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 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. 种用于循环流化床反应器的进料喷射器配备有排出喷嘴，该排出喷嘴具有圆形的、带径向凹槽的排出孔口以改善由喷嘴形成的喷雾图案的表面与体积比。进料喷射器对于将流体注射到不同类型的循环流化床反应器中是有用的，在所述循环流化床反应器中，需要流化床的成分与注入的流体之间的良好接触。它在流化焦化反应器中尤其有用。
