22/04/2017· One important characteristic of the Energiron direct reduction plant is the possibility to design the process for a zero make-up water requirement. This is possible mainly because water is a by-product of the reduction reaction since it is condensed and removed from the gas stream.

The process principles are the basis for numerous rotary kiln plants and still represent the dominant technology for the direct reduction of lump ore or pellets using coal. Operates with the widest range of iron-bearing materials, such as pellets, lump ore, beach sand, ilmenite and also iron ore fines with SL/RN-Xtra.

The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.

Direct reduction is a process for reducing iron ore in the solid state. It requires much less capital investment than the BF process and requires no coke. Therefore, DR plants have nbeen built mainly in oil and natural gas producing countries to supply raw iron for EAF processes.

The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted Iron (HBI) and Cold Briquetted Iron (CBI); also Low Reduced Iron (LRI), which is pre-reduced iron ore with a reduction and metallisation

The four horizontal rotary kilns are the heart of the reduction process. The residual char (carbon) remaining after the coal was heated is used to achieve the chemical reduction of iron oxide to iron. A number of chemical reactions occur in the kilns because coal and ironsand are not pure substances like laboratory chemicals.
view moreDirect reduced iron (DRI), produced by the reaction between iron ore and reducing gasses, is used as a source of low-residual iron, in addition to ferrous scrap and pig iron, in the production of steel mainly through the electric arc furnace (EAF) route of steelmaking.
