SEGREGATION OF PARTICLES IN BINARY SOLIDS CIRCULATING FLUIDIZED-BEDS

The segregation pattern of particles in circulating fluidized beds, 0. 097 m and 0.150 m in diameter and 3 m in height, was investigated by u sing two groups binary solid particles that are different in diameter and density. The influence of operating conditions on the extent of pa rticle segregation were examined. An empirical correlation for describ ing the extent of segregation was proposed. For distinguishing the seg regation/mixing flow pattern, a theoretical criterion was derived and a segregation diagram was then prepared.
