A coal combustion model for circulating fluidized be

A steady state model of a coal-fired circulating fluidized-bed boiler, based on hydrodynamics, heat transfer and combustion, is presented. This model predicts the flue gas temperature, the chemical gas species (O 2, H 2 O, CO, CO 2 and SO 2) and char concentration distributions in both the axial and radial locations along the furnace including the bottom and upper portion.
