[Stoves] Charcoal as space filler in TLUD reactors

[Boll, Martin Dr.]

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.
