A heating appliance (1) comprises a main body (2) having a fire-box (9) with an opening (10) for placing combustible fuel (11) therein with which the heating appliance (1) is used. The heating appliance (1) has a fire door (3) for closing the opening (10), and a movable baffle (4). The baffle (4) is placable in a first position in which it is disposed in a front part of the fire-box (9), it is behind the fire door (3), and it forms a shield for the combustible fuel (11).

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.

The Accelerated Slow Roasting Apparatus is a device for slow-and-low cooking a whole previously butterflied-prepared animal carcass comprising a closed cooking chamber with a plurality of adjustable air vents arranged on the bottom edge of said cooking chamber and a plurality of adjustable opening vents on a vertical side of the lid of said cooking chamber, and a slide out cooking grate with adjustable rails to support the grate while out of the cooking apparatus, a plurality of removable cooking fuel trays, wherein said cooking grate is positioned between twenty-five and forty centimeters above said cooking fuel trays to enable a flame-flare-up free, time-accelerated, slow-and-low cooking of said animal carcass in half, or less than half, of the traditional sixteen to twenty-two hours cooking time.

Combustion appliances for providing heat for cooking meats and other foods are provided. The appliances are self-stoking, in that they do not need to be repeatedly re-filled with more fuel periodically, such as during an 18-hour slow cook procedure. A venturi assembly is provided which consists of a venturi duct and baffle, which creates a higher flow, lower pressure region within the venturi assembly, which gases mix with spent combustion gases to provide a more uniform temperature output.

A cooking grill with a cooking chamber, pellet fuel combustion unit, and ash cleanout system for releasing retained ash from the combustion unit through an access door without requiring the disassembly of the upper components of the grill. The combustion unit has a first end with a first end opening, and a second end with a second end opening. The ash cleanout system includes an access door adjacent to the second end, operable by a user from a position external to the cooking chamber through a pull link, and capable of a first position wherein the second end opening is closed to generally retain ash within the pellet fuel combustion unit, and a second position wherein the second end opening is open to release the retained ash to a separate removal location.

A fire display fire pit for burning pelletized fuel and associated components and methods. The fire display pit can include a conveyor for moving pelletized fuel from a hopper to a burn chamber. The fire pit may be configured to produce flames in a vortex pattern, such as inside a flame tower.

Disclosed herein is a self-assembly brazier. The self-assembly brazier includes: a pair of floor plates arranged bilaterally symmetrical to face each other; a pair of side wall modules having a plurality of side panels disposed to be rotatable, being combined with each other to face each other symmetrically so that a combustion space is formed, and being arranged on upper surfaces of the floor plates to be erected; and a pair of fuel loading parts seated inside lower portions of the side wall modules so that fuel is loaded on the upper surfaces of the fuel loading parts.

A heating appliance (1) comprises a main body (2) having a fire-box (9) with an opening (10) for placing combustible fuel (11) therein with which the heating appliance (1) is used. The heating appliance (1) has a fire door (3) for closing the opening (10), and a movable baffle (4). The baffle (4) is placeable in a first position in which it is disposed in a front part of the fire-box (9), it is behind the fire door (3), and it forms a shield for the combustible fuel (11).

The invention relates to a tubular boiler with a heat exchange tube with at least one helical layer situated in a heat exchange chamber, and which includes a set of laterally joined spirals. The boiler includes, an inner side of the helical layer, an oven that is rigidly joined to said layer and connected to a feeder by means of which fuel is supplied. The boiler also includes an output collector for collecting ash and slag, which connects the inside of the heat exchange chamber to the outside of the boiler, and a forced-air-current generator that generates a movement of air inside the boiler and directs it to the oven. This movement of air moves the ash and slag along the at least one helical layer to the output collector.

A pellet stove includes: a furnace; a burner disposed in the furnace, a top of the burner being open; and a feed opening provided at a first sidewall of the burner. A through port for air intake and ash falling is provided at an underside of the burner. A grate supporting pellet fuel is provided above the through port. Auxiliary supports for sustaining bottom fire are disposed under the grate. The auxiliary supports are arranged higher than the through port, and the auxiliary supports are located at a side below the feed opening and cover an area not exceeding 1/2 of the area covered by the grate.
