Abstract
The object of the invention is to provide a two-stage pressure atomizer nozzle for at least one liquid to be atomized, with which two-stage pressure atomizer nozzle improved liquid distribution in the exterior space of the pressure atomizer nozzle, in particular improved fuel distribution in a premix burner, can be achieved. To this end, the pressure atomizer nozzle has a nozzle head (4) connecting the outer and inner tubes (2, 3) to one another downstream. At least two separate turbulence and/or swirl chambers (9, 10, 11, 12) are arranged in the nozzle head (4). Each of these turbulence and/or swirl chambers (9, 10, 11, 12) is connected to the second feed passage (6) via at least one swirl passage (16), to the first feed passage (5) via at least one turbulence-generator passage (15) and to the exterior space (18) of the nozzle body (1) via a discharge opening (17).
