Dear list members, I plan to make a retort for producing charcoal. As may be you know, there is a great amount of pyrolysis gas resulting from the process. One can use this gas in order to get more heat that is needed in the process, adding it to the basic fuel used. Does anyone have an idea on the most efficient gas burner type for me to use? Thank's.
