MATHEMATICAL MODEL OF BLAST FURNACE Progress and Application to New Technology Development

摘要

Mathematical analysis of blast furnace processes has been tried at first by applying thermodynamics and then by kinetic and dynamic theory. Dissection analyses of industrial blast furnaces showed clearly non-uniform distribution of process variables, specifically existence of cohesive zone, which led to the development of multi-dimensional models. Continuum modeling has almost completed considering momentum, heat and mass transfer for reacting multi phase flow of gas, solids, liquids and fines.
