A cooktop appliance may include a top panel and a gas burner. The top panel may define an opening. The gas burner may include a burner body, a fuel tube, an injet bracket, and an insulator pad. The burner body may be positioned on the top panel at the opening. The fuel tube may extend below the burner body in upstream fluid communication therewith. The injet bracket may be mounted below the burner body. The injet bracket may define a fuel orifice disposed upstream from the fuel tube and below the top panel. The insulator pad may be disposed between the burner body and the injet bracket to restrict heat transfer therebetween.

A gas burner of a cooktop appliance includes an annular burner body extending along the circumferential direction with an annular fuel plenum defined within the annular burner body. A plurality of ports are defined in the annular burner body. Each port of the plurality of ports extends from the annular fuel plenum inward towards a center of the gas burner assembly. The gas burner assembly also includes a vortex shield inward of the annular burner body along the radial direction. The vortex shield is positioned and configured to redirect a flow of unignited fuel from the ports away from the center of the gas burner assembly.

A domestic gas burner comprising a housing with a chamber, which can be coupled to an optionally controlled feed for a gaseous fuel and is in open communication with the environment via flame ports for the purpose of igniting a gas flame. An inlet device is coupled to the housing and comprises an entrance for receiving gaseous fuel, ambient air, and an outlet for feeding a fuel/air mixture to the burner chamber. The entrance and the outlet are in open communication with each other via a fuel channel which extends therebetween and is bounded by a wall. A gas port debouches into the entrance during operation to feed a fuel flow. The entrance allows substantially free entry of ambient air, and the inlet device comprises auxiliary gas means for generating and maintaining a flow of an auxiliary gas, directed toward the outlet, over the wall of the fuel channel.

A gas burner device includes a burner; an injector configured to supply gas to the burner to generate a flame, the injector being on one side of the burner, the flame being generated around the burner as the gas supplied by the injector burns. The flame includes: a first flame portion farthest from an installation surface on which the gas burner device is installed, a second flame portion, and a third flame portion closest to the installation surface so that the second flame portion is between the first flame portion and the third flame portion and the second flame portion transitions the first flame portion into the third flame portion.

A high output gas burner such as for a food cooking appliance is disclosed. The gas burner is adapted to combust a mixture of gas and air. The gas burner has a cross ring having a plurality of radially spaced channels and a plurality of axially spaced channels. The radially spaced channels and the axially spaced channels are adapted to guide the air to be combusted with the gas. The radially spaced channels have a diameter of the order of 10 mm and the axially spaced channels have a diameter of the order of 8 mm.

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.
