A method and a device are described for injecting a fuel/liquid mixture into the combustion chamber of a burner, with an atomizer nozzle and with at least one liquid delivery region, at least one fuel delivery region separated from the latter and at least one volume region which is provided upstream of the atomizer nozzle orifice and in which the liquid is mixed with the fuel.The invention is distinguished in that the liquid experiences the generation of vortices before or during intermixing with the fuel.

1. An atomizer nozzle device for injecting a fuel/water mixture into a combustion chamber of a burner, comprising:at least one water delivery part and at least one fuel delivery part separated from the at least one water delivery part, and with at least one volume upstream of an atomizer nozzle orifice in which water can be mixed with fuel; and wherein the fuel delivery part is provided axially relative to the atomizer nozzle orifice, said fuel delivery part being surrounded coaxially by the water delivery part, and wherein there is provided between the two delivery parts an intermediate wall which has orifices through which the water in liquid state is introduced in the fuel delivery part perpendicularly to a flow of the fuel and enters the fuel delivery part swirled, and where the water is intermixed with the fuel before the fuel/water mixture flows out through the atomizer nozzle orifice; and wherein the orifices are positioned in the intermediate wall in such a way that a contour of orifices induce a water flow rotating around an axis of the atomizer nozzle orifice in the fuel delivery part.
