A Study on Dioxin Reduction Characteristics of Rapid Cooling Type Circulating Fluidized Bed Heat Exchanger

급속냉각형 순환유동층 열교환기의 다이옥신 저감성능 연구

The flow and heat transfer performance were measured at high temperatures in CFB heat exchanger with multiple risers and downcomers. The theoretical model for predicting heat exchanger performance was developed in this study. The model predictions were compared with the measured heat transfer rates to show relatively good agreement. The maximum gas cooling rate was $20,300^{\circ}C/sec$, and the dioxin reduction rate was 68%.
