agent to produce DRI of the time of this article has only rarely been reported [5]. The most comprehensive study by Yilmaz et al. [6] compared different types of DRI, including DRI partially produced by using hydrogen as reducing gas and their potential on the reduction of GHG emissions in a BF process. However, no modeling of the DRP was ...

Coal or coal briquettes enter the meltergasifier dome and are converted to char at 1100°C1150°C. Oxygen is blown into the melter gasifier and a reduction gas, mainly CO and H 2, is generated by gasifying the coal, which is fed to the upper reactor(s), reducing the burden. The reduced iron ore or hot DRI is charged into the melter gasifier ...
