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.
Claims3
A method for producing pieces of biochar, the method comprising:
- A) burning biomass in a firebox to produce biochar, wherein the biomass is supported in the firebox by a table having at least one opening;
- B) cyclically moving the table in a horizontal plane relative to the firebox to cause pieces of the biochar to fall through the at least one opening;
- C) automatically conveying the pieces of biochar to a drainage basket removably received by a quenching reservoir pan containing a quenching liquid;
- and
- D) removing the drainage basket containing the pieces of biochar from the quenching reservoir pan.
