According to Primetals Technologies, the addition of the fourth stove to the No. 5 blast furnace will enable IISCO to repair existing stoves without impacting plant production or efficiency.

“The internal-combustion-technology stove includes a range of innovative features — including a ‘mushroom dome’ developed for longer equipment lifetime due to its stable refractory design and a vertical ceramic burner to enable good mixing and efficient combustion. In addition, the hot blast mains will be extended to accommodate the fourth stove,” Primetals Technologies said in a statement.

Primetals Technologies will be responsible for the design, engineering, manufacturing and construction of the new stove shell. The supply also includes high-grade refractories, expansion joints, hydraulic systems and valves along with the hot blast main extension and associated support and access structures.

The new stove is to enter service within 17 months of the contract signing.
