A modeling approach to co-firing biomass/coal blends in pulverized coal utility boilers: Synergistic effects and emissions profiles

Pulverized coal power plants in Chile are evaluating to reduce CO2 emissions by co-firing coal with biomass, which is CO2-neutral. A computational fluid dynamics model was used in this study to predict the performance of a 150 MW commercial boiler co-firing pulverized coal with pine sawdust. Synergistic effects were identified by burnout, thermal and hydrodynamic profiles. Co-firing was simulated with 5% of biomass substitution, and feeding in...
