Fossil fuel combustion is one of the major means to meet the mounting global energy demand. However, the increasing NOxand N2O emissions arising from fossil fuel combustion process have hazardous effects. Thus, mitigating these gases is vital to attain a sustainable environment. Interestingly, oxy-fuel combustion in fluidized bed for carbon capture and minimized NOxemissions is strongly sustainable compare to the other approaches. It was assessed that NOxformation and fuel-N conversion have significant limitation under oxy-fluidized bed compared to air mode and the mechanism of NOxformation is still deficient and requires further development. In addition, this review paper discussed the potential of primary measure as low emission process with others supplementary techniques for feasible NOxreduction. The influences of combustion mode, operating parameters, and reduction techniques such as flue gas recirculation, oxygen staging, biomass co-firing, catalyst, influence of fluidized bed design and structure, decoupling combustion and their merges are respectively evaluated. Findings show that significant minimization of NOxemission can be achieved through combination of primary and secondary reduction techniques. |
