Dear Ronald from Cold Farms >it appears to me that there is primary and secondary air entering through a most open bottom ring around the fuel container ...
There is, but reducing the airflow at that point is probably not optimal. The best is a slightly large channel then a constriction right at the point of entry into the fire. This gives the least flow resistance during preheating (and more time to get hot) and gives the greatest impetus to the incoming / injecting air. Its tiny mass has to carry it to the centre of the open space inside to get good mixing.
