A stable and efficient operation of the ironmaking blast furnace is prerequisite to reduce the greenhouse gas emission. JSW Steel, Salem have been proposed many projects to reduce greenhouse gas emission, for example Higher O2 enrichment, H2 gas injection, Waste plastic injection, Natural gas and use of biomass reductant. Additionally, the operation stability and efficiency have a large influence on gas utilization and the rate of reductants and emissions, which are all important and mutually interdependent factors. This study leveraged advanced statistical tools, mathematical models, and technical research to assess the blast furnace process and detect anomalies. Subsequent to this analysis, a series of optimization measures were implemented, driven by the study's insights. These actions targeted blast furnace process enhancement, leading to heightened production rates, reduced fuel consumption, and diminished greenhouse gas emissions. This work epitomizes the commitment to harmonizing iron production efficiency with environmental sustainability.
