Influence of bed condition on gas flow in Corex melter gasifier

Abstract

The Corex process, which consists of the upper reduction shaft and a melter gasifier is an alternative ironmaking process to the blast furnace. The melter gasifier, where final reduction of iron ore and melting of direct reduction iron take place, plays an important role in the process. In order to evaluate the gas flow under different solid bed conditions in the melter gasifier, a two-dimensional static model has been developed. The results reveal that the bed void which is caused by particle diameter and their manner of packing significantly influences gas flow in the gasifier. A 'V' shaped bed is preferred to provide the optimum gas flow in the gasifier.
