![عکس صفحه اول مقاله: Identification of stable operating ranges of a counter-current multistage fluidized bed reactor with downcomer Identification of stable operating ranges of a counter-current multistage fluidized bed reactor with downcomer](/preview/png/687459.png)
This paper describes the stable operating range for a multistage gas–solid fluidized bed reactor and the influence of downcomer and aspect ratio on stable and uniform gas–solid fluidization. A three-stage counter-current fluidized bed reactor was designed, fabricated and operated and range of stable operation for lime and sand particles has been determined. In addition to that a comprehensive discussion on dynamics of downcomer has been made to ensure smooth transfer of solids from one stage to another. A theoretical model has been developed to predict the solid height in downcomer and tested for experimental conditions. The influence of aspect ratio on distributor to bed ratio (Pp/Pb) was investigated for the reactor for uniform fluidization.
