reduced in its solid state using either coal or natural gas as a fuel. One advantage of this method is that iron can be added as lumps, pellets, or fines, and if coal is used, it does not need to be coked. Therefore, a sinter/pellet and a coke plant is not needed for this operation. The end product is called direct reduced iron or DRI.

A Case Study on Accretion Formation in Rotary Kiln of DRI Process

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 ...

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 as the direct reduction (DR) processes.
