Abstract

Burner (1) supplied with a gas and air fuel mixture, comprising a diffuser on which openings (10) are made for the passage and subsequent combustion of said mixture, said diffuser being divided into a plurality of diffuser elements (3, 3a) that are adjacent to one another, each diffuser element (3, 3a) has a pair of converging slopes (8, 9; 8a, 9a) that converge together, said openings (10) being made in each of the slopes (8, 9; 8a, 9a) of said pair of slopes.
