Abstract

Irregularity of the rate field during the formation of streams in the reaction shaft of the flash smelting furnace is not enough investigated because of the influence of recirculation volumes. The uniform method of approach is not established for assessing their influence. These difficulties are raised from the lack of adequate and detailed description of physical-chemical, heat and kinetic processes running in the high temperature heterogeneous flame and short timescale of the particles with autonomic behaviour in the examined medium.

In this paper, the results from the simulation of the combustion process with the aid of ANSYS CFX are presented enabling visualization of the velocity and temperature fields in the reaction volume of the Outokumpu furnace.

Keywords: flash smelting furnace, computer simulation, temperature field, velocity field
