physical evidence like fingerprints are considered much better. People's memories suck.

edit: So how about this one. If wood fires "burn at a low temperature", how does the inside of a forest fire get over 1000 C? If wood just burns at a set temp, wouldn't that be the temp they can reach?
