A burner comprising channels for the separate supply of a liquid fuel and an oxygen-containing gas. The burner comprises a twin-fluid atomizer head comprising first flow-through passages fluidly connected to the supply channel for oxygen-containing gas and second flow-through passages fluidly connected to the fuel supply channel. The second flow-through passages exit into the first flow-through passages at a point before the first flow-through passages exit into a coaxial ring of orifices. A cooling jacket envelopes the supply channel walls. The orifices run through the atomizer head at a distance from the cooling jacket. The atomizer head can, for example, be made of a first metal, such as a copper alloy, and the cooling jacket can be made of a second metal with a lower thermal conductivity than the first metal, for example steel. |
