Heat transfer in circulating fluidized bed boilers

• Conditions of significance for heat transfer in circulating fluidized bed boilers, such as the shap of the heat receiving surfaces, particle concentrations, and some characteristics of the thermal boundary layers are described. Simplified boundary layer equations are formulated and are related to published work. It is stated that radiationand heat transport by particles across the boundary layer are the principal mechanisms of heat transfer in circulating fluidized bed boilers. On the basis of this general survey of the heat transfer situation, published work during the past few years is briefly reviewed.
