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

다관형 순환유동층 열교환기의 유동 및 전열성능 예측모델 연구

The pressure drop and heat transfer coefficient were measured at room temperature in CFB heat exchanger with multiple vertical tubes. Also the circulation rate of solid particles was measured. The theoretical model for predicting heat transfer coefficient using the solid flowrate was developed in this study. The model predictions were compared with the measured heat transfer coefficient to show relatively good agreement.
