Institute of Chemical Engineering page 8 Achema 2012 Chemical Process Engineering Project Group Oxyfuel Combustion OxyFuel… is a key technology for efficient separation of CO 2 from combustion of fuels. performs combustion of fuel with pure or enriched oxygen (mixing flue gas with pure oxygen). allows improved operation for low calorific fuels thanks to the possibility of variation of O 2 content at the inlet. entails an energy penalty comparable or even less than for pre and post combustion CO 2 capture. in CFB can reduce formation of thermal NO X compared to PCC.
