A coal combustion model for circulating fluidized bed boilers
Jan 01, 2000 · 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 …

Due to the bed material inside the boiler, fluidized-bed boilers have high heat transfer coefficients, utilize the entire boiler volume, have a uniform temperature distribution and have a low stable combustion temperature. Fluidized beds are capable of burning very wet fuels and fuel particles of sizes up to 80 mm (van Loo and Koppejan, 2006). Thus very little pre-treatment of the fuel is necessary.
