SAIL operationalises Rourkela Steel Plant’s blast furnace-4

The Coal Dust Injection (CDI) system has been operationalised in Blast Furnace 4 of Rourkela Steel Plant. This latest operational facility will result in improvement of techno economic parameters and enhance productivity of hot metal in the Blast Furnace.

The  CDI of Blast Furnace 4 has a design capacity of injection up to 100 Kg/Ton of hot metal, which will result in financial saving of approximately Rs 30 Crore per annum. Through CDI, the pulverized coal injection (PCI) facilitates consumption of cheaper coal in the system replacing the expensive coke thereby cutting down on cost. The facility will augment the efficiency and raw material optimization by facilitating direct consumption of coal and reducing coke rate.

CDI facility in BF-4 is a capital scheme which has been integrated with the ongoing expansion programme of the Steel Plant as a part of the massive modernization and expansion drive undertaken by Steel Authority of India Limited. SAIL Chairman C S Verma said that this energy efficient facility will enhance the productivity of blast furnace along with reducing the coke rate resulting in profit for the Plant.  

Earlier in April 2014, CDI facility was operationalized at BF – 5 of the steel Plant. It is a major energy conservation initiative undertaken by the Steel Plant. Almost all the new facilities under the expansion schemes at RSP have been completed and made operational. The benefits out of these have started accruing.
