<p>A gas burner (1) whose combustion head (5) contains a conical outflow nozzle (16) of the combustibile mixture formed by a hollow member having an at least in part conical outer surface (18), convering towards the flame outlet (15) of the combustion head (5) and provided with a circumferential series of axial grooves defining outflow channels (21) progressively tapering towards the flame outlet (15). These channels (21) communicate with respective oblique passages (22) opening into a crown of front holes (23), arranged coaxially with the cavity of the outflow nozzle (16). The gas burner (1) further contains a peculiar mixer member (11) for mixing the combustibile gas and air. <IMAGE></p> |
