Role of Coke and Burden Distribution Coke serves three critical functions: it provides the heat source, acts as the reducing agent, and supports the weight of the burden. Understanding the intricate steps involved reveals why the blast furnace remains a marvel of industrial engineering despite its ancient conceptual origins.

Cleaned gas is often used to fuel boilers for steam generation or sent to internal combustion engines for power generation, transforming a waste stream into a valuable energy source. The continuous nature of the process demands unwavering attention to stability, temperature, and gas flow to ensure consistent metal quality.
Maintaining thermal stability prevents the formation of disruptive conditions like hanging charges or furnace cooling, which can halt production. Hot air, blown into the furnace through tuyeres near the bottom, combusts coke to generate the necessary temperatures exceeding 1500°C.
