Abstract: What is described is a burner, specifically for gas fuels with premixing, comprising a burner body designed to be housed in a combustion chamber of a heating apparatus, the burner body being provided with a burner head on which an air and gas mixture supplied to the combustion chamber is burnt, in which the burner head has a surface profile in the form of a dome-shaped spherical segment, the height of the dome being less than half of the diameter of the sphere to which the segment belongs.

Abstract: A burner is provided and includes a cylindrical burner head housed in a combustion chamber of a heating apparatus, on which an air and gas mixture is burnt, the head including a cylindrical shell with through apertures, fixed at a first axial end by a connecting flange to a shutter element intended to seal the combustion chamber, while its opposite axial end has a solid end wall which seals the head, an element for distributing the air and gas mixture, positioned inside the burner head and intended to distribute the flow of combustible mixture reaching the burner on to the burner head. The distributor element includes a plate-like portion extending as a continuation of the connecting flange and extending substantially in an orthogonal direction to the axial direction of extension of the cylindrical head, the plate-like portion having through apertures for distributing the mixture to the burner head.
