In this paper, a model on attrition of quartzite particles as an inert bed material in fluidized beds has been established on the particle-particle collision. For the convenience of describing the attrition of quartzite particles in fluidized beds, we chose the attrition rate constant (k ARC ) as on
The elutriation rates of unburned carbon from a 20-cm-i.d. bubbling fluidized bed were evaluated for a variety of coals. Elutriation rates were determined from cyclone catches while carbon loadings in the fluidized bed were evaluated from transient gas and particle emissions. The elutriation rates w
