Abstract: Herein a gas boiler burner (1) is described comprising a diffuser, suitable for diffusing premixed fuel gases in a combustion chamber, in which the diffuser comprises a diffuser central portion (10) and two diffuser longitudinally peripheral portions (5), the two diffuser longitudinally peripheral portions (5) being connected together through the- central diffuser portion (10), the central diffuser portion (10) extending longitudinally in a direction perpendicular to the flow of the fuel gases over a length l greater than zero and having transversal cross- sections shaped as a circumference arc having a uniform radius of curvature r, each of the diffuser longitudinally peripheral portions (5) being shaped as a portion of a sphere having radius r.

Abstract: A temperature sensor for a burner comprises two metal wires implementing a thermocouple, a protection sheath receiving the two metal wires, and a head in metal material having a front side intended to be facing the environment, the temperature of which is intended to be measured, and a rear side opposite the front side, in which the two metal wires are connected in a thermal exchange relationship to the head rear side, and the head comprises a front portion connectable to a burner wall of the burner so that the thermocouple is connectable to the burner by means of said metal head.

Abstract: A burner suppliable with a mixture of air and fuel comprises a body of the burner provided with a diffuser in the surface of which openings are made for the exit of said mixture delivered into the body of the burner, and a distributing device inserted inside said body of the burner. The distributing device comprises a regulating element provided with further openings for the transit of the mixture, the regulating element being movable within the body of the burner. The body of the burner can be subdivided into a plurality of sectors, each one of which is independently suppliable by the other sectors.

Abstract: A burner suppliable with a mixture of air and fuel, comprising a diffuser on which holes are made for the passage and subsequent combustion of said mixture, said diffuser being divided into a plurality of diffuser elements adjacent to one another, said diffuser elements are fixable to a support and distribution element provided with first coupling elements for coupling with said diffuser elements and with openings for distributing said mixture to said diffuser elements.
