Abstract

A pre-mixing gas burner apparatus comprises mixing means for mixing an air/gas mixture which is intended to be conveyed to the intake section of a fan unit (4), whose deliver)' is conveyed to a combustion head (2) of the burner, the mixing means comprising a plurality of ducts (12), each of which has a region in the form of a Venturi duct with contiguous portions (16a, 16b) which are convergent/divergent, with respect to the direction of flow, and with a restricted duct cross-section (16c) defined between the convergent portion and the divergent portion, there being conveyed in each convergent portion (16a) an air flow which is intended to be mixed with a gas flow which is introduced into the duct at the restricted cross-section (16c), the air/gas mixture being conveyed through the divergent portion (16b) of the duct to the intake section (10) of the fan unit (4). Each duct (12) of the plurality is defined by the engagement of at least a first and a second mutually separate burner region (A.B), along a mutual engagement profile, there being carried on each of the burner regions (A, D) corresponding, separate portions of each of the ducts (12), at least a first fluid-tight sealing element (20) being provided between the burner regions (A, B) along the engagement profile in order to prevent gas and/or air from being drawn in with respect to the ducts (12). The at least first sealing element (20) is interposed between the burner regions (A, B) at the restricted cross-section (16c) of each of the Venturi ducts of the plurality of ducts (12); the at least first sealing element
