| Abstract: | Mathematical model is an important method in the study and the development of large-scale circulating fluidized bed(CFB) boiler.On the basis of the overall mathematical model for the medium and small scale CFB boiler,a mathematical model for large-scale CFB boiler is developed.In the modeling,the CFB riser is divided in two regions:the bottom zone in turbulent fluidization regime and the upper zone with core-annulus solids flow structure.The model takes into account the fragmentation and combustion process ... |
