Abstract

Two topics are discussed in this chapter. The first is the particle-to-gas heat transfer inside particle arrays, i. e. in fluidized beds and in packed beds. Fine particles mean that particle-to-gas heat transfer is generally not a limiting factor, because heat exchange in the fluidized state is rather intensive, which produces temperature homogeneity throughout the bulk of the bed, even for strong exothermic reactions. However, supposed anomalies have been widely discussed in the literature and they need some clarification.
