Abstract

1. A burner with vanes of the kind comprising an opening (3) in the wall (1) of a combustion chamber, a nozzle (4) for injection of a combustible substance through the opening and an assembly (5, 6) for distribution of secondary air of combustion comprising a plurality of deflecting vanes (5) disposed annularly around the nozzle so as to make the combustion air flow together with the combustible substance in a helical trajectory, the secondary air of combustion being injected transversely towards the vanes (5) from a plurality of at least two injectors (7) regularly distributed around the said nozzle, characterized in that to allow a supply of secondary air of combustion without an air box, the injectors and the vanes are disposed immediately behind the wall (1) of the combustion chamber (2) and in that the axial deviation of this secondary air of combustion (before its meeting with the combustible substance) is controlled by means of a circular flange (6) movable along the nozzle and presenting openings crossed by the vanes.
