摘要

Outokumpu公司的闪速熔炼炉(FSF)技术是目前应用最广泛的铜冶炼方法之一。通过建模来了解工艺参数对冶炼操作的影响是提高冶炼效率的关键。虽然已经报道了几种模拟FSF的数值方法,但本文重点介绍了计算流体动力学(CFD)建模的详细方法,该方法通过结合进料矿物学和冶炼反应动力学克服了早期模型的局限性。在Dahej Birla Copper的FSF模型中,考虑了反应轴和沉降器干舷作为主要发生气固相反应的区域。该模型提供了FSF操作的详尽信息,有助于可视化炉内发生的现象。进行了参数化研究,验证和论证了各工艺参数对冶炼的影响。

CFD modelling of copper flash smelting furnace – reaction shaft
ABSTRACT Flash smelting furnace (FSF) technology by Outokumpu is one of the most widely employed methods for copper smelting. Developing an understanding of the impact of the process parameters on smelting operation through modelling is the key to improve the smelting efficiency. Though several numerical approaches for modelling the FSF have been reported, this paper focuses on a detailed approach of computational fluid dynamics (CFD) modelling which overcomes the limitations of the earlier models by incorporating feed mineralogy and smelting reaction kinetics. The FSF based at Birla Copper, Dahej was modelled considering the reaction shaft and settler freeboard as the domain, where most of the gas-solid phase reactions occur. This model provides an exhaustive information on the FSF operation which aids in visualizing the phenomena occurring inside the furnace. A parametric study was done to validate and demonstrate the impact of various process parameters on smelting.
