| 英文摘要 | The fluidized magnetic roasting is recognized as the most effective treatment of low-grade/complex iron ores for the sustainable development of steel industry. For a deeper investigation of the technology, the computational fluid dynamics (CFD) simulation of this gas-solid reaction process is conducted through combining the intrinsic chemical kinetics with random nucleation model, which shows a good agreement with the experimental data for considering the mixed-effect of mass transfer resistance and nucleation mechanism. Furthermore, in order to predicate the gas-solid noncatalytic reaction rate more accurately, the contribution of mass transfer within the bubble phase has been also taken account for the bubbling bed approach. It is demonstrated that the fluid dynamics, chemical kinetics and heterogeneous flow structure determine the fluidized roasting behavior simultaneously. (c) 2020 Elsevier Ltd. All rights reserved. |
