Internally circulating fluidized beds (ICFBs) have been applied to a number of processes and provide a means of exchanging the bed particles from one reaction chamber to the other. Fundamental to this system is a good knowledge of the solids circulation rate (SRR). This paper summarises experimental investigations conducted using a hot tracer technique to measure the solids recirculation flux through an ICFB with a reaction and heat exchange chamber. Possible predictive models which link the bed hydrodynamics to the SRR are also evaluated.
