Cross Sectional Suspension Density along the Height of a CFB Riser under Fixed and Variable Bed Inventory Conditions

Abstract:

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 231m 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.
