Afterburning Rocket Stove Concept

- Just a simple idea that may make a rocket stove even more efficient at using all its fuel. Technically it should be really efficient as it is, but this modification (in theory) takes it up one more level.
Not much to it though. Just adding an updraft tube to make sure the gasses in the flue area get an extra bit of fresh air, and a conical shaped metal grid or mesh to diffuse and mix hot gasses and fresh air which should help burn any combustible residual stuff remaining.
I came up with a very similar concept. I call it a re-breathing rocket stove. Just about to test it out today. It was completed a month ago but have been waiting for nice weather
First off, batch box rocket stove makers do add secondary air already, which is not much different than this. The potential problem with this is what seems like the height of the "injection"..... The secondary air must be low enough to contact flame. If it's too high up, you are just adding an air conditioner to something you are trying to heat. Rocket stove makers are in love with secondary air. It's importance.... is less than 5%.
You have the cold air intake on te side off the inner tube. Not elbow, and this tube what you make is to large in diameter. Make a small cut from 8 cm bij 3mm . Then you get a turbo heater whit afterburner .
Might be worth a shot, but past experimenting with my rocket stove results in slowing the burn rate down, lowering the temperature of the exhaust because the added air took away from the initial draft. I did not see any difference in the exhaust (no smoke in my chimney before secondary air mod)
Let us know what your results are if you make this mod. Thanks!
Not working, and you get a lot off water in the stove.
