CFD Simulation of a Fixed Bed 60 kW Biomass Boiler

R. Comesaña, J. Collazo, J.L. Míguez & J. Porteiro
The simulation of a biomass combustion system includes many sub-models to account the different processes that are taking place, such as fluid dynamics, homogeneous reactions, pollutant formation, heat transfer and biomass drying, devolatilization, and char oxidation. This work is focused on the simulation and the analysis of a commercial 60 kW biomass boiler with special focus on the treatment of the bed, species mixing and reaction, temperatures in the combustion chamber and heat exchange processes....
