Abstract
A biochar kiln is disclosed. An example of the biochar kiln includes a kiln body having a sidewall, a floor attached to the sidewall, and a removable lid. The example biochar kiln also includes a plurality of semi-independent combustion cells. The example biochar kiln also includes an outside vent pipe loading to a center of the semi-independent combustion cells to provide combustion air.
Claims17
A biochar kiln, comprising:
- a kiln body having a sidewall, a floor attached to the sidewall, and a removable lid;
- a plurality of combustion cells;
- a plurality of outside vent pipes each connecting to a center of a respective one of the combustion cells to provide combustion air;
- a plurality of thermowell tubes built into the floor of the kiln body for each of the combustion cells, wherein at least one of the thermowell tubes is positioned substantially in the center of the floor.

A biochar kiln, comprising:
- a kiln body having a sidewall, a floor attached to the sidewall, and a removable lid;
- a plurality of semi-independent combustion cells including at least a center combustion cell in a center of the kiln body and perimeter combustion cells between the center combustion cell and the sidewall of the kiln body;
- an outside vent pipe in a center of each of the perimeter combustion cells, the outside vent pipe linking to a center of the semi-independent combustion cells to provide combustion air;
