The outlet apertures, arranged in parallel planes in the burner surface of the gas burner, are brought together in groups with narrow parallel spacing. The spacing is so dimensioned in its width that diverging flames are formed. The outlet apertures (12) lying in a plane extend at least approximately over the complete effective burner surface, being distributed over it with equally narrow spacing. The pref. blower-supported feed pressure of the homogeneously pre-mixed combustion components and the resulting outlet speed of the fuel-air mixture are so increasable that fanned out and stabilised flame fronts (30,32) are produced, which locate on the gas burner only with their flame foot lines. |
