A system includes a cooking chamber defining a space for food to be cooked, a firepot inside the cooking chamber that is configured to utilize pelletized fuel to provide heat or smoke within the cooking chamber for cooking the food, and a fuel hopper defining a storage space for the pelletized fuel before delivery to the firepot. A battery powered auger interposes the fuel hopper and the firepot and is configured to selectively convey the pelletized fuel from the fuel hopper to the firepot for combustion. A rechargeable battery selectively provides power to the auger.

A burner for solid particle fuels such as shavings or pellets. The invention includes a helical piston to deliver fuel particles up an inclined tube into a cup having an oxygen delivery tube for combustion. The helical piston is axially extendable and retractable to first advance material up the tube without rotation, and then retract with rotation so as to screw itself into the next charge of material to be advanced. Combustion heat may be used to drive a Stirling engine or other mechanism for converting heat into other useful energy or power, such as using the burner as a component of a combined heat and power (CHP) system.

A cooking device is provided herein that includes a trailer having one or more frame members and configured to couple with a vehicle. A housing is supported by the frame members and defines a heating chamber. A heat source is disposed within the heating chamber. A controller is operably coupled with an auger assembly to direct fuel to the heat source for heating the heating chamber. A power actuator is operably coupled with the controller and configured to accept electrical power from two or more power supplies and provide power to the controller from one of the two or more power supplies.

A fuel management system for a biomass furnace features a common drive motor operatively coupled to both a fuel delivery conveyor, which is arranged to support and displace fuel during combustion in a combustion chamber of the furnace, and an ash removal conveyor which is arranged to transfer ash generated by the combustion out of the combustion chamber. The system also features ducting which extends around the fuel delivery conveyor to convey airflow generated by a blower for subsequent discharge both below and above the fuel during combustion. Furthermore, the system features a housing which operably supports at least the fuel delivery conveyor and which is arranged to be removably insertible into the combustion chamber of the furnace.

Furthermore, a use of a stove (1) is disclosed.

A burner for solid particle fuels such as shavings or pellets. The invention includes an auger to deliver fuel particles up an inclined tube into a cup having an oxygen emitting orifice for combustion. The auger is axially extendable and retractable to first advance material up the tube without rotation, and then retract with rotation so as to screw itself into the next charge of material to be advanced. Combustion heat may be used to drive a Stirling engine to comprise a combined heat and power (CHP) system.

Flue gases may also be condensed onto chilled objects as beneficial ceramic-like coatings, or these objects may be made of frangible or soluble material so that the condensate may be collected separately as a valuable ceramic-like material.

Disclosed is a combi stove (1) arranged for combusting both logs and granular material. The combi stove (1) comprises a common combustion chamber (2) arranged so that both the logs and the granular material may be combusted in the common combustion chamber (2). The combi stove (1) further comprises ash collecting means (3) arranged under the combustion chamber (2) and a front aperture (4) through which logs may be placed in the combustion chamber (2). Also the combi stove (1) includes a granular material combustion area (5) arranged in the combustion chamber (2), wherein the granular material combustion area (5) comprises a bottom combustion surface (6) including bottom airflow apertures (7) arranged to enable an airflow to the granular material during a combustion of the granular material in the granular material combustion area (5), wherein the granular material combustion area (5) is at least partly surrounded by a granular material area sidewall (8) comprising sidewall airflow apertures (9) arranged to enable an airflow to flue gasses generated during a combustion of the granular material in the granular material combustion area (5), and wherein at least a part of the granular material area sidewall (8) is releasable from the granular material combustion area (5). Furthermore, a use of a combi stove (1) is disclosed.

The invention discloses a mobile pellet fueled variable frequency barbecue oven as well as an electric cabinet assembly and a control circuit thereof, and relates to the field of vehicle-mounted barbecue ovens. The mobile pellet fueled variable frequency barbecue oven includes a chassis assembly, wherein the chassis assembly is connected with an automobile; a cabinet arranged above the chassis assembly, wherein the cabinet consists of a lower cabinet and a fuel tank assembly which are arranged oppositely, and is provided with a barbecue oven cavity for accommodating a food grate; and an electric cabinet assembly, wherein both sides of the electric cabinet assembly are electrically connected with the cabinet and the automobile power supply respectively to provide working power for the barbecue oven and control stable power supply of the barbecue oven. The mobile pellet fueled variable frequency barbecue oven as well as the electric cabinet assembly and the control circuit thereof replace a power supply assembly and a circuit of a traditional vehicle-mounted electric barbecue oven through a low voltage actuator, thus realizing low power operation of the vehicle-mounted barbecue oven, realizing normal work during movement of the vehicle, broadening the applicable scenarios of the vehicle-mounted barbecue oven, and being more suitable for actual use requirements.
