Abstract
In recent years, fluidized bed reactors are applied to the regeneration process of oxygen carriers. The regeneration performance of oxygen carriers will have a direct influence on the fuel conversion and the ability of oxygen transfer of oxygen carriers. For this reason, considering the effects of non-uniform structures in fluidized bed reactors, the regeneration process of oxygen carriers in fluidized bed is investigated by means of simulation. Gas-solid flow behavior and temperature field in fluidized bed are obtained. The impact of air to fuel ratio on the oxygen conversion rate is evaluated. The results indicate that a high air to fuel ratio will reduce oxygen conversion efficiency. By comparison with experimental data, the model with consideration of multi-scale structures can obtain a better prediction.
