A flat-jet nozzle for atomizing liquids into comparatively large drops and comprising a nozzle housing with an axial feed passing through it with a multiple stepped diameter, this feed being provided at its end with a nozzle discharge slit. Moreover an inset with a central throttling bore is mounted in the liquid feed between the liquid intake and the discharge slit. A cylindrical central zone of a larger diameter than the discharge slit is present in the liquid feed in the nozzle housing. The inset is provided with a deflector through which the liquid jet issuing from the throttling bore into the central zone is forced, preferably bilaterally, toward the large axis of the nozzle discharge slit.

Flat-jet nozzle to atomize liquids into comparatively coarse drops

A cylindrical inset forming a mixing chamber in a binary atomizing nozzle is mounted in a housing ahead of the nozzle discharge and is provided with radial boreholes. The liquid to be atomized, for instance water, and the atomizing gas, for instance air, are fed to the cylindrical inset, with the liquid arriving axially and the gas passing radially from an annular spacing surrounding the inset within the nozzle housing through the radial boreholes into the inset. The radial boreholes are located in several consecutive transverse plans when viewed in the direction of flow and are arrayed in mutually offset manner in the circumferential direction of the cylindrical inset.
