Abstract

A Computational Particle Fluid Dynamic (CPFD) model has been developed for the heat transfer optimization in a fluidized bed biomass gasification reactor with gasification reaction kinetics. The parameters investigated were bed material circulation rate, bed material inlet and outlet temperature, steam feed temperature and fluidizing velocity of steam. A series of simulations were performed for each of the parameters. Commercial CPFD software Barracuda was used for the simulations. The result of the simulations are used to propose optimal parameters for heat supply in the gasification reactor. Keywords: heat transfer, fluidized bed reactors, CPFD, Eulerian-Lagrangian approach, reaction kinetics, biomass gasification.
