| #552 - Oxycombustion of Coal – Needs, Opportunities, and Challenges (07J01) | |||
| Oxy-combustion (OC) of Coal refers to using oxygen-enriched air as the oxidant. Compared to combustion with air, OC, coupled with staged combustion, intrinsically reduces NOx emissions and the elimination of nitrogen from the combustion air produces a CO2-rich, sequestration-ready flue gas. This session will explore the science and engineering opportunities to deploy OC technology into the nation's power production portfolio. Contributions are invited in the following: 1. recent results on oxycombustion of coal and other solid fuels; 2. burner redesign and retrofit options for OC; 3. ignition, devolatilization, and pollutant formation mechanisms during OC; 4. kinetic and CFD modeling of OC processes; 5. Engineering options for retrofitting; and 6. new OC boiler design - materials and engineering challenges. | |||
