The release of volatiles from the solid biomass is considered using devolatilization rates typically defined using the Arrhenius equation, which simply models the temperature dependence of the reaction rates. The simplest method for modelling the release of volatiles from a biomass fuel is to use a single rate for the volatiles as a whole. Several researchers have suggested a model framework that uses two or more rates to reflect the release of the different constituents of the biomass fuel (di Blasi, 2008). As for the gas phase reaction network, the consideration of several competing devolatilization rates is required for a more precise analysis. However, in practice the lack of precise data fo...
