Burner comprising: - a body suitable for containing at least one injector, - a crown disposed on the body, and - a cap disposed on the crown, said crown comprising: - a truncated conical lateral edge with decreasing diameter from down up and inclination comprised between 20°-70° relative to a horizontal plane, and - a cylindrical seat that is open on top, wherein the cap is disposed in such a way to define a distribution chamber of air-gas mixture between the crown and the cap; the cylindrical seat having a cylindrical lateral wall; said cap having a lateral edge that comprises: - a first truncated conical portion with downward inclination of 20°-70° relative to a horizontal plane, - a second cylindrical portion, - a lower horizontal surface with a step, and - a plurality of apertures for the flames obtained in the first truncated conical portion of the lateral edge of the cap; said apertures being through holes with an emission axis of the flames that is inclined upwards by approximately 20°-70° relative to a horizontal plane; wherein the second cylindrical portion of the lateral edge of the cap is disposed in distal position relative to the cylindrical lateral wall of the seat of the crown, in such a way to define an annular gap for the emission of a pilot flame, said crown comprising an annular collar that protrudes upwards and suitable for supporting said step of the cap; the annular collar having an upper edge with a plurality of cavities, wherein said cap is die-cast and the apertures of the cap have an axial length of approximately 5-6 mm, and said cavities of the annular collar of the crown have a radial horizontal axis and are arranged radially outwards with respect to an inlet of the apertures of the cap in such a way to feed air-gas mixture in said annular gap for the pilot flame. - a body suitable for containing at least one injector, - a crown disposed on the body, and - a cap disposed on the crown, - a truncated conical lateral edge with decreasing diameter from down up and inclination comprised between 20°-70° relative to a horizontal plane, and - a cylindrical seat that is open on top, wherein the cap is disposed in such a way to define a distribution chamber of air-gas mixture between the crown and the cap; the cylindrical seat having a cylindrical lateral wall; - a first truncated conical portion with downward inclination of 20°-70° relative to a horizontal plane, - a second cylindrical portion, - a lower horizontal surface with a step, and - a plurality of apertures for the flames obtained in the first truncated conical portion of the lateral edge of the cap; said apertures being through holes with an emission axis of the flames that is inclined upwards by approximately 20°-70° relative to a horizontal plane; wherein the second cylindrical portion of the lateral edge of the cap is disposed in distal position relative to the cylindrical lateral wall of the seat of the crown, in such a way to define an annular gap for the emission of a pilot flame, said crown comprising an annular collar that protrudes upwards and suitable for supporting said step of the cap; the annular collar having an upper edge with a plurality of cavities, wherein said cap is die-cast and the apertures of the cap have an axial length of approximately 5-6 mm, and said cavities of the annular collar of the crown have a radial horizontal axis and are arranged radially outwards with respect to an inlet of the apertures of the cap in such a way to feed air-gas mixture in said annular gap for the pilot flame.
