I was compelled to see how the burning process worked with the j channel and downward burn. I took a cinder block with two cores stacked on some concrete to allow an air path. I then covered the bottom with dirt and stacked a few more blocks on top, alternating to form the flue.
This thing could keep an amazing fire. It burned without smoke and could easily have been used for cooking.
I then extended the burn channel by capping the top of the first block and then brought the burn channel one core back. It burned well but not as the original and would go out if left unattended. The block temperature ranged from 180F to 250F with my infrared camera after about an hour of burning. CO was about 580ppm to 1080 while a clean burn was happening.
I learned this is a very practical way to have a small fire. The small woodstove in my house isn't really practical for temps above 40F since I have to burn enough wood to keep a bigger fire going. I have some infrared images I could post but the attachment button doesn't appear to work.
