5 Gallon (22-liter) TLUD Stove for Biochar

Paul Anderson, 2009 SeaChar Stoves Workshop

The efforts at SeaChar (Seattle Biochar Initiative) produced a 5-gallon (22-liter) TLUD.

"On Saturday, August 1, Seachar hosted Dr. Paul Anderson (Dr. TLUD) for an all-day workshop in the construction of Top-Lit Up Draft (TLUD) cookstoves. The stoves can quickly be constructed from commonly available materials, and produce charcoal while providing heat for cooking (or other uses). Paul’s TLUD stoves have been tested and shown to produce very low emissions of CO and particulates. The stoves can provide benefits wherever people rely on biomass for cooking. TLUD stoves use a wide variety of small pieces of biomass for fuel. The clean burn greatly improves indoor air quality compared with open burning and many other types of stoves. In addition, the charcoal can be used as biochar to improve soil fertility, sequester carbon, and potentially provide a source of income through carbon credits."

The focus was for making biochar, but this size of TLUD will be highly appropriate of institutional-size cookstoves in the developing countries.
