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.
