Abstract
A biochar apparatus and a related biochar module may have a horizontal table-shaking mechanism and a tapered channel for causing biochar pieces generated in a firebox to fall through openings in the table to a conveyor system below. The table may be configured with replaceable grate panels. A quenching reservoir pan for holding quenching liquid receives a drainage basket at a discharge end of the conveyor system for quenching hot pieces of biochar and allowing easy retrieval of the quenched pieces.
