Blast Furnace - an overview ScienceDirect Topics

BFG is a by-product of the chemical reduction of iron ore in blast furnaces. It typically contains about 20–30% carbon monoxide (CO) and about 2–6% hydrogen (H2) as combustible components, and a significant amount of inert gases with about 45–60% nitrogen (N 2), and 20–25% carbon dioxide (CO 2) (see Table 14.1).
