Packed Bed Combustion Modeling: A Proposed Methodology for Industrial Biomass Grate Burners

A. Rezeau, C. Bertrand, L.I. Díez & J. Royo
In this paper, a new approach for the combustion modelling of thick particles in a packed bed is presented. This research work is mainly devoted to an industrial application, so it requires an adequate balance between computational costs and accuracy. Consequently, the fuel bed is idealized as a porous medium with a constant volume and the different reactions that represent the particles combustion (drying, pyrolysis and char conversion) take place on its specific surface area....
