I'd like to make biochar, I'd also like to use the heat to warm my home.
I've heard that a retort might be the way to go? (I understand this to mean a metal container bolted to the side of my woodburner with some smallish air holes between the burner and 'retort' container?)
I'm mindful of CO poisoning and wanting to keep combustion gasses out of my lungs. Are there some designs I should look for? Or am I going to have to design my own?
I guess if I already had a burner with a large burn chamber a tin would probably do fine.
I'm interested in using some rocket principles and getting the combustion as efficient as possible (for the heat generation) so I guess I'm wondering if anyone has done an indoor rocket stove that produces charcoal?
It may be a case of getting the welder out and some scrap and trying a few things.
