A gas burner arrangement for a household cooking appliance includes a hob plate and a gas burner mounted on the hob plate. The gas burner includes a first mixing chamber for mixing combustion gas with primary air, a second mixing chamber, separate from the first mixing chamber, for mixing combustion gas with primary air, at least one first primary air opening for supplying primary air to the first mixing chamber, and at least one second primary air opening for supplying primary air to the second mixing chamber. The at least one first primary air opening is arranged below the hob plate and the at least one second primary air opening is arranged above the hob plate.

A multi-crown gas burner with an injector holder module is attachable to a cooking hob and includes a flame-spreader module, positioned above the injector holder module, which includes a circular internal portion separated from an external annular portion by a substantially annular cavity. The injector holder module includes: at least one first venturi duct substantially horizontal to which at least one first injector faces, the at least one first venturi duct in fluid communication with a corresponding first chamber in fluid communication with a first set of doors provided in said external annular portion, so as to generate at least one first crown of main flames, a second substantially horizontal venturi duct to which a second injector, the second venturi duct is in fluid communication with a zone communicating fluidly with at least one passage provided in said circular internal portion for generating at least one simmering flame.

Provided is a flare tip. The flare tip, according to one embodiment, includes a flare tip enclosure. The flare tip, according to this embodiment, additionally includes two or more flare tip arms extending from the flare tip enclosure, wherein the two are more flare tip arms are largely equidistance from one another, and two or more flare tip orifices located in each of the two or more flare tip arms.

A gas burner for a cooking appliance includes a body defining perimeter and having a plurality of first groups of respective pluralities of first outlets a plurality of second groups of respective pluralities of second outlets. Each of the first outlets respectively defines a first outlet area, and each of the second outlets defines respective reduced outlet areas that are less than the first outlet area. Further, the first groups and second groups are alternately arranged around the perimeter, and a total number of first outlets is greater than a total number of second outlets.

A cover member of a gas supply manifold has a bent rising wall portion that is formed by bending a part of the cover member so as to rise in an opposite direction of a main body. The bent rising wall portion is in a form of a loop surrounding the entire circumference of a gas supply flow path and an area around the gas supply flow path. Such configuration increases the rigidity of the cover member and prevents large distortion of the cover member and leakage of gas from the gas supply flow path. As a result, the thickness of the cover member is reduced and the weight and the production cost of the gas supply manifold are also reduced.

A powered secondary air supply ranger burner and method thereof provide an efficient burner with improved heat transfer. An atmospheric range burner controls a burner flame by insulating the burner and supplying a secondary air to the burner. The secondary air concentrates a heating zone to a center of a cooking vessel to be heated by the burner flame. The secondary air also controls a size and a shape of the burner flame.
