The Department of Energy funded three years of R&D at ARC to create ‘Tier 4’ stoves. The new book has CAD drawings showing how to manufacture the stoves and many chapters describe how ‘Tier 4’ stoves function.
One of the 5 new stoves is a natural draft TLUD designed by Kirk Harris. The stove is shown in the video below. We helped him to tune the stove using the emissions hood. His stove stays clean burning at high and low power, doesn’t need a fan, and uses swirl to clean up emissions.
“Clean Burning Biomass Cookstoves” took us about a year to write. We hope you find it informative and useful!
