摘要：

As an initial step for predicting the energy conversion effeciency of circulating fluidized bed (CFB) combustors and for future emission modeling, a model is presented which estimates the char holdup and the spatial distribution of the char particle size distribution inside a CFB combustion chamber. The submodel describing the combustion of a single particle is divided into three steps, namely, devolatilization, primary fragmentation and char combustion, which are treated independently.
