Co-Gasification Characteristics of Coal and Biomass Using CO2 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 gasifier data published in literature. gasification performance evaluated under different operating conditions, such as equivalence ratio, temperature, pressure to ratio. It is observed that lower heating value (LHV) cold gas efficiency (CGE) increase with increasing temperature until process reaches a steady state. effect on syngas composition dominant only at non-steady state conditions (<1100 °C). variation minor up blending 50% (PB50). However, PB50 shows higher LHV CGE than pure by 12%and 18%, respectively. Overall, favours an 12 MJ/kg 78%.
