My plan is to determine the air flow pattern with no combustion first. 
Fuel stacked into a chamber shaped like a combustion chamber.  Then pack 
the stove with the same fuel, adjust to the same air flow and test 
emissions and WBT to see what happens. To do this during combustion (the 
better way) means we need to inject a surrogate standard into the inflow 
air.  If we can find a good gas to use as a surrogate standard during 
combustion we can do a  -lot- of things. Boggles the mind!
