摘要： 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 1/8 inch relative to the exterior surface and L/D is at least about 1/2.
摘要翻译：一种用于将喷雾图案中的至少一种流体排放到流体催化裂化装置中的诸如油和蒸汽的雾化混合物的容器中的流体流的喷嘴，其中所述喷嘴改变流体流中的流动模式喷嘴附近以抑制喷嘴的侵蚀并保持喷射模式。喷嘴包括限定至少一个入口管道和与入口构件流体连通的出口构件的入口构件。出口构件包括外表面和围绕出口的轴线相对于彼此成角度地间隔开的多个凸起，每个凸台限定与至少一个入口导管流体连通的出口孔，所述入口导管具有长度（L）和直径（D）和轴向延伸的壁，其中轴向延伸的壁相对于外表面向外延伸大于约1/8英寸的长度（X），并且L / D至少约1/2。
