TLUD-ers turn it as you want; Charcoal as space-filler means __somehow__ that "mixed fuel" is used in a TLUD. From that aspect it is a "hybrid-fuelled" TLUD. Change the ratio of the "hybrid-fuelled" TLUD to: wood-pieces as space-filler (by charcoal-packing). Run this different mixture and look. Who did this already? Interesting to hear about. - It would be as well interesting to know the difference in performance between test-runs with natural draft and with forced air.
Even by that different ratio, the burn can be stopped after outgassing, to get as final result charcoal. - Hybrid-fuelled TLUDs would get probably a better quality of resulting charcoal ( Frank, mentioned that as important difference for bio-char) P.S. We could stop guessing about the amount of more or less _primary air_ (caused by the minimal pressure of a fan or natural draft in different-dense TLUD-packages), and make an exact air-dosage by a rotameter, or less expansive and simpler by an aquarium-air-pump.
