A combustion chamber has an inner wall defining an inner chamber. The inner wall is perforated to admit combustion air into the inner chamber. The combustion chamber has an outer wall defining an outer chamber. The outer wall is perforated to admit combustion air from a pressurized air plenum to the inner wall. The inner and outer wall are spaced apart such that air may flow between the inner and outer walls.

A stove using biomass pellets as fuels is disclosed herein, comprising a stove body that comprises a firebox, at least one hopper, and a feed tube, wherein the at least one hopper is connected to the firebox via the feed tube, and fuels contained inside the at least one hopper can enter the firebox along the feed tube under gravity. The stove has a simple structure and removes any mechanically or electrically controlled feeding system by feeding the firebox using gravity of the fuels, therefore lowers the cost.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a burn pot including an upper end having a first opening, a lower end located opposite the upper end and having a second opening, and a sidewall extending between the upper and lower ends. The example pellet grill further includes a fuel grate positioned within the burn pot between the upper and lower ends. The fuel grate is configured to support pellet fuel within the burn pot. The fuel grate includes a plurality of ash openings dimensioned to enable ash produced from combustion of the pellet fuel to pass downwardly through the fuel grate toward the second opening.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a main body defining a cooking chamber. The example pellet grill further includes a grease deflection bar assembly located within the main body. the grease deflection bar assembly includes a first rack removably positioned on first tabs of the main body, a second rack removably positioned on second tabs of the main body, and a grease deflection bar extending between and removably positioned on the first and second racks.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a main body defining a cooking chamber. The main body includes a first opening extending through a bottom portion of an outer wall of the main body. The main body further including a grease channel formed along the bottom portion of the outer wall and extending to the first opening. The example pellet grill further includes a burn pot located within the main body. The burn pot includes a lower end having a second opening aligned with the first opening. The second opening is configured to enable pellet fuel ash to pass downwardly from the burn pot onto an ash slide positioned below the second opening. The example pellet grill further includes a waste collection drawer located below the main body. The waste collection drawer is movable relative to the main body between a closed position and an open position. The waste collection drawer includes a grease bin positioned below the first opening and configured to receive grease from the grease channel when the waste collection drawer is in the closed position. The waste collection drawer further includes an ash compartment positioned below the ash slide and configured to receive pellet fuel ash from the burn pot, via the ash slide, when the waste collection drawer is in the closed position.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes an auger and an auger motor operatively coupled to the auger. The example pellet grill further includes one or more processors configured to determine whether the auger is jammed. The one or more processors are further configured, in response to determining that the auger is jammed, to command the auger motor to modify a direction of rotation of the auger.
