Description
technical field [0001] The invention relates to a gas distribution device and method. Background technique [0002] The use of oxygen-enriched air instead of air smelting in metal smelting is a major technical measure to strengthen production, reduce energy consumption, reduce environmental pollution, improve production efficiency, and increase economic efficiency. [0003] Oxygen-enriched smelting is to use the oxygen-enriched air blown into the furnace to undergo a violent oxidation reaction with the coke added to the furnace and the sulfide in the charge in the tuyere area of the furnace to generate a large amount of high-temperature furnace gas and high-temperature melt. In the process of rising through the material layer, mass transfer and heat transfer occur with the sufficient charge, the temperature gradually decreases, and the oxygen content gradually decreases, while SO 2 However, the concentration of the acid continues to rise, and then the high-temperature fan...
