Burner (1) comprising channels (2, 3) for the separate supply of a liquid fuel and an oxygen-containing gas. The burner (1) comprises a twin-fluid atomizer head (4) comprising first flow-through passages (37) in register with the supply channel (3) for oxygen- containing gas and second flow-through passages (34) in register with the fuel supply channel (2). The second flow-through passages (34) exit into the first flow- through passage (37) at a point before the first flow- through passage exits into a coaxial ring of orifices (38). A cooling jacket (11) envelopes the supply channel walls (9, 10). The orifices (38) run through the atomizer head (4) at a distance from the cooling jacket (11). The atomizer head (4) can, e.g., be made of a first metal, such as a copper alloy, and the cooling jacket (11) can be made of a second metal with a lower thermal conductivity than the first metal, e.g., steel. |
