SUMMARY:Numerical simulation on the effect of various chute dimensions on burden distribution during the charging process in a blast furnace
DESCRIPTION:Burden-charged distribution in the top region of the iron-making blast furnace is an important issue, as the non-uniform distribution in this part may affect the gas flow, heat transfer, and chemical reaction inside. The rotary chute plays the role to deliver material from the hopper to the furnace top, and it comes in different sizes, which will eventually establish distinct particle movements while charging. In that regard, it is vital to understand the fundamentals of particle movement that determine burden distribution inside a blast furnace in corresponds to chute sizes. In this study, a three-dimensional model of the furnace-top and rotating chute was established to clarify the material movement and burden distribution of ore and coke (O/C), investigated at the particle scale using the discrete element method (DEM). Case studies of various chute sizes (length and diameter) were varied to analyze their influence on material flow behavior inside the chute during charging. The change of heap profile of O/C centralized or peripheralized layers during charging was analyzed on the effect of various chute sizes. In addition, the cross-section of ore and coke layers was examined, where the layer thickness and volume fractions on radial distance of each case were mapped and compared.
