A Study on Prediction Model of Heat Transfer Coefficient in the Circulating Fluidized Bed Heat Exchanger with Multiple Vertical Tubes

The pressure distribution and heat transfer coefficient were measured at room temperature in the high suspension density CFB heat exchanger with multiple vertical tubes and the effective density of CFB was determined. The theoretical model for predicting heat transfer coefficient was developed in this study. The model predictions were compared with the measured heat transfer coefficient to show relatively good agreement between them.
