Hydrodynamics of a fluidized bed co-combustor for tobacco waste and coal

▸ A pioneering study of fluidization of binary mixtures containing tobacco stems. ▸ Three fluidization velocities are identified for different tobacco stem fractions. ▸ Four hydrodynamic stages are experienced with the increase of gas speed. ▸ High speed gas jet should be used to improve the mixing and fluidisation effect.
