And I probably should have been more explicit about what I meant by 
'directly'.  Any temperature where you are getting complete combustion, 
is extracting the maximum amount of heat energy from the chemical energy 
of the cellulose in the wood.

This was in response to the idea that some woods burn hotter than others.

What temperature works best in _your_ wood stove is another matter. 
Also some temperatures burn stuff other than cellulose.

Thank You Kindly,
