Abstract:
The scarcity of coke has been long known to all the iron making units. Various attempts have been made to optimize the requirement of coke by developing alternative route for iron making, and alternative methods to meet the thermal requirement of the blast furnace iron making process. Most popular among these developments has been the development of coal injection in the blast furnaces at the tuyere level. In order to sustain Blast furnace route of iron making, cost and productivity need to be improved. Tata Steel has been practicing injection of coal in the blast furnaces at its Jamshedpur works since 1991. This paper describes the enhancement of injection rate at FBF with existing facilities from 150 kg/thm to 195 kg/thm.
