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.
Claims11
A heat recovery system, comprising:
- at least one biochar kiln having a combustion chamber;
- a chimney having proximal and distal ends and being configured to exhaust smoke from the combustion chamber between the proximal and distal ends;
- a secondary subsystem;
- a heat exchanger configured to recover heat from the chimney and provide the heat to the secondary subsystem;
- a controller configured to maintain an optimal mixture of smoke and air in the chimney.
