I realize there are lots of ways to make charcoal - but we are under a burn ban where I live and no hopes of it lifting anytime soon. I have an old, fairly large ceramics kiln with a PID controller and was considering setting it up inside my welding shop to make charcoal using steel paint cans. The electrical demand cost will be more expensive than a brush pile outside but less than propane.
I can also control the temp within a reasonable range - figure the worst that can happen is to smoke up the fire brick inside the kiln. The lid can also be propped open to let the smoke out; I can run a high fire cycle every so often and burn that out, if the soot becomes excessive.
Has anyone done this or see a problem with this concept?
