Open Source Fuel Agnostic Pyrolysis Batch Kiln

Basics

• A Pyrolysis Kiln that can use for heating:
  • A Gas Burner Torch
  • A Liquid Fuel Torch Babington Burner
  • An Electric Kiln Element
  • A Pellet Burner
  • The Ultimate System would use indrect heat (some sort of fluid, perhaps just heat the inert gas) to allow for easier swapping of modules, and even using more than one for quick fuel source swap)
• It uses some inert gas in to prevent oxidation such as:
  • Bottled nitrogen or argon
  • CO2 from bottles, or from a high-co2 source (such as filtered exhaust, or a bio-reactor)
• The Main Feedstocks Would Be:
  • Shredded Used Tires
  • Biomass
  • Shredded Plastic
  • Charcoal
• The main products it will produce are:
  • Pyrolysis Oil
  • Potentially a Pyrolysis Oil more similar to Bio-Crude
  • Syngas
  • Charcoal
• This will also serve as a testbed for a continous feed version

Basic "Hardware Store" or "Paint Can" Kiln

• It uses a paint can as the kiln, with metal tubing, mason jars, and metal wool as the other materials
• Atmospheric Cooled via air exposed metal pipe? (could also do water, ice, or ice+salt based cooling of the pipe, or stages with each?)
• Use either a T fitting, or just a 90* turn in the piping to dump the oil/syngas mixture into the mason jar
• Use either water in a "bubbler" setup, sawdust, metal wool, or some combination to seperare the oil from the gas stream
• Use a basic Rocket Stove to make the entire thing powered by Biomass
  • Later iterations can feed the Syngas back into a burner, rather than just using it in a Gas Flare
