Abstract

A two-fluid nozzle for atomizing an aqueous slurry includes a core member which will provide an atomized, cone-shaped spray of slurry droplets and an annular manifold which will provide a circular pattern of injected steam around the atomized slurry. The core member extends below the steam injection orifices and the bottom of the core is extended in diameter to form a concave groove and a lower lip which will disrupt the flow of steam from the injection orifices. A nozzle cap surrounds the slurry atomization and steam injection orifices.
