Wayne S. Teel, Journal of Agricultural Science and Technology A 2 (2012) 1332-1343

Describes a project to develop a small-scale biochar making burner that would also provide heat for a greenhouse and domestic water heating. The project was eventually successful, with an efficient burner producing good quality biochar and a fair amount of heat.
