Abstract:
1. A burner comprising at least two supply channels for a separate supply of a liquid fuel and an oxygen-containing gas defined by at least two tubular walls extending in a coaxially spaced relation from a supply side to a discharge end, the burner comprising a twin-fluid atomizer head fixed to the discharge end comprising one or more first flow-through passages fluidly connected to the supply channel for oxygen containing gas and second flow-through passages fluidly connected to the supply channel for the liquid fuel, the second flow-through passages exiting into the one or more first flow-through passages under an angle at a point before the first flow-through passages exit into a coaxial ring of orifices, wherein a cooling jacket is coaxially disposed to envelope the tubular supply channel walls and wherein the orifices run through the atomizer head at a distance from the cooling jacket and wherein the atomizer head is made of a first metal and the cooling jacket is made of a second metal with a lower thermal conductivity than the first metal wherein the atomizer head comprises a threaded skirt provided with a screw thread functionally cooperative with a corresponding screw thread on the cooling jacket.
