Abstract
A two-medium spraying nozzle is provided with a mixing chamber arranged in a housing and with one connection duct respectively leading into this mixing chamber for the feeding of a gaseous and of a liquid medium. A mouthpiece is connected behind the mixing chamber, in which mouthpiece a rotationally symmetrical central outlet opening is provided. In the bore of the mouthpiece, a swirl insert is arranged, and the outlet opening has a diameter which corresponds to no more than half the diameter of the bore of the mouthpiece. Such a two-medium spraying nozzle is unsusceptible to clogging and is particularly suitable for atomizing low-viscosity fluids for the cooling of continuous-casting systems for the production of steel.
