Abstract
A controlled kiln and manufacturing system for biochar production includes control systems and subsystems. An example biochar kiln exhaust apparatus, includes a chimney configured for heating by pyrolysis and for exhausting smoke from the combustion chamber. The example biochar kiln exhaust apparatus also includes a plurality of exhaust inlet pipes configured to pass smoke from the combustion chamber to the chimney.
Claims20
A biochar kiln exhaust apparatus, comprising:
- a chimney configured for heating by pyrolysis and for exhausting smoke from a combustion chamber;
- and
- a plurality of exhaust inlet pipes configured to pass smoke from the combustion chamber to the chimney, the exhaust inlet pipes spaced substantially evenly around a base of the combustion chamber to balance air intake from a plurality of air inlet ports of the combustion chamber and direct exhaust from the combustion chamber and toward the chimney.
A biochar kiln apparatus;
- comprising:
- a combustion chamber;
- a chimney configured for heating by pyrolysis and for exhausting smoke from the combustion chamber;
- a plurality of exhaust inlet pipes configured to pass smoke from the combustion chamber to the chimney, the exhaust inlet pipes spaced substantially evenly around a base of the combustion chamber to balance air intake for the combustion chamber and direct exhaust through the combustion chamber and toward the chimney;
- and
- a first forced air inlet on the chimney with a blower operable to blow air into the chimney and draw air through the chimney.
