Abstract:
1. A two-substance nozzle comprising a nozzle housing, said nozzle housing comprising at least a first fluid inlet for fluid to be atomized, a second fluid inlet for gaseous fluid, a mixing chamber, a nozzle outlet opening, an annular gap opening surrounding the nozzle outlet opening, means for generating a film of fluid to be atomized on a wall in the mixing chamber within the nozzle housing, and inlet openings injecting gaseous fluid into the mixing chamber, wherein the inlet openings and the mixing chamber are aligned and configured in a manner so as to inject the gaseous fluid substantially parallel to the wall in the mixing chamber and to move the gaseous fluid within the mixing chamber substantially parallel past the wall, wherein the means for generating a film of fluid to be atomized comprises droplet loading means in the mixing chamber for loading the gaseous fluid with fluid droplets at least in regions remote from the wall with the film of fluid, said regions not being decelerated by friction between the film of fluid and the gaseous fluid, and wherein the means for generating a film of fluid to be atomized comprise a central pin, whereby one of the inlet openings for the fluid to be atomized is directed at a tip of the central pin, and the central pin initially widens in a cone configuration starting at the tip.
