The present invention provides a nozzle, nozzle assembly, and method of use thereof for atomizing a liquid stream into a flat fan-shaped spray. The nozzle and nozzle assembly are particularly useful for atomizing a hydrocarbon feed into a catalytic cracking zone of a fluid catalytic cracking (FCC) process. The nozzle includes a nozzle tip that has at least three substantially vertical openings extending from the inner surface of the nozzle tip to the outer surface of the nozzle tip. The openings are angled from 0 degrees to about 75 degrees. The present invention also provides a nozzle assembly containing at least three nozzles of the present invention that are radially mounted around the perimeter of an area to be sprayed.
