%X A modification scheme was put forward to change the straightly distributed air in the central jet distributor(CJD) concentrate burner into rotarily distributed air in copper flash smelting furnace,and simulations were carried out to investigate the distributions of velocity,temperature and concentration fields of both the gaseous and particle phases in two burner schemes.Comparison of two simulation results show that the rotarily distributed air is more conducive to improvement of the mixing and reaction process between the gas and particles,which will result in the increase of oxygen utilization by 4.5%,however,as small particles tend to be more easily affected by the rotarily distributed air,the dust generation rate will also increase in such a condition.
