In the copper flash smelting process, deposition of dust particles can diminish the capacity of the heat recovery boiler. A deposit growth model was developed and implemented in a commercial CFD code to simulate deposition in a heat recovery boiler. In the model, a force balance of the particle landing on the wall is used as the deposition criterion. The thickness increase of the deposit layer is calculated from the mass flow of sticking particles. Simulations arc used to demonstrate the applicability of the model. They also help in providing insight into the process.
