摘要
The influence of three important operation parameters in Jinlong flashsmelting furnace, including the distributing blast speed, the oxygen enrichment rate of process airand the ratio of central oxygen to overall oxygen (O_c/O_o), has been investigated using a virtualsimulation system on copper flash smelting furnace. The core of this virtual simulation system is anumerical simulation of CFD (computational fluid dynamics), and this system incorporates couplingmomentum transport, heat transport, mass transport, reaction kinetics between gas and particles andchemical reactions between gas and gas. A set of numerical predicted data were obtained. The CFDsimulation shows that there is a sensitive zone of the distributing blast speed, and the dustcontent ascends when the speed exceeds 180 m centre dot s^(-1). Increasing the oxygen concentrationof processing air benefits the efficient production of the flash smelting furnace.
