Airflow control and heat recovery in a managed kiln

Abstract

A controlled kiln and manufacturing system for biochar production includes control systems and subsystems. An example controlled kiln (100) includes a drum (200), a lid (120) and a floor (250) together forming a combustion chamber configured to contain feedstock for conversion into biochar. A catalytic converter (700) may be operatively coupled with an outlet of the kiln (100). A monitor and control subsystem may be operative to issue notifications or automatically end biochar conversion. A ventilation and exhaust system including independently controllable air inlet ports (240), a chimney (300) and smoke inlet pipes (330) enables regulation of smoke flow from a combustion chamber of the kiln while a heat exchanger (1000) enables providing exhaust heat to one or more secondary applications.
