Coal gasification for DRI production An Indian solution

Ral gas, direct reduction has provided much of the iron units required for growth in steel pro-duction. Direct Reduced Iron (DRI) produc-tion has increased tremendously since 1980, from essentially zero to over 21Mt in 2008, as shown in Fig 1. Of the total DRI production in 2008, 74% was produced from coal in rotary.

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.
