Abstract:The software that simulates the flow, temperature, concentration and the heat generation field in the Out-kumpu flash smelting furnace, was developed by a numerical method of the particle-gas flow together with some chemical reaction models. Many typical operating conditions were chosen for simulation in order to obtain the effect of the distribution air, process air, central oxygen and the oil-burner position etc. The concepts about optimum operation, 3C(concen-tration of high temperature, high oxygen and laden concentrate particles), are concluded from these simulated results, which have been checked primarily by operational experiments.
Key words: numerical simulation; flash smelting furnace; optimum operation; copper smelting
