Co-Gasification Characteristics of Coal and Biomass Using CO<sub>2</sub> Reactant under Thermodynamic Equilibrium Modelling

This study assessed the entrained flow co-gasification characteristics of coal and biomass using thermodynamic equilibrium modelling. The model was validated against entrained flow gasifier data published in the literature. The gasification performance was evaluated under different operating conditi...
