Abstract
The invention relates to a hot-gas generating burner comprising a nozzle charging a fuel jet which then enters a mixing tube, and an orifice plate surrounding the outlet of the nozzle. The casing of the burner is divided by the orifice plate into an upstream-disposed precombustion chamber which includes the nozzle, and a downstream combustion chamber which contains the mixing tube. The orifice has a central passage for the fuel jet which is discharged from the nozzle and a number of openings surrounding the passage. In order to reduce the noise concomitant with the operation of the burner, the spacing between the peripheries of the neighboring openings equals at least 50% of the diameter of the openings, and/or the openings in the orifice plate are associated with at least one air duct in the direction of flow.
