Sarbagya: Can you narrow down the type of stoves you are looking at? And why?
You seem to be talking of TLUDs, and when mentioning consuming char is that in a TLUD? We have seen some nice designs with secondary being preheated with a central pipe, not the exterior gap you describe. At least one stove developer (Kirk Harris) has argued for using that exterior space for added insulation. A topic fairly easy to compare in the lab you appear to have available.
