Abstract
A burner for combustible fluids has a distribution opening adapted to feed a combustion chamber and supplied by a source of a comburant (combustion-sustaining gas such as air or a mixture of air and combustion products), a swirl generator between this source and the opening, an injection nozzle for the combustible fluid extending coaxially through this opening, and a constriction located immediately ahead of the discharge end of the nozzle and adjacent an outwardly diverging passage adapted to generate a toroidal vortex in the region of the end of the nozzle.
