Claims
- 1. A two-fluid nozzle for atomizing an aqueous slurry comprising:
- (a) a nozzle core with a conduit for the slurry which core terminates at its lower end with an aperture which will provide an atomized cone-shaped spray of finely-sized droplets of the slurry;
- (b) an annular manifold surrounding the nozzle core, said manifold adapted to provide a substantially circular pattern of an injected steam around the atomized slurry, said steam being injected through an annular orifice or a plurality of annularly-positioned, spaced-apart orifices;
- (c) wherein the nozzle core extends below the steam injection orifices by a distance of from about 1/4 to 3/8 inches, wherein the bottom portion of the core is extended in diameter to form a concave groove and a lower lip which will disrupt flow from the steam from the injection orifices;
- (d) a chamber which surrounds the slurry atomization and steam injection orifices, said chamber containing a vent aperture located below and spaced-apart from the atomization and injection apertures by a distance of from 1.6 to 3.2 inches.
- 2. The nozzle of claim 1 wherein the chamber is frustoconical in shape and terminates at a circular vent aperture.
- 3. The nozzle of claim 2 wherein the chamber is secured to the nozzle body by cylindrical threads.
- 4. The nozzle of claim 1 wherein the nozzle core contains a vertically-extending bore and a spinner and an orifice insert to atomize the slurry.
