Pressurized fluidized bed combustion (PFBC) | IEA Clean

Pressurized fluidized bed combustion (PFBC) As with atmospheric FBC (CFBC or BFBC), the combustion temperature between 800-900°C has the advantage that NOx formation is less than in PCC, but N2O is higher. SO2 emissions can be reduced by the injection of a sorbent, and its subsequent removal with the ash.
