Abstract

An oxyburner (1) is associated with an opening (3) comprising a through passage (2) comprising a substantially cylindrical inlet region (5) receiving the downstream end of the oxyburner (1) and a substantially cylindrical outlet region (4) of a diameter D.sub.s and a length L.sub.s, the ratio D.sub.s /D.sub.e being comprised between 1.5 and 2.5 and the ratio L.sub.s /(D.sub.s -D.sub.e) comprised between 2 and 7. The speed of ejection of the oxygenated combustible gas is greater than 5 meters/second and the speed of ejection of the combustible gas is greater than the speed of the combustion-supporting gas.
