Abstract: Deposits of unconverted particles in the heat recovery boilers used in the copper flash smelting process may cause operational problems. In this work, a dual-product layer shrinking-core-like particle model is presented. In this model the conversion can be solved from a single non-linear equation. Computational Fluid Dynamics (CFD) can provide detailed insight into the processes in the heat recovery boiler. Used with CFD, this particle conversion model can be used to study the effect of boiler design and process parameters on the depositing particles.
