[Stoves] Lowering emissions

[Tami Bond]

Paul,

There probably is a reference but I'm not aware of it. It's just my 
observation from watching wood burn. Some volatile matter always escapes 
from the end. If the piece is short it all escapes from the end. If the 
piece is longer and the cross-grain pressure is high or cracks develop, 
volatile matter escapes from the middle. This is one reason that I think 
fireplace burning is so different from cookstove burning. There's a big 
difference in the heat transfer (in) and mass transfer (out).

The model that Mark Bryden put together for his dissertation research 
might help to address this question.

cheers,
Tami
