A powder coated aluminum barbecue pit burner that burns gas in the same way that stainless steel burner tubes do, but last longer and do not rust. The use of powder coated aluminum makes the burner according to the present invention corrosion resistant. Additionally, the powder coated aluminum burner of the present invention also contain a heat sink element that prevents the temperature of the tubes from getting too high. Controlling temperature and using powder coated aluminum burners, instead of stainless steel, ensures that the burner will last longer. Another embodiment utilizes a water cooled system in connection with the heat sink element.

A burner assembly includes a spreader and a burner cap coupled to the spreader. The burner cap includes a sheet metal base bounded by a peripheral lip and a sheet metal top extending over the sheet metal base to define a gap and having a peripheral rim that wraps about at least a portion of the peripheral lip. The sheet metal base defines at least one port configured to allow air to flow into and out of the gap.

A method and apparatus for a gas burner head with one or more rotating burners. The gas burner head may include an outer burner and an inner burner rotating about an axis. Multiple gas burner heads may be rotatably interconnected. Rotating one or more burners within one or more gas burner heads may allow a variety of burner characteristics and/or patterns. One or more gas burner heads may be used in a variety of applications.

A cooktop appliance includes a top panel. A gas burner assembly includes an annular burner body positioned on the top panel at a top surface of the top panel. The annular burner body defines a central combustion zone. The annular burner body also defines a plurality of flame ports at the central combustion zone. Gaseous fuel is flowable from a fuel chamber within the annular burner body into the central combustion zone through the plurality of flame ports. The gas burner assembly further includes features for direction the gaseous fuel into the fuel chamber of the annular burner body. The annular burner body is open at the central combustion zone such that the top panel is exposed through the annular burner body at the central combustion zone.

A gas burner for caravans, boats and vehicles in general includes an injector holder to be applied at an opening in a cooktop of a caravan, boat and/or vehicle in general and having an injector connected to a gas inlet; a burner cap resting on the injector holder and having a vertical conduit facing the injector at the bottom and leading, at the top, into a distribution chamber of the fuel mixture to generate a flame ring; and a cover resting on the burner cap and delimiting at the top the distribution chamber of the fuel mixture. At least two protruding pins are provided at the bottom surface of the cover and can be inserted into corresponding through holes in the burner cap to snappingly engage elastic coupling members coupled to the injector holder.
