In coalbased DRI process, accretion formation inside the rotary kiln is a genuine complex problem. Accretion formation in a rotary kiln of 100 tpd DRI plant has been investigated. The nature of accretion formation with respect to the charge burden and operational parameter have been discussed. High ash content in the coal and excess use of dolomite lead to accretion formation. Two different ...

The MXCOL technology combines a gasification plant and MIDREX shaft furnacebased DRI plant capable of producing steel with lower capital cost than integrated steel manufacturing (Hasanbeigi et al., 2013). The offgas from the DRI plant is recycled with fresh syngas after removing CO 2 using a scrubber (MxColUsing Syngas to make DRI, 2014).

One of the greatest advantages of coal fired plants is reliability. Coal's ability to supply power during peak power demand either as base power or as offpeak power is greatly valued as a power plant fuel. It is with this fact that advanced pulverized coal fired power plants are designed to support the grid system in avoiding blackouts.

The DRI is either melted in an EAF plant adjacent to the DR plant or transported to other plants as either DRI or hot briquetted iron, HBI, for further processing. Since the reducing gas from natural gas contains 66% hydrogen, the CO 2 emission is considerably lower compared to the use of coke or coal as a reductant.

Direct Reduced Iron and its Production Processes. Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using noncoking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known ...

vi. Good compatibility with the reductant coal used. The ore used in most of the coal based sponge iron plants hardly meet the above requirements. The availability of such ore is difficult as it calls for selective mining and also the extent of such reserves are limited. Reductant Coal is the most critical input material for rotary kiln sponge ...

Most of the Indian DRI plants use coalbased processes due to less investment, lowergestation period, easy availability of coal, and limited accessibility of gas. The overall capacity utilization of the DRI plants stands low, at about 60%. The poor quality of iron ore further results in lower yield of the sector.

The naturalgasbased DRI processes, however, limit plant locations to places where natural gas is available. On the other hand, coalbased DRI plants are flexible as to plant location, because coal is widely distributed in large deposits and is easy to transport. This has significantly increased the production of coalbased DRI.
