利用已建立的数学模型，对循环流化床床层与壁面间的传热特性进行了预测．分析了床层密度、床层温度、流化速度、颗粒粒径以及壁面长度等设计和运行参数对传热系数的影响．结果表明，床层密度越大或温度越高，传热系数越大；而颗粒粒径越大或壁面长度越大，传热系数越小；流化速度对传热系数则影响不大． The established mathematical model was used to predict the heat transfer between the bed and the wall of the circulating fluidized bed. The effects of design and operating parameters such as bed density, bed temperature, fluidization velocity, particle size and wall length on the heat transfer coefficient were analyzed. The results show that the larger the bed density or the higher the temperature, the larger the heat transfer coefficient. The larger the particle size or the larger the wall length, the smaller the heat transfer coefficient, while the fluidized velocity has little effect on the heat transfer coefficient.
