Abstract:
With the aim of improving the process efficiency of FINEX technology, a thermodynamic optimization was suggested in this paper. By the two-stage fluidized CO reduction experiments of iron ore fines, the relationship between the previous stage and the followed stage were investigated. The results show that the reduction degree of the followed stage firstly increased and then decreased with increasing the temperature of the previous stage. This indicates that the reduction degree of the followed stage is strongly depending on the reduction temperature of the previous stage. Thus, the thermodynamic analysis of the iron ore reduction was carried out to clarify the optimization principle. Based on this, a high reduction degree with low energy consumption was finally achieved.
