Furnace Smelting

The generating pathways of hydrogen chloride in blast furnace smelting process may have two pathways: 1.sodium chloride and water react with phosphorus pentaoxide forming hydrogen chloride gas.2. Sodium chloride and water react with sulfur dioxide and nitrogen dioxide forming hydrogen chloride gas. Based on Thermodynamic calculation of hydrogen chloride generation in blast furnace smelting process, hydrogen chloride gas is generated in the upper part of blast furnace shaft ,the generating temperature main range from 300°C too 800°C.

Flow Through

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.

Counter Current

The blast furnace process is a counter-current moving bed chemical reactor to reduce iron oxides to iron, which involves complex transport phenomena and chemical reactions. The iron ore and coke are alternatively charged into the blast furnace, forming a layer by layer structural burden which is slowly descending in the counter-current direction of the ascending gas flow. A new methodology was proposed to efficiently simulate the gas and solid burden flow in the counter current moving bed in blast furnace shaft. The gas dynamics, burden movement, chemical reactions, heat and mass transfer between the gas phase and solid phase are included. The new methodology has been developed to explicitly consider the effects of the layer thickness thermally and chemically in the CFD model.
