Flow and Heat Transfer Simulation in a Flash Smelting Furnace

摘要

Fluid flow and heat transfer phenomena taking place in an industrial Outokumputype flash smelting furnace were simulated with CFD software CFD2000 1.0 and PHOENICS 1.6.6. The computational domains and grids are basically the same as described in earlier reports. However, some changes and simplifications are made to the grids, especially in the reaction shaft model. All the two-phase simulations presented in the report are cold and isothermal, where the particles exchange only momentum with the gas phase. As a first attempt, combustion of gaseous sulphur with oxygen was used to represent the heat release from the copper concentrate oxidation reactions. The results presented in the report are preliminary reflecting the different stages of the model development.
