Inner swirling flame gas burner

A gas burner 10 having a combustion chamber 40 with a bottom 90 and a circumferential wall 92. A plurality of fuel exit ports 38 are disposed in the circumferential wall 92, and are directed generally inwardly toward the combustion chamber 40 and upwardly from the bottom 90 of the combustion chamber 40. The fuel exit ports 38 are preferably directed inwardly at an angle that is slightly rotated from a central axis 76 of the burner 10 to create a swirling flame. A plurality of secondary air inlets 44 extend through the bottom 90 of the combustion chamber 40. An injector orifice 16 is aligned with the central axis 76 of the burner 10. The injector orifice 16 is secured to the cooktop 12 using a bracket 22, which has an orifice-securing surface 60, with two sidewalls 64, 68 extending therefrom and terminating in fastening flanges 72. The fastening flanges 72 have asymmetrically arranged slots 82 therein to receive tabs 80 extending from the burner 10 to ensure proper alignment of the burner 10 and the injector orifice 16.
