Gasifier Burner/Research Development

Overview

Design Criteria

The gasifier should be designed in such a way that it can satisfy a specific set of use cases. These use cases should consider the availability of three products produced by the gasification process, namely Heat, Ash or char and combustible gases.

Use of excess heat:

• heat air in a shelter
• dry fuel for the gasifier

Use of ash and char:

• soil amendments
• lye production for:
  • soap products
  • lye stabilized earth

Use of combustible gases:

• Steam Generator
• Steam Engine (possibly in tandem with Steam Generator)
• Cement Mixer Cement Mixer
• Power Cube Power Cube
• Truck
• Car
• Kiln

Portability

Unit should be available in both portable and fixed arrangements. portable configurations should enable vehicle (trailer?) mounting.

Modularity

A good design should allow for flexibility in design variability without loosing compatibility between the various components. This need may be more pronounced during development. modules include:

• fuel bin
  • different Sizes
  • Autoloading? (designed with this in mind not necessarily needed)
• reactor core and ash collection
  • variability in configuration depending on feedstock
  • hearth material may vary depending on portability
• cyclone filter
• gas cooler
• filters
• manifold (optional)
• flare

Capability

How large an engine should this unit supply?

Research

• 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
