Abstract:Flash Converting Furnace (FCF) in Jinguan Copper has been put into practice since 2013, continuous optimization of operational parameters has vital influence on improving furnace operating conditions. In the early stage, the parameters were optimized based on experience, and were not supported by theoretical data. For this reason, numerical simulation of copper FCF was carried out, and orthogonal test was used to analyze influence of different operational parameters and find the most suitable parameters for copper FCF. The results show that the lower speed of process air, together with higher oxygen concentration of process air and larger flow rate of distribution air, the lower mass fraction of O2 in flue gas goes down at uptake shaft outlet. Compared to standard working condition, mass fraction of oxygen in flue gas at uptake shaft outlet drops from 8.32% to 6.37%, and utilization rate of oxygen rising from 88.96% to 92.67% is obtained under the optimized case found out through orthogonal test.
