A fire an inner chamber wall circumscribing and defining an inner chamber. A plurality of primary air apertures defined through the inner chamber wall at a first, lower level and a plurality of secondary air apertures defined through the inner chamber wall at a second, upper level. A fuel grate is supported within the inner chamber at a level between the lower level and the upper level. Solid fuel supported by the fuel grate, when combusted, is provided primary combustion air from below the fuel grate by the primary air apertures and provided secondary combustion air from above the solid fuel by the secondary air apertures, the secondary combustion air promoting combustion of unburned gasified combustibles rising within the inner chamber.

A grill apparatus includes a bottom portion, a lid portion, a firebox and an ash bucket. The lid portion is coupled to the bottom portion forming a cooking chamber. The bottom portion receives the firebox. A support structure of the firebox rests on an inner surface of the bottom portion. An inner surface of the bottom port, the support structure of the firebox and a firebox lower opening define a first air path from a lower portion of the cooking chamber to a heat chamber. The ash bucket includes an air vent extending from a base of the ash bucket base into an internal ash receptacle and has an upper vent aperture with a vent cover connected to the air vent. The cover is disposed over an upper vent aperture to further define the first air path.

The presently disclosed embodiments include a burner assembly for a cooking appliance that features a pullout including a removable burn pot. The pullout allows a user to easily remove the burn pot to empty burned ash and clean any residual materials from the burn pot. The pullout features a keyway design to aid in retention and easy removal from a cooking appliance. The pullout couples to a fuel chamber that houses an auger for supplying a fuel source and an ignitor. The pullout includes a gasket that provides a sealing engagement between the pullout and the cooking appliance.

Exemplary embodiments of a system and method for bimodal air control in a kettle-style grill are configured to be detachably mounted to the exterior of a kettle-styled grill such as, but not limited to, a Weber® charcoal grill. When mounted to the kettle-styled grill, a plenum-like component directs air flows to the interior of the grill's kettle via the kettle's lower body damper holes. A manually adjustable intake damper in the plenum component allows, restricts, or prevents a drawn ambient air flow into the plenum component. Separately, a forced air flow generated by a fan may also be provided into the plenum component. Adjustment of the intake damper may also adjust damper blades inside the grill's kettle. Ash that falls out of the kettle's damper holes falls through the plenum component and is captured in an ash receptacle that is removably mounted to the plenum component.

A heat reflective apparatus for use on the ground adjacent to campfires. The apparatus include a plurality of separate panels. Each of the plurality of panels are configured for vertical orientation and have a top edge and an opposing bottom edge defining a height and opposing side edges defining a width. A plurality of vertically oriented hinges, with each being connected to a side edge of two adjacent panels of the plurality of panels. This allows each of the connected adjacent panels to move between a collapsed position facing the other adjacent panel and an open position in relation with the other adjacent panel. At least two of the plurality of panels have at least one ground spike secured to the bottom edges thereof. The ground spikes are configured to secure the plurality of panels to the ground.

Embodiments of the inventive concept provide a high-capacity, sparkless, mobile, double-insulated wood pellet burner unit. The wood pellet burner unit is safely operated on a wood floor or deck. The wood pellet burner unit produces a large radiant flame that enhances the surrounding area, free from dangerous sparks and smoke. The ash and coals from the fire are enclosed within a double-insulated housing. A wind break radiant heat reflector protects the flame from being distorted, enhances the flame so that it remains in a substantially upright column, and reflects some of the heat outwardly toward the users. Casters disposed on the bottom of the wood pellet burner permit easy and convenient movement of the unit. The wood pellet burner unit disclosed herein produces a larger and fuller flame than a pure gas fire pit based on a balanced multi-directional flow of heated combustion air flow through the unit.

A cooking apparatus having a cooking chamber, a cooking drawer, a solid fuel support drawer, gas burners, and an ash drawer. One of the cassettes positionable in the cooking drawer can be a belt conveyor which can transport food between end doors of the cooking chamber. A front door of the chamber, when open, allows for the cooking drawer with a partially-cooked food item to be removed and moved to another location for inspection/manipulation of the food item, and then returned to the cooking chamber. Infrared burners on the ceiling of the cooking chamber are directed down to the cooking drawer. Hot exhaust gases in the cooking chamber pass through the housing to a top area for food cooking/warming. A flickering flame assembly creates flickering flames in the back of the chamber which are visible from both the front and the back of the cooking apparatus.

The present disclosure provides an air conditioner system and a control method for the same. The air conditioner system includes: a refrigeration system. A first port of a second four-way valve is connected to a pipeline between the first four-way valve and the indoor heat exchanger, and a second port of a second four-way valve is connected to a first position in a pipeline between the indoor heat exchanger and the outdoor heat exchanger. A first port of the first passage of an auxiliary heat exchanger is in communication with a fourth port of the second four-way valve, and a second port of the first passage is connected to a second position in a pipeline between the indoor heat exchanger and the outdoor heat exchanger.

A combi stove (1) is arranged for combusting both logs and granular material. The combi stove (1) has 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 has an ash collector (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) has 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). The granular material combustion area (5) is at least partly surrounded by a granular material area sidewall (8) having 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). 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).
