Abstract
A controlled kiln and manufacturing system for biochar production includes control systems and subsystems. An example controlled kiln () includes a drum (), a lid () and a floor () together forming a combustion chamber configured to contain feedstock for conversion into biochar. A catalytic converter () may be operatively coupled with an outlet of the kiln (). 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 (), a chimney () and smoke inlet pipes () enables regulation of smoke flow from a combustion chamber of the kiln while a heat exchanger () enables providing exhaust heat to one or more secondary applications.
