Description
Summary:The character of the flow motion in the operating space of an Outokumpu furnace for flash smelting determines the peculiar features of the technology. Physicochemical and thermal processes proceed under the conditions of a high-temperature multiphase multicomponent medium. Physical simulation makes it possible to study and visualize the flow in similar media and to study the influence of various factors on the operation of the anaggregate. In this article, with the help of a laboratory model of a reaction shaft and a charge burner, the conditions of the formation of flow recirculation in the reaction volume of a flash furnace are studied.
