Rotary kiln coalbased DR plants, based on single module, are designed for up to a maximum of M tonnes per year (million tpy) of DRI, requiring high capital cost for larger capacities. When using ore fines and coal, gangue and sulfur stemming from coal is normally reflected in higher transformation costs in the steelmaking step.

Decarbonizing India's steel sector: opportunities and challenges

The scope for the adoption of these technologies depends on how steel is produced. There are two basic production routes: the Blast Furnace (BF) route, where coke is the primary fuel, and the Direct Reduced Iron (DRI) route, where the fuel can be coal or natural presently produces around 90% of crude steel through the BF and coal based DRI routes (with an approximately equal share ...

Direct Reduced Iron and its Production Processes IspatGuru

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.
