well some misunderstandings.. but making heat riser in ceramic fiber bord as long as posible with large bell and then larger channels than normal underground to some place outside (whitout chimney) up through ground somewhere the wind never creates backdraft could maybe make enough draft"push" fore a small batchbox. i think working from start, and logically as i see less less draft as bell get warmer but start is most critical anyway

By the way: another effect of that port is a lot of turbulence behind it in the riser, needed for mixing of burnable wood gas and fresh (preferably preheated) air. Rounding off the edges of the port has the effect of a smoother air flow and inadequate mixing so I recommend against it. Been there, done that, tried and tested, measured and rejected. what about separating the fluids splashing them together by placing a brick where the port is and have an opening on each side of that brick making turbulens in middel of flame, well i tryed but cant really messure
i think the "port" i was thinking of smoothing/curving the eghes was the one from bell to bench/chimney

so chimney draft is more safe and stable than riser draft.. unless you Cant make a to big fire
sekondary air help regulate fires size
so much can be done wrong

also its posible to bring fresh air from outside in at the bottom of closet aound barrel. fresh warm air.. possibly creating some overpressure in room if too sealt.. have not tryed..

drive.google.com/file/d/1Eu4Yww2Od4G6c8sD5lJyfxw6BBmtZUqX/view?usp=sharingi would rather have it was only doors but bigger and higher whit space fore oven on top and whitout the lit the air is cirkulating up around barrel an down in right wall when closed note its a small barrel, room is 12 m3 very small batchbox like system. might make burning champer bigger.. insulatet metal chimney, but outside.. had to learn the startup.
