Description
Summary:Luossavaara Kiirunavaara AB (LKAB) supplies customized iron ore products for blast furnaces and direct reduction processes. The products are mainly pellets, and today LKAB operates five pelletizing plants located in Malmberget and Kiruna, Sweden. A research programme together with MEFOS was initiated during 2005 to meet future demands for lower emissions and to improve the process efficiency in general. Computational Fluid Dynamics (CFD) has been chosen as a tool for the development due to the characteristics of the pellet induration process. A heat transfer model for a porous bed applied on cooling of pellets for the Grate-Kiln process is described and another example focusing on combustion in kiln is briefly
