Abstract
An example exhaust system for a biochar kiln includes a chimney of the biochar kiln. The example exhaust system for a biochar kiln also includes a first forced air inlet on the chimney to draw smoke through the chimney during a preheating stage to prime the chimney. The example exhaust system for a biochar kiln also includes a second forced air inlet operatively coupled with the chimney. The second forced air inlet activated to increase airflow when air naturally occurring in a smoke stream in the chimney is insufficient, the second forced air inlet deactivated when there is sufficient air.
