Effects of biomass particle size during cofiring under air-fired and oxyfuel conditions

Holtmeyer, Melissa L.; Kumfer, Benjamin M.; Axelbaum, … - In: Applied Energy 93 (2012) C, pp. 606-613

Carbon capture and storage (CCS), when applied to biomass cofiring systems, can remove atmospheric CO2 since the CO2 that is consumed by the biomass during growth is not released back into the atmosphere. Biomass cofiring can also potentially contribute to meeting renewable portfolio standards...
