Dear Paul >"Biggest problem I see with many attempts to make TLUD-style barrel-size charcoal makers is the poor quality of the lid or top to allow in secondary air that goes to the concentrator hole." I thought Alex English had a good solution worked out for that long ago. Alex, can you please post a picture of your maize kernel TLUD gasifier with vertical pipe and central secondary air inlet with vanes? That could be attached to anything that makes gas below it. As the basic purpose it flaring and creating draft, it should do fine. It would keep the main heat away from the barrel top. Regards Crispin in meilie-land
