Blast Furnace Gas (BFG) is a major byproduct of the ironmaking process.
BFG is produced as the reducing gas exits the top of a blast furnace. It is characterized by its high volume and low heating value, primarily composed of nitrogen (N2), carbon monoxide (CO), and carbon dioxide (CO2).
While it is often treated as a waste gas, its chemical energy is crucial for the integrated steel mill. We use BFG as a significant fuel source to power the entire plant, particularly in the hot blast stoves and power generation, thereby dramatically improving overall energy efficiency and reducing reliance on external fossil fuels.
