Cluster characteristics of Geldart group B particles in a pilot-scale CFB riser. II. Polydisperse systems

► Experimental cluster behavior of three polydisperse materials throughout riser. ► Two binary mixtures and one continuous particle size distribution (PSD). ► Similar to monodisperse results, riser local position is the key influence. ► Difference in cluster frequency and duration values between the two binary mixtures. ► Effect of operating condition apparent for continuous PSD.
