Yup, but why? Just burn all the wood in a single burn tube. The oxygen fed in at the bottom will be consumed before it can get very far. All the heat is now just simply applied directly tlo the fuel verses heating a vessel.
This is one of those things it is so simple to do our complex minds will not except it and we must make it more difficult and complex to make our brains happy.
Create fire in a tube and make charcoal. Use the heat the best you can. Create water drip and a gasifier that you can run a mixture of raw wood in with your charcoal. If all are achieved you will have a more practical and efficient system than you can otherwise.
Yeah Im one of those people. Too simple to comprehend, me brain no compute
