Abstract A simulation model of continuous lignite char combustion in a spouted bed has been developed to predict bed oxygen concentrations, bed particle size distribution, bed carbon loading, mean diameter of bed char, and the fractional combustion in spout, annulus, and fountain. The approach involves taking into account the spouted bed hydrodynamics, a burning law for individual particles, and the combines mass balances for bed char and oxidant in the three typical regions. The predicted results for various operating conditions are compared with some experimental data.
