    Abstract:

    The pellets induration process travelling in the strand of the furnace plays an important role on the final properties related to the mechanical strength and reducibility. The prediction of these properties taking into account the thermal history and the phase transformations is of special interest. In this study, a model based on the macroscopic and microscopic behavior of the individual pellets is proposed. The model is able to predict the thermal history of the bed and the individual pellets during the entire travelling distance within the furnace. The model is confronted with experimental results for individual pellets and the industrial data. Afterwards, the model is used to predict the effect of the increasingly use of biomass as solid fuel in the interior of the individual pellets and the furnace zones. Simulation results indicated that increasing the biomass solid fuel the carbon emission is reduced but with a decrease in the mechanical strength and increases on the reducibility.
