New Generation Blast Furnace with Low Coke Consumption ...

The proposed new generation blast furnace has a higher exergy efficiency and lower carbon consumption, but the net energy consumption is marginally higher than in the conventional blast furnace. Preheating of the CO injected through the tuyeres using a low temperature heat source further increases the efficiency of blast furnace operation.

Ferro-coke utilization promises to reduce energy ...

Oct 01, 2017 · In conventional ironmaking, sintered iron ore is mixed with coke in a blast furnace to reduce the iron in the ore. In addition to the sintering step, the process requires high-grade coal in the coking ovens, and both steps are energy intensive. In the new process (diagram), the coke is partially replaced with ferro coke.
