I've been playing around with a pile of bricks making a rocket type cook stove. Just a little pile of bricks on the ground. It works, but I'm getting much more smoke than I anticipated. and I have a concern about the amount of fuel that can be fed into this without having to clean it out. I put a cast iron pot of beans on and got it to boiling then let it die out. But the firebox is full of ash. If I had tried to cook those beans on a continuous fire, I would have had to clean it while it is in operation. Any different experiences? What to do? Grin and bare it?
How tall is it? I think you'll get less smoke if it's at least a couple feet tall and fairly airtight, with convection driving stronger airflow.
The amount of ash might be due to the variety of wood, and fuel with a lower proportion of minerals will perform better. Or if there's charcoal left, faster airflow will again mean more-complete combustion.

About 12 inches or so. Not airtight as this is just experimental. I agree, I built it a little higher by stacking the top layer on edge, and then I extended the fire chamber the length of a brick. I'll have to go try and salvage more brick. I'm burning bois d'arc, hackberry and honey locust. All are supposed to be good wood. I started pulling some of the ash out and used larger wood and allowed coals to build up. The coals cook as well as the fire.
