EXAMINATION OF CHEMICAL-LOOPING COMBUSTION OF GASEOUS FUELS BY 1-DIMENSIONAL MODELING AND EXPERIMENTS

摘要：

　　This work presents a l-dimensional model for the fuel reactor in chemical looping combustion (CLC) with gaseous fuels.Modeled fuel conversion is in good agreement with experimental data from a 300W CLC unit using syngas as fuel and ilmenite as oxygen carrier.The sub-model for the solids fluid dynamics is based on semi-empirical expressions derived and typically used in regular fluidized bed air combustion.These expressions have here been experimentally validated for conditions relevant to chemical looping combustion with data from a 100 kW CLC unit and a cold flow model of the same unit.Fuel conversion is modeled accounting for both heterogeneous and homogeneous kinetics and assuming a classical two-phase flow approach for which the influence of the correlation chosen for the gas interchange coefficient is found to have a slight influence the results.
