主　　题：Mass and energy balance circulating fluidized bed–bubbling fluidized bed Dual-reactor Comprehensive model 

摘      要：An analysis approach considering gas-solids hydrodynamics,reaction kinetics and reacting species nonuniformity together in a dual-reactor system is presented for better understanding its mass and energy *** was achieved by a 3-dimensional comprehensive hydrodynamics and reaction model for the dual-reactor system,which was developed from the successfully verified 3-dimensional comprehensive combustion model for one circulating fluidized bed(CFB)system(Xu and Cheng,2019).The developed model and analysis approach was successfully used on a 1 MW circulating fluidized bed–bubbling fluidized bed(CFB-BFB)dual-reactor *** showed the sensible and chemical energy between two reactors as well as the energy distributions in each reactor were balanced and they agreed well with the experimental *** analysis approach indicated energy balance had a close relationship with the mass transfer in the CFB-BFB dual-reactor *** may be applied in a design and operation optimization for a dual-reactor system.
