I made this one to use wood pellets and twigs. It has a stainless steel wall protector in the fire box area. I added a stainless steel tube in the center for increased air intake for the pellets to be completely consumed, didn’t want any biochar remaining.
I boiled 4 cups of water with one cup of pellets in about 13 min.
