This work presents a model for prediction of the solids inventory in CFB boilers. The model has as input the operational strategy undertaken to control the solids inventory and accounts for the internal solids size segregation in the circulating loop and solids attrition. The model is transient in that it resolves changes in the size distribution of the bed inventory over time. Model results are compared to experimental data from the Chalmers 12 MWth CFB boiler, showing good agreement.
