Abstract

The gas burner has a central gas supply channel (3), two concentric annular air supply channels (4,5), and a burner nose (10). A first series of orifices (14) for gas passage are located in a ring in communication with the central channel. A second series of orifices (15) for passage of air are located in a ring around the gas orifices and are in communication with one (4) of the annular channels. A third series of orifices (18) for air passage are located in a ring and communicate with the second (5) of the annular channels. The first series of orifices are inclined relative to the axial direction (X) of the burner nose and diverge towards the outside of the burner. This creates a divergent gas flow. The second series of orifices are in a helix so as to create a turbulent air flow which intersects the gas flow.
