Disclosed herein is a nozzle tip that atomizes a liquid entering a vessel or reaction zone that contains circulating fluidized particulates where the nozzle tip comprises a first elongated slot that intersects with a second elongated slot to define a single orifice. The first elongated slot may have members protruding into it and the slots may intersect substantially orthogonally and bisect each other. The length of the minor axis of the first slot ranges form about 5% to about 50% of the length of the major axis of the first slot and the length of the minor axis of the second slot ranges form about 1% to about 10 % or the major axis of the second slot. This nozzle tip affords erosion reduction caused by the circulating fluidized particulates and therefore provides longer operational lifetimes for the nozzle tip.
