Abstract:
Based on the Eulerian multiphase fluid model, 3D numerical models were established to simulate the coal gasification in fluidized bed. The gas phase was modeled with k-ε turbulent model and the particle phase was modeled with kinetic theory of granular flow. Submodels including heat transfer model, transfer model, species transport model and chemical reaction model were added to consider the dense gas-solid flow and chemical reactions in fluidized bed coal gasifier. Coal gasifications in a fluidized bed coal gasifier with diameter of 0.22 m were simulated. Composition profiles of gas product, temperature distribution of gas phase and chemical reaction rates under different operating conditions were obtained. Simulated results were compared with experimental values. The results show that numerical simulations are in well agreement with the experiments. The minimum relative error of simulation to the experiment is only 1%, the maximum relative error is about 20% and the mean relative error is less than 14%.
