摘要：
A general mathematical model of circulating fluidized bed combustion (CFBC) is set up, in which it is emphasized to take the wide size distribution of bed inventory into consideration. Some aspects such as hydrodynamics, devolatilization of coal, combustion of char and the formation and reduction of harmful substances are considered in detail in order to describe the process precisely. By using the model, simulation is carried out with a Chinese CFBC boiler with a steam generating capacity of 35 t/h. Finally, simulation is carried out to predict the performance of the 50 MW Tsinghua CFBC boiler under design.
