Abstract: The hydrodynamics behavior of a bench-scale circulating fluidized bed (CFB) system has been analyzed in terms of the axial pressure profile and solids circulation rate. Experimental runs were carried out at room conditions using beds of quartz sand and air as the fluid phase in order to know the effect of the overall solids inventory and the superficial gas velocity used in the riser. Static pressure signals obtained from the gasparticle flow were registered at several positions along the CFB loop and the solids circulation rate was measured by using a diverter valve installed at the standpipe section. A statistical analysis applied on the experimental data show that the solids inventory and the superficial gas velocity in the range here studied lead to significant changes on the hydrodynamics of the circulating fluidized bed system. Keywords: Circulating fluidized bed riser, gas-particle hydrodynamics, static pressure signals, solids circulation rate
