(PDF) i) Direct Reduced Iron: Production

This product is known as direct reduced iron (DRI) or sponge iron. of DR technology has specified the characteristics of raw. coals for DRI production in rotary kilns. [7]

Coal based Direct Reduction Rotary Kiln Process IspatGuru

Rotary cooler The product (DRI) along with coal ash, calcined dolomite and residual char is discharged from the kiln at around 1000 deg C. An enclosed chute at the kiln discharge end equipped with a lump separator and an access door for removing lumps transfers the hot DRI to a rotary cooler.

Direct Reduced Iron Industrial Efficiency Technology

The counter-current rotary kilns used for DRI production in India only allow about 60% of the heat to be used for reduction, revalorization of the remaining 40% that is discharged from the kiln offers a significant potential for energy efficiency improvements.

based DRI occupies 17.6 million tonnes, which equates to 25.7% of the total1). Most coal-based reduction processes including SL/RN2) employ rotary kilns. Pellets, or lump-ore, mixed with coal are/is charged into the rotary kilns2) and heated by coal burners to produce DRI. To avoid the significant formation of the kiln rings, their

Direct Reduced Iron (DRI) International Iron Metallics

DRI can be either hot or cold charged to the EAF. Some steel companies ship DRI from their captive direct reduction plants to their remote steel mills and a small volume of DRI is sold to third parties. In India there are many small rotary kiln furnaces producing DRI, known locally as sponge iron, using coal as energy and reductant source.

Waste Heat Recovery for Rotary Kiln Direct Reduction

In this technology, DRI is produced in a rotary kiln of 3-6 m diameter and ~ 85 m length installed at an incline. The capacity of the kiln depends on metallization degree and usually does not exceed 225,000 300,000 t/y. It is operated in counter-current flow with solids moving down the incline in opposite direction to the gases. Iron ore and coal are jointly charged to the kiln from the
