A burner comprises a central passageway and outlets for fuel and for stabilizing oxidant arranged peripherally around the central passageway, and comprises outlets within the burner through which biasing gas, such as gas comprising oxygen, can be injected to enable control of the direction of the flame that is generated by combustion of the fuel and the oxidant at the face of the burner.

Burner Tubes for Gas Grills are disclosed. An example burner tube includes a linear burner tube including a venturi member disposed within a hollow interior of the linear burner tube proximate an open front end of the linear burner tube. The venturi member includes a front face having an opening configured to receive a neck of a gas valve, an upper flange extending rearwardly from an upper edge of the front face, the upper flange having a downwardly-extending V-shaped segment configured to constrict a region of the hollow interior, and a lower flange extending rearwardly from a lower edge of the front face, the lower flange having an upwardly-extending V-shaped segment configured to further constrict the region of the hollow interior.

A gas burner assembly for a cooktop appliance includes a flame ring comprising a plurality of flame ports arranged in an annular array. An outer ring and an inner ring collectively define each flame port of the plurality of flame ports. The outer ring and the inner ring are concentrically aligned and concentrically mated. As a result of this arrangement of the outer ring and the inner ring, the plurality of flame ports are defined by the outer ring and the inner ring. The plurality of flame ports extend radially between the inner ring and the outer ring.
