Cross Sectional Suspension Density along the Height of a CFB Riser under Fixed and Variable Bed Inventory Conditions
Experiments were performed in a cold model circulating fluidized bed riser having a cross sectional area of 100 x100 mm2 and a height of 4800 mm. Sand having an average diameter of 231m was used as the bed material. The cross sectional average suspension density along the height of the circulating fluidized bed system with a smooth exit was investigated under fixed and variable bed inventory conditions. A model is proposed for predicting the density profiles in the two conditions.
