A Comprehensive Assessment and Analysis of a Direct Reduced Iron Process
Pratyusha Nanda | Alok Sahai
Abstract: This particular study has been undertaken to quantity the Mass of material input to the rotary kiln of the Direct Reduced Iron process and the mass of output and energy associated with it. The various studies undertaken in the field reveals that the considerable quantum of mass and associated energy in the form of heat energy is not getting utilized and wasted. Today the energy market is so much volatile due to recent Ukrain war and is the need of the hour to increase focus on small improvements in improving efficiency of such processes, based on the energy assessment of the plant. This is a systematic way of assessment for taking suitable action for optimizing use of natural resources. This study is done based on real-time data analysis captured online for ensuring data quality and authenticity. For conducting such an analysis, the detailed study of the DRI process, co-relationships with all variables, energy content of various forms of coal, electricity, heat energy and power generation process was done. Further, study of accretion formation, temperature profile of the Kiln shell, dynamics of iron ore and their physical and chemical properties including the physical and chemical properties of coal, dolomite were conducted.
