Abstract: A biochar apparatus has a firebox for containing biomass to be incinerated to produce biochar, a pair of biomass supporting panels arranged in the firebox in a V-shaped configuration and separated by an extraction gap between lower edges of the panels, a roller system arranged to support at least one of the panels for rolling movement relative to the firebox, an actuator operable to move at least one of the panels relative to the firebox upon the roller system, and a conveyor system under the extraction gap, wherein pieces of the biochar pass through the extraction gap to the conveyor system, and the conveyor system is operable to convey and discharge the pieces of biochar. The panels may include refractory material capable of withstanding high temperatures associated with incineration of biomass in the firebox. These panels also protect the conveyor system and its components from incineration heat.

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.

Abstract: A heat capturing module for obtaining useful energy from waste heat includes an extendable hood directing hot gas through a heat exchange assembly having a plurality of heat pipes. A closed flow loop directs a heat transfer medium through the heat exchange assembly to heat the heat transfer medium, and directs the heated medium for use by an application. In one embodiment, the closed flow loop directs the heat transfer medium through an organic Rankine cycle unit where heat is converted to electrical power. An exhaust system having a variable-speed induction fan induces flow of the hot gas through the heat exchange assembly. The speed of the induction fan may be controlled to maintain a setpoint temperature of the heat transfer medium. The hood may be extended and retracted based on a measured temperature of gas at an intake region of the hood. The module is transportable by truck trailer.

Abstract: The present invention is a portable incineration apparatus. The portable incinerator includes a box having four walls with a top and bottom opening. The inside of the walls are lined with a layer of refractory material to form a combustion chamber in combination with the bottom opening which is placed on the ground. A source of high velocity air is in communication with a manifold assembly which is adapted to direct an effective sheet or curtain of high velocity air across the top opening and down into the combustion chamber to maintain a substantially uniform discharge rate of the high velocity air as it exits the manifold assembly along the top opening. The uniform curtain of air over the top opening limits the amount of smoke, ash and other particulate released into the atmosphere during the burning process.
