An atomizer nozzle for fuels, in particular for feeding them into a chemical reformer for obtaining hydrogen, has a nozzle body containing spray-discharge orifices that discharge into a metering space, and has at least one metering aperture. The spray-discharge orifices are situated at elevation levels so as to have a radial directional component with respect to a center line of the nozzle body, each elevation step having at least one spray-discharge orifice, and the spray-discharge orifices of at least one elevation level being connected to at least one channel of a nozzle-body insert that has at least one flow-through opening.
