• Gasifier construction set: [1]
• Mike Koch's gasifier, U. Missouri, Columbia, 2008 Capstone Project, Mechanical Engineering: [2]
• A gasifier can also be used to make biochar. Here are some simple design examples for charcoal/biochar-producing biomass gasifiers:
  • 50 kilowatt wood pellet gasifier
  • Charcoal kiln at A.R.T.I.
  • Folke Günther's design: "the simplest of the simple - a two-barrel charcoal retort"
  • Tom Reed's TurboStove

Ben's gasifier - not open source, though

Conversation with Ben Hansen

• Ben is building a 40 kW gasifier CHP system, and may be interested in a steam engine
• Packed bed, downdraft:
• Modified fluidyne gasifier.
• Doug Williams – fluidyne gasifier - http://www.fluidynenz.250x.com/
• Fab shop in Viroqua – friend of Ben – Roger Tullifson, Tollifson repair– did a heat exchanger for diesel exhaust.
• Dig up solenoid valves contact – some open source people
