Abstract

The invention relates in particular to a burner head (1) comprising a tubular end-piece (2), having an axis (4), which internally contains feed means (18, 26) for oxidant (23) and combustible (22, 22') fluids, and a deflector (36), the fluids flowing through the end-piece and beyond along a general flow direction (20). The head is characterised in that it furthermore includes at least one part (42) which aligns the flow of the fluids beyond the deflector, which has, along the flow direction, a first upstream portion of reduced radial section, oriented towards the deflector, then a second downstream portion, of larger section. The invention applies in particular to gas burners, for example with blown air.
