FLUID INJECTION NOZZLE FOR FLUID BED REACTORS

A feed injector for a circulating fluid bed reactor is fitted with a discharge nozzle with a circular, radially notched discharge orifice to improve the surface-to-volume ratio of the spray pattern formed by the nozzle. The feed injector is useful for injecting fluids into various types of circulati...

Beschreibung
Zusammenfassung:	A feed injector for a circulating fluid bed reactor is fitted with a discharge nozzle with a circular, radially notched discharge orifice to improve the surface-to-volume ratio of the spray pattern formed by the nozzle. The feed injector is useful for injecting fluids into various types of circulating fluid bed reactors in which good contact between the components of the fluidized bed and the injected fluid is required. It is particularly useful in fluid coking reactors. L'invention concerne un injecteur d'alimentation pour un réacteur à lit fluidisé circulant, équipé d'une buse de décharge munie d'un orifice de décharge circulaire à encoche radiale permettant d'améliorer le rapport surface-volume du motif de pulvérisation formé par la buse. L'injecteur d'alimentation est utile pour injecter des fluides dans divers types de réacteurs à lit fluidisé circulant, dans lesquels un bon contact entre les composants du lit fluidisé et le fluide injecté est nécessaire. Il est particulièrement utile dans des réacteurs de cokéfaction fluide.
