A gas burner for a cooktop includes a spreader extending along a major axis to define an elongated shape. The spreader further defines an underside and includes a first projection and a second projection extending away from the underside. An orifice holder includes a body and a first lobe and a second lobe extending radially outward from the body. The first and second projections are opposingly adjacent to at least one of the first and second lobes. The orifice holder is mutually engageable with the spreader, with the first and second projections opposingly adjacent with at least one of the first and second lobes.

A radiant tube burner, wherein an opening cross section of the tube is virtually divided into four areas with two straight lines as boundaries, the two straight lines being obtained by tilting a minor axis of the oval, which is a shape of the opening cross section, by ±45° with a center of the oval as a center, and a flow rate of primary combustion air injected from primary combustion air nozzles located in the areas containing the minor axis of the oval of the virtually divided four areas is lower than a flow rate of the primary combustion air injected from the primary combustion air nozzles located in the areas not containing the minor axis of the oval the four areas.

A cooking burner includes a spreader defining a first side wall defining an outer profile having first and second extension sections opposed about a first axis. The spreader further defines first and second arced sections, each extending outwardly along a second axis perpendicular to the first axis from and between parallel straight segments of the first and second extension sections, respectively. The spreader further defines a second side wall disposed inwardly of and concentric with the first and second arced sections and a plurality of fuel outlets extending through both the first side wall and the second side wall. A circular inner cap is assembled with an upper portion of the circular inner profile, an annular outer cap is assembled with respective upper portions of the first and second arced sections, and first and second extension caps assembled with respective upper portions of the first and second extension sections.

A burner for use with an igniter for firing a flame into a heat-exchanger includes a body having a sidewall that defines an interior chamber. A first opening in the body receives a pre-mixed mixture of air and fuel. A second opening in the body is in fluid communication with the first opening. A distributor is connected to the body and closes the second opening. The distributor includes a first portion and at least one curved second portion provided on the first portion. Each second portion includes a plurality of first perforations in fluid communication with the first opening in the body. The first perforations of one second portion are positioned adjacent to the igniter such that ignition of the pre-mix mixture flowing through the first perforations results in a flame through the second portion. A flange extends around the first portion and includes second perforations.

A home cooking appliance includes a cooktop surface and a gas pedestal burner on the cooktop surface. The gas pedestal burner includes a burner portion having a sidewall, a lower surface facing the cooktop surface, a plurality of burner ports in the sidewall, and a base portion under the burner portion. The base portion elevates the burner portion in a vertical direction above the cooktop surface and has a lower mounting surface disposed on the cooktop surface. An area of a footprint of the lower mounting surface of the base portion is less than an area of a footprint of the lower surface of the burner portion.

A cooking appliance is provided, including a multi-level gas burner with a body having a lower burner section on a lower side and an upper burner section on an upper side. The lower burner section is separated from the upper burner section. The lower side of the body has a first injection point for receiving a first air-gas mixture for the lower burner section and a second injection point for receiving a second air-gas mixture for the upper burner section. The first injection point is partitioned from the second injection point thereby separating the first air-gas mixture from the second air-gas mixture. The body includes a passageway fluidly connecting the second injection point on the lower side of the body to the upper burner section on the upper side of the body.

A cooking appliance is provided, including a cooktop floor and a removable cooking vessel support system on the cooktop floor. The cooking vessel support system includes a support frame configured to support a cooking vessel above a gas burner, the support frame having at least a first arm supporting the gas burner above and spaced apart from the cooktop floor. The support frame includes an internal passageway in fluid communication with the gas burner and configured to draw primary air into the support frame at a location above the cooktop floor and to mix the primary air with an injected gas to provide an air-gas mixture. At least a portion of the internal passageway is formed in the first arm of the support frame such that the air-gas mixture is guided by the internal passageway through the first arm to the gas burner.
