Giant Ring of Fire Kiln Eats Smoke

We used 5 sections of sheet steel (44" x 86" with 2" flanges) bolted together to surround a large slash pile. All the combustion air comes in from the above. This counter-flow combustion pulls smoke down into the flame where it burns for clean combustion. At the end, we quench with water and make biochar

upcoming events

March 7-8: Biochar Course at Siskiyou Field Institute

During this two-day workshop you will learn how charred biomass (biochar) made from non-merchantable woody residue left from logging and pruning operations can increase soil productivity, promote beneficial soil microbes, reduce wildfire risk, decrease emissions, and slow climate change.  Mechanical engineer Kelpie Wilson and forest ecologist Ken Carloni will give an overview of the history and science of biochar production and use during classroom presentations.  In the afternoons, we’ll explore small to large-scale biochar production theory and practice.  On Day 2, we’ll apply that theory in a hands-on demonstration of loading, firing and quenching in a variety of kilns for producing biochar in the field. Siskiyou Field Institute  is located at the Deer Creek Center, 1241 Illinois River Road, Selma, OR 97535
