A two-substance nozzle with a nozzle housing, the nozzle housing comprising at least one fluid inlet for fluid that is to be atomized, a second fluid inlet for gaseous fluid, a mixing chamber, a nozzle outlet opening and an annular gap opening surrounding the nozzle outlet opening, whereby, within the nozzle housing, means are provided for generating a film of fluid that is to be atomized on a wall in the mixing chamber, and inlet openings are provided for injecting gaseous fluid into the mixing chamber. The inlet openings and the mixing chamber are aligned and configured in a manner so as to inject the gaseous fluid essentially parallel to the wall in the mixing chamber and to move the stream of gaseous fluid within the mixing chamber essentially parallel past the wall.

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. 2. The two-substance nozzle as in claim 1, wherein the inlet openings for injecting gaseous fluid into the mixing chamber are aligned at an angle between 0 degrees and 30 degrees relative to the wall in a first third of a length of the mixing chamber. 3. The two-substance nozzle as in claim 1, wherein central axes of the inlet openings for the gaseous fluid are inclined relative to a central longitudinal axis of the mixing chamber in such a manner that the central axes of the inlet openings move toward the central longitudinal axis of the mixing chamber as viewed in a direction of flow of the gaseous fluid. 4. The two-substance nozzle as in claim 1, wherein the central pin is configured to divide the fluid to be atomized by means of flow energy of the fluid to be atomized into partial streams. 5. The two-substance nozzle as in claim 1, wherein the central pin is provided, in a region of a flow approach side for the fluid to be atomized, with at least two channels or furrows that extend from the tip of the central pin to a point of largest diameter of the central pin. 6. The two-substance nozzle as in claim 5, wherein the channels or furrows extend on generatrices of the central pin or are inclined with respect thereto. 7. The two-substance nozzle as in claim 1, wherein the central pin, when viewed in a direction of flow, has a tapering trailing body downstream of a region of maximum diameter. 8. The two-substance nozzle as in claim 1, wherein the central pin has the shape of a double cone. 9. The two-substance nozzle as in claim 7, wherein the wall in the mixing chamber is arranged so as to be substantially parallel to the tapering trailing body of the central pin. 10. The two-substance nozzle as in claim 7, wherein, viewed in the direction of flow, a free flow cross-section of the mixing chamber decreases in a course of the trailing body of the central pin. 11. The two-substance nozzle as in claim 7, wherein central axes of the inlet openings for the gaseous fluid into the mixing chamber are arranged so as to be substantially parallel to an outside wall of the trailing body of the central pin. 12. The two-substance nozzle as in claim 8, wherein a region with minimum cross-section of the mixing chamber is arranged on a level of a downstream tip of the double cone. 13. The two-substance nozzle as in claim 1, wherein the mixing chamber tapers in a form of a first hollow truncated cone and widens again, starting from a region of minimum cross-section in a form of a second hollow truncated cone, whereby central axes of the inlet openings for the gaseous fluid are aligned in the mixing chamber parallel to the wall of the mixing chamber in the second hollow truncated cone. 14. The two-substance nozzle as in claim 1, wherein the inlet openings for the fluid to be atomized are directed against a tip of the central pin, and the central pin is connected, via at least two radially extending strips, with the nozzle housing defining the wall of the mixing chamber. 15. A cluster nozzle for atomization of fluids including at least two two-substance nozzles as claimed in claim 1.
