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.
Claims10
An exhaust system for a biochar kiln, comprising:
- a chimney of the biochar kiln;
- a first forced air inlet on the chimney to draw smoke through the chimney during a preheating stage to prime the chimney, the first forced air inlet being connected to a first blower;
- a second forced air inlet operatively coupled with the chimney, the second forced air inlet being connected to a second blower,
- wherein the second blower is activated to increase airflow when air naturally occurring in a smoke stream in the chimney is insufficient, the second blower deactivated when there is sufficient air;
- and
- both a temperature sensor and an oxygen sensor with feedback to a controller,
- wherein the controller activates and deactivates the first blower and the second blower based on input from the temperature sensor and the oxygen sensor.
