- Batch combustion experiments were performed in a small bubbling fluidized-bed reactorwith the objective of establishing the cause of reduced NOx emissions from pressurized fluidized bed combustion. All variables except for pressure were kept constant in the experiments: fuel batch size, for example, was the same in the experiments performed at three pressure levels (0.2, 1 and 2 MPa). Two types of experiments were conducted: one using air diluted with nitrogen and the other with NO-doped diluted air. A large excess of air was used in all cases so as to keep the bulk-gas composition relatively unchanged by combustion products. Different fuels were used: bituminous coal, coke and graphite.
