Abstract:
1. A gas burner comprising: a) an annular body with a first gas inlet and a second gas inlet adapted to receive gas which entrains air within said body to form an air/gas mixture, b) an ignition plug extending upwardly from said body, c) an upwardly opening base seated on said body, the upwardly opening base having a central annular base wall forming an inner annular base channel and a concentric outer annular base channel, d) a flame divider including an annular flange that extends into said base, e) said flange having a circumferential outer wall and a circumferential inner wall, f) first and second annular chambers defined between said flame divider and said base, the first annular chamber formed between the central annular base wall and communicating with the outer annular base channel and the second annular chamber formed between the central annular base wall and communcating with the inner annular base channel, g) a first series of outwardly directed main ports defined at the upper edge of said outer wall of said flame divider, h) a second series of inwardly directed main ports defined at the upper edge of said inner wall of said flame divider, i) one of said annular chambers supplying the air/gas mixture to said main ports in said flame divider to create an outwardly directed main flame ring and an inwardly directed main flame ring, and j) radial apertures defined in the lower edge of said flame divider to allow flow of the air/gas mixture from said first annular chamber to said second annular chamber to form a minimum power flame ring on the exterior of said gas burner to stabilize said inwardly directed main flame ring.
