Two Themes• Large TLUDs for making charcoal
in Cambodia
• Biochar research results of T. R. Preston and the LRRD, Colombia

Charcoal Production in
Large TLUD Pyrolyzers in
Cambodia
Fuel is coconut shells, that are crushed, and later loaded into large TLUD devices.

TLUD Pyrolyzers with 15 inch Inside Diameter for Fuel.
Large blower circulates the hot exhaust gases through a tunnel for drying the charcoal briquettes.
