Sodium transformation simulation with a 2-D CFD model during circulating fluidized bed combustion

Investigation of the release behaviors of alkali and alkaline earth metals is necessary to understand the mechanisms of ash-related problems such as fouling, slagging, and corrosion when burning fuel with high alkali contents. Using a 2-D circulating fluidized bed (CFB) combustion model combined with a sodium migration model, sodium transformation was predicted in a 30 kW CFB combustor. Simulation results from the 2-D model are in agreement with...
