Claim 8:
9. A burner comprising:
a body containing at least one injector;
a crown disposed on said body; and
a cap disposed on said crown, wherein said crown comprises:
a truncated conical lateral edge having a decreasing diameter extending, upwardly and an inclination of between 20° and 70° relative to a horizontal plane; and
a cylindrical seat that is open on a top thereof, wherein said cap is disposed in a cylindrical seat, said cylindrical seat having a cylindrical lateral wall, wherein said cap has a lateral edge that comprises:
a first truncated conical portion with a downward inclination of approximately 20° to 70° relative to the horizontal plane;
a cylindrical portion;
a lower horizontal surface; and
a plurality of apertures adapted to allow emission of flames from said first truncated conical portion of said cap, said plurality of apertures being through holes with an emission axis that is inclined upwards by approximately 20° to 70° relative to the horizontal plane, wherein said first cylindrical portion of said cap is disposed in a distal position relative to a position of the cylindrical lateral wall of said seat of said crown so as to define an annular gap, the annular gap adapted to allow an omission of a pilot flame, said cap having an upper surface with a circular planar horizontal shape that is recessed relative to a joining surface that joins the upper surface with the lateral edge, wherein the joining surface is inclined upwards relative to the upper surface by an mole of between 18° to 22° relative to the horizontal plane.
