A domestic home gas cooktop is provided. The cooktop has a top sheet having a primary combustion air hole through the top sheet; a gas burner cup mounted to the top sheet; and a gas burner base mounted to the burner cup. The primary combustion air hole is configured to allow first primary combustion air to flow from beneath the top sheet to the burner base, and the primary combustion air hole is located remotely from the burner cup.

According to one embodiment a gas burner assembly is provided that includes a gas burner having a burner body. An injector fluidly coupled to a gas conduit is oriented towards the gas burner. A burner holder that is configured to support the burner body includes two independent parts, a burner base and an injector base located below the burner base, the burner base being coupled to the burner body. The burner base includes a hole that fluidly communicates the burner body with an injector located in the injector base. The burner base compatible with a specific type of gas burner and the injector base being compatible with a plurality of types of burner bases.

A heating assembly for a cooking device is provided herein. The heating assembly may include a burn box having a body defining a pot and a receptacle. The pot and receptacle can be separated from each other by a divider. An ignitor extends into the pot. A duct is fluidly coupled with the receptacle and is configured to extend between the receptacle and a housing surrounding the burn box. The duct defines an inlet within the receptacle and an outlet on the opposing end portion of the duct.

The invention relates to a burner housing for a pellet grill having two or more elongated apertures configured to have a first end with an adjacent first width and a second end with an adjacent second width, the adjacent second width relatively greater than the adjacent second width. The burner housing generates an air vortex when in burner operation in such a manner as to provide relatively more air movement in an area somewhat distal to the burner, thereby retaining an optimal amount of ash during lengthy cooking cycles while also providing optimal fuel-to-air characteristics.

A combustion air proving system is provided for a burner assembly having a burner for providing heat to a location, a controller, and a back plate. Outside air is fed to the burner via a conduit, and is connected to an inlet of the system. An outlet of the system is connected to the burner via the back plate. A damper within the system is translatable between open and closed positions for allowing and blocking air flow, respectively. A sensor measures an air flow parameter of air flow to the burner. The sensor communicates with the controller, which shuts down the burner if the parameter measured by the sensor meets a predetermined threshold value. An assembly installer may test for proper sensor and controller functions by translating the damper to the closed position and blocking outside air flow.

A combustion air proving (CAP) system for a burner assembly having a burner for providing heated air to a location, a controller, and a back plate, where outside air is fed to the burner via a conduit. The CAP system is connected to an inlet of the system. An outlet of the system is connected to the burner via the back plate. A damper within the system is translatable between open and closed positions for allowing and blocking air flow, respectively. A sensor measures an air flow parameter of air flow to the burner. The sensor communicates with the controller, which shuts down the burner if the parameter measured by the sensor meets a predetermined threshold value. An assembly installer may test for proper sensor and controller functions by translating the damper to the closed position and blocking outside air flow.

This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.

Disclosed is a wind-resistant heating device using a non-electric source. To this end, a non-electric heating body is received in the inner lower part of a main casing of a wind-resistant heating device. Air supply holes for supplying air for combustion are formed in the main casing. An upper opening for upward discharging heat generated when the non-electric heating body is combusted is formed in the main casing. Wind-resistant casings are spaced apart at a specific interval on the inside or outside of the main casing, thus preventing a head wind from flowing into the air supply holes of the main casing. Accordingly, although a head wind flows into the air supply holes of the main casing or the heating device is carried and moved, air can be changed into a flow of air to enable continuous combustion.
