Embodiment Construction

[0024] refer to figure 1 - Figure 6, the gas boiler burner is indicated in its entirety by reference numeral 1 .

[0025] In particular, reference numeral 1 denotes a burner that generates heat by combustion of a premixed fuel gas, which typically includes fuel gas and air. Preferably, such fuel gas is fully premixed, ie no other components are added to the mixture fed to the burner.

[0026] The burner 1 comprises a combustion chamber 3 (in figure 1 Diffuser 2 in which the fuel gas diffuses in dashed lines).

[0027] The burner 1 is mounted on the frame 9 . The frame can be connected to the combustion chamber 3 by connecting parts.

[0028] The frame 9 also defines openings for the passage of the fuel and air mixture.

[0029] The diffuser 2 comprises a wall provided with a plurality of openings, the inner surface of which is fluidly connected to the gas supply pipe. Combustion occurs on the outer surface of this wall.

[0030] The diffuser 2 may comprise a distributor...

Abstract

A gas boiler burner (1) is described here comprising a diffuser adapted to diffuse premixed gas in a combustion chamber, wherein said diffuser comprises a diffuser central part (10) and two diffuser longitudinal peripheries part (5), said two diffuser longitudinal peripheral parts (5) are connected together by said central diffuser part (10), said diffuser central part (10) is longitudinally along the direction perpendicular to the flow of fuel gas Extending through a length l greater than zero and having a transverse cross-section shaped as a circumferential arc with a radius of curvature r, each of said diffuser longitudinal peripheral portions (5) is shaped as part of a sphere with a radius r.

Description

technical field [0001] The present invention relates to a high peripheral stability burner for a gas boiler. Background technique [0002] A prior art gas boiler comprises: a duct for feeding the burner with a premixed gas-air mixture; a burner generating heat by the combustion of said mixture in a combustion chamber; and possibly, connectable to a heat exchanger and / or supply ducts to ensure the closure of the combustion chamber and / or support elements for positioning the burner relative to this combustion chamber. [0003] The burner includes a diffuser through which premixed fuel and air gases are delivered to determine a flame pattern for heat generation. Typically, the diffuser comprises a wall provided with a plurality of openings, having an inner surface and an outer surface, the inner surface being fluidly connected to the supply pipe and thus in contact with the unburned mixture on which the combustion takes place. [0004] Upstream of the diffuser (with reference...
