摘要: Based on the analysis of flow characteristics of the FCC riser feedstock injection zone,
two novel feedstock injection structures are put forward. By investigating three flow
parameters in the feedstock injection zone under the three different structures (the
traditional and the novel No. 1, No. 2 structures): the local density, the particle
backmixng ratio, and the jet eigen-concentration, the flow feature under three structures
were obtained. The experimental results demonstrate that the flow features under both
proposed structures are obviously improved comparing with those under the traditional
structure. Especially, the performance of the deflector-structured No. 2is more desirable
than that of No. 1.
