Reducing Gases

Metallurgical coke in the blast furnace provides a permeable matrix through which reducing gases may ascend and molten materials descend. A lack of permeability will inevitably lead to a poor gas distribution and result in a reduction of the furnace output and efficiency.A decrease in the permeability of the carbonaceous coke matrix arises when changes induced by the blast furnace environment occur in the properties of the material and effect the matrix voidage by causing a reduction of coke strength. A major influence of change within the blast furnace is the presence of recirculating alkali, particularly potassium, which is known to induce considerable microstructural changes (enhanced localised ordering), within the metallurgical coke. These microstructural changes lead to structural weakening as a consequence of a variety of factors:-

Gas and burden distributions inside a blast furnace play an important role in optimizing gas utilization versus the furnace productivity and minimizing the CO2 emission in steel industries. In this paper, a mathematical model is presented to describe the burden descent in the blast furnace shaft and gas distribution, with the alternative structure of coke and ore layers being considered. Multi-dimensional Ergun’s equation is solved with considering the turbulent compressible gas flow through the burden column. The porosity of each material will be treated as a function of three dimensional functions which will be determined by the kinetics sub-models accordingly. A detailed investigation of gas flow through the blast furnace will be conducted with the given initial burden profiles along with the effects of redistribution during burden descending. Also, parametric studies will be carried out to analyze the gas distribution cross the blast furnace under different cohesive zone (CZ) shapes, charging rate, and furnace top pressure. A good agreement was obtained between the CFD simulation and published experimental data. Based on the results, the inverse V shape is proved to be the most desirable CZ profile.
