In a spray nozzle, a carrier defines a spray aperture, a groove surrounding the spray aperture for receiving an o-ring, a first locating bore for slidably receiving an orifice plate seated against the o-ring and for aligning the orifice plate with the spray aperture, and a second locating bore for slidably receiving a swirl unit and aligning the swirl unit with the orifice plate and spray aperture. A pair of retaining lugs project inwardly from the carrier a predetermined distance for engaging the upstream end of the swirl unit to thereby retain the swirl unit and orifice plate within the carrier. The swirl unit defines on its peripheral surface a recessed flat which is aligned with the retaining lugs to thereby clear the lugs upon inserting the swirl unit into the carrier. An elongated slot is formed on the upstream end of the swirl unit for receiving a screw driver.

In a spray nozzle (10), a carrier (12) defines a spray aperture (20), a groove (30) surrounding the spray aperture for receiving an o-ring (32), a first locating bore (26) for slidably receiving an orifice plate (14) seated against the o-ring (32) and for aligning the orifice plate with the spray aperture, and a second locating bore (28) for slidably receiving a swirl unit and aligning the swirl unit (16) with the orifice plate and spray aperture. The swirl unit (16) defines on its peripheral surface a recessed flat (58) forming a fluid passageway between the swirl unit and carrier. The swirl unit (16) includes a swirl chamber (60) defined by a curvilinear surface (62) formed within the swirl unit, and an inlet port (64) formed in fluid communication between the swirl chamber and fluid passageway. The nozzle body (18) is threadedly received within the carrier (12) behind the swirl unit (16) to axially press the swirl unit, and in turn press the orifice plate (14) against the adjacent surface of the carrier.

A spray nozzle includes a body defining an inlet chamber and an outlet. An orifice disk, adjacent the outlet, has opposing surfaces, an inner sidewall extending between the opposing surfaces which defines an orifice, and a peripheral sidewall extending between the opposing surfaces for centering the orifice disk within the inlet chamber. A swirl disk, adjacent to the orifice disk, has opposing surfaces and a sidewall extending between the opposing surfaces. The sidewall of the swirl disk forms a periphery for centering the swirl disk, a hollow for creating a vortex adjacent to the orifice and an inlet for channeling fluid from the periphery to the hollow. A plug is fixed within the inlet chamber of the body for retaining the orifice and swirl disks as well as defining an annulus area in fluid communication with the inlet of the swirl disk.

A nozzle for discharging first and second fluids in a spray pattern into a vessel, such as oil and steam in a catalytic cracking unit, includes various configurations for preventing erosion of the outlet portion of the nozzle that otherwise might be due, for example, to contact with a catalyst or other predetermined substance. In one such nozzle, the exterior surface of the outlet portion substantially conforms to the internal contour of the vessel. In another such nozzle, the outlet portion defines a plurality of substantially concentric, substantially elliptical-shaped outlet apertures. In another nozzle, the outlet portion is formed of ceramic and is connected to the inlet portion by a metal connector. In another nozzle, the outlet portion defines a plurality of apertures angularly spaced about a peripheral region of the outlet portion for discharging a substantially flat fan spray pattern, and a second outlet portion extending along an upstream portion of the outlet portion for discharging at least part of its spray to prevent any catalyst from contacting the downstream surfaces of the outlet portion.

A spray nozzle for discharging at least one fluid in a spray pattern into a fluid stream in a vessel, such as an atomized mixture of oil and steam in a fluidic catalytic cracking unit, wherein the nozzle alters the flow patterns of the fluid stream in the vicinity of the nozzle to inhibit erosion of the nozzle and maintain the spray pattern. The nozzle comprises an inlet member defining at least one inlet conduit and an outlet member in fluid communication with the inlet member. The outlet member includes an exterior surface and a plurality of bosses angularly spaced relative to each other about an axis of the outlet, each boss defining an outlet aperture in fluid communication with the at least one inlet conduit having a length (L) and a diameter (D) and an axially extending wall, wherein the axially extending wall extends outwardly a length (X) greater than about ⅛ inch relative to the exterior surface and L/D is at least about ½.
