The invention relates to a combustion device for burning fuel such as wood, wood chips, wood pellets, or the like, wherein the combustion device comprises a first chamber and a second chamber, wherein the second chamber is arranged underneath the first chamber and the first chamber receives the fuel, wherein the first chamber comprises, at the bottom, an intermediate layer of combustible material which holds the fuel in the first chamber as long as the intermediate layer is not damaged or destroyed by combustion and such that, following damage to or destruction of the intermediate layer, fuel located in the first chamber falls into the second chamber, wherein, during the combustion process in the first chamber, substantially gas combustion is caused and, after the fuel has been conveyed into the second chamber, coal burning preferably occurs, or the fuel may be removed from the second chamber through an opening.

A cooking appliance is disclosed including a burner assembly that effectively and efficiently combusts fuel and directs the resulting smoke from a burn pot of the burner assembly to a cook chamber of a cooking appliance. The burner assembly may include a series of openings and curved faces that provide airflow to push smoke from the burn pot to the cook chamber and provide more turbulence and better heat and smoke circulation in the smoker. The burn pot may define one or more vents and include a one or more curved or shrouded surfaces. The burner assembly may include one or more deflector plates configured to direct the flow of smoke from the burn pot to the cook chamber.

A small stove assorted with smokeless combustion of combustible solids/semisolids, a stove core and a shape of briquette are to ensure that a cylindrical briquette stack is quickly ignited in a smokeless state. A section A stove core inner ring and a flame concentrator are made of a selected high-whiteness aluminum silicate fiber with superior thermal insulation/resistance effects, and are processed for, e.g., blocking the micropores inner circumferential surface, and a stove core outer ring is made of cheaper foam glass, foam ceramic or calcium silicate modules. An underlying briquette with a concave top is designed to enable an easy, convenient and fast alignment of vent holes. The overall cross-sectional area of the vent holes is expanded by 30%-50% as compared with the area of the anthracite briquettes with the same diameter, and the inner ring vent holes are mainly expanded.

This invention “Optimized Biomass Combustion (Burning) for Renewing Ecosystem, Environment, and Atmosphere” is a process in which pure cow ghee is burned using sticks of specific trees along with other biomass such as dried cow dung cakes, grains, metal dust, herbs, etc., in a specially designed open brazier (combustion chamber). The amount of ghee, biomass, dimensions of the combustor, and length of time depends on the purposes that are given below. Reduce indoor air pollution and outdoor (ambient) air pollution caused by vehicles, and industries. Reduce rainwater and waterbodies pollution, curtail agriculture soil pollution. Mitigate intensities of hurricanes, storms, and tornadoes. Recovery from droughts, suppression of forest wildfires, mitigate virus/bacteria count, increase immunity, and reduce mosquitoes (and mosquito eggs) in the proximity.

A method for operating a combustion arrangement, the combustion arrangement including at least one combustor chamber arranged in a double-walled housing, at least one inlet configured to supply a fuel to the at least one combustion chamber, at least one outlet for letting exhaust air from the at least one combustion chamber, and at least one air channel configured to feed supply air into the housing, wherein the housing includes an inner wall and an outer wall which jointly define an intermediate space between each other, wherein an air inlet opening that cooperates with the at least one air channel is arranged in an upper end section of the outer wall so that the supply air is feedable through the at least one air channel into the intermediate space.

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.

Embodiments of a cooking station for cooking a food product are provided. In one embodiment, the cooking station includes a main body and an insert. The main body includes a vertically extending wall extending between a closed bottom end and a closable upper end with a lid. The main body is configured to extend longitudinally in a vertical orientation. The main body defines a lower insert opening and an upper insert opening, the main body including a slideable door moveable to close-off either the lower and upper insert openings. The insert is sized and configured to be removably positioned through either one of the lower insert opening and the upper insert opening, the first insert having heating element container structure configured to deliver heat to the food product.

A portable camping stove/fire pit has a cylindrical combustion chamber having a bottom member and circularly configured vertical side wall which extends upwardly from the bottom member and terminates in a top edge. The circularly configured side wall has a plurality of spaced apart vertically oriented slots, where each of the slots extends from the exterior of the combustion chamber into the interior. The circularly configured side wall has a plurality of vertically aligned louver members disposed in a spiraling configuration about the combustion chamber, where each louver is disposed tangentially to a respective vertical slot. During combustion within the combustion chamber, a flow of air is drawn past the plurality of vertically aligned louver members, through the slots into the interior, thereby forming a vortex as combustion occurs within the combustion chamber.

The present disclosure belongs to the technical field of the combustion heating stove, and disclosed is a stove including a stove body, an air inlet channel and an exhaust channel. When the stove body is used in an enclosed space, an air inlet end of the air inlet channel is in communication with an outside of the enclosed space, a connection end of the air inlet channel is in communication with an air inlet of the stove body, the air inlet channel is operative to introduce air into the stove body from the outside of the enclosed space; and a connection end of an exhaust channel is in communication with an exhaust port of the stove body, an exhaust end of the exhaust channel is in communication with the outside of the enclosed space, whereby the exhaust channel is operative to discharge exhaust gas in the stove body out of the enclosed space.
