In order to maintain stable operation in a blast furnace (BF) with higher productivity levels, blast enrichment and auxiliary fuel rates, it is important to have lowest possible degradation of coke during its travel from top to bottom of the furnace. This in turn demands proper understanding of the conditions coke has to face in the BF (i.e., effect of alkali, lime, other oxides, char/dust and reactions with surrounding gases) and mechanisms of fines generation and consumption in the blast furnace. In this work, a study on the role of coke and its functions in traditional as well as modern BF operation has been made, and mechanisms inducing and affecting coke degradation have been investigated and correlated with the actual experience from one of the best blast furnaces operating. Various efforts and improvements made toward optimization of coke quality at JSPL Raigarh are also discussed.
