A nozzle for controlling the spray pattern and the distribution of particles into a combustion chamber. The nozzle comprises a receiver in communication with a vortex chamber, which in turn is in communication with a discharge hood. The vortex chamber and the discharge hood are designed to reduce the air pressure within the nozzle, and to thereby decrease the velocity at which particles move through the nozzle. The nozzle further comprises a plurality of blades disposed on the vortex chamber which serve to control the spray pattern of the particles. The nozzle further optionally comprises a plurality of deflectors located on the discharge hood which further controls the spray pattern of the particles.
