Oxygen carrier aided combustion (OCAC) in packed bed reactor (PBR) is simulated to investigate the dynamic operational characteristics. The one-dimensional heterogeneous model for OCAC-PBR is established by combining the models of porous media combustion (PMC) and chemical looping combustion (CLC). Model validation is achieved by comparing the temperature fronts of the current model with previous published PMC/CLC models. OCAC in PBR exhibits higher fuel conversion capacity under fuel-rich conditions, and relationship between temperature fronts and fuel conversion capacity is initially explored. The results reveal that the enhanced fuel capacity is attributed to the propagation of the heat front, heating more oxygen carrier (OC) to provide lattice at high temperatures. Consequently, the fuel conversion capacity of OCAC in PBR is influenced by the propagation velocity of heat fronts. OC has a limited impact on standing combustion waves under fuel-rich conditions, and its effect on moving combustion waves is negative, with reduced OC consuming gaseous oxygen before fuel/air combustion. To determine the conditions for achieving stable combustion waves, the investigation investigates the effects of inlet flow rate (Fin) and air-to-fuel ratio (Φ) on states of combustion waves. Flame in OCAC-PBR tends to propagate downstream with reduced combustion intensity and increased gas flow rate, resembling the behavior observed in PMC. However, combustion wave in OCAC displays less downstream propagation at higher Φ compared to PMC. Leveraging the capacity of OC to provide lattice oxygen under fuel-rich conditions, OCAC-PBR demonstrates enhanced resilience to fluctuations in Fin and Φ, thereby facilitating smoother operational stability.
