叙述了循环流化床锅炉传热的重要条件，如受热面形状、颗粒浓度和热边界层的一些特性。简化了边界层方程，并与已发表的工作有关。指出了边界层的辐射传热和颗粒传热是循环流化床锅炉传热的主要机理。在此基础上，简要回顾了近年来已发表的传热研究成果。
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.
