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 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.

An oven appliance includes a cabinet defining a cooking chamber. The oven appliance further includes a gas burner assembly, the gas burner assembly including a burner tube disposed within the cooking chamber adjacent a top wall. The burner tube defines a passage extending from an inlet and further defines a plurality of outlet ports. The oven appliance further includes a conduit defined within the cabinet, the conduit defining a passage disposed exterior to the cooking chamber, the passage extending from an inlet. The conduit further defines a plurality of outlet apertures. The oven appliance further includes a duct defining a passage extending between an inlet and an outlet. The outlet is in fluid communication with the inlet of the burner tube for flowing primary air through the burner tube and in fluid communication with the inlet of the conduit for flowing secondary air through the conduit.

A cooktop grate assembly includes a heat shield having an outer rim and a central plateau region offset from the outer rim by a connecting wall. The central plateau region defines an opening for receiving a burner assembly. A grate is positioned over the heat shield. The grate includes supports that extend over the central plateau region. A gasket is disposed adjacent to the heat shield. The gasket engages at least one of a base of the grate and feet of the supports to retain the grate in position relative to the heat shield.
