ABSTRACT:
A nozzle for use in delivering a primary fluid having solids in solution or suspended therein which gives the fluid nozzle-caking tendencies. The nozzle has a first passage through which the primary fluid passes and a second passage through which a purging fluid passes, each passage terminating at an exit orifice. The orifice of the first passage is unrestricted and the orifice of the second passage has means for distributing the purging fluid in a manner to form a low velocity fluid buffer to inhibit caking of the solids of the nozzle due to reverse flow of the primary fluid caused by a circulating action thereof immediately after leaving the exit orifice of the first passage.
