Presentation Transcript

  1. Updates on Biochar Issues and Gasifier Stove Technology Presentation to Illinois Biochar Group 5 April 2013 Paul S. Anderson, PhD “Dr TLUD” psanders@ilstu.edu Chip Energy, Goodfield, IL

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

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

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

  5. Removal of the Hot Charcoal

  6. Extruding Briquettes,onto Drying Racks, and in a Charcoal Stove

  7. Acknowledgement • The following Power Point Slides were prepared by T. R. Preston and delivered as part of his presentation to the Biochar Conference in Siem Reap, Cambodia, in March 2013. • Dr. Preston has given permission to re-show these slides. • His references are provided at the end. • Questions concerning this material should be directed to Dr. Preston.

  8. Production and use of biochar in integratedfarmingsystems T R Preston FincaEcologica, AA48 Socorro, Colombia preston@lrrd.org

  9. The strategy to sequester carbon in the soil

  10. Thegasifierstove (Paul Olivier)

  11. Biocharand biodigester effluent on growth of maize Rodríguez et al 2009

  13. Root development in the subsoil with and without biochar and effluent

  14. Effect of biochar on soil pH

  15. Charcoal Control Biochar
