How To Make Biochar In A Burn Barrel. This will force the fire in the barrel to get oxygen from the other side of the retort, causing it to move that direction. Two years ago, i taught my 7th grade class how to make biochar using the instructional materials found here.
The 500 series batch kiln is a commercial unit that produces up to 750 kg of biochar per burn. The kiln consists of two kiln bodies (retorts) with a capacity of 6 cubic meters each, and a central combustor or burner that provides heat to both. The kiln is built in to a 20 ft container which allows it to be transported anywhere a truck can reach.
I make no claims to being an expert on making biochar and i am still learning and tweaking as i go along, but this is the current.

This is the chemical process which occurs in material which contains carbon (such as wood) when it is heated with minimal oxygen.
