Analyze the new technology of flue gas waste heat recycling of submerged arc furnace from the principle and structure,and collect the actual production data to analyze and compare the changes before and after the utilization of the flue gas waste heat through calculation.The heat exchanger is set up in the flue of the submerged arc furnace,and the exchanged heat is transferred to the secondary air of the rotary kiln,so as to reduce the discharge temperature of the flue gas of the submerged arc furnace and increase the temperature of the secondary air of the rotary kiln entering the kiln.The results show that this technology reduces the amount of flue gas cooling water of the submerged arc furnace,reduces the smelting power consumption of the submerged arc furnace,and reduces the consumption of pulverized coal in the rotary kiln,improves the discharge temperature of the calcined ore in the rotary kiln,and improves the thermal efficiency of the rotary kiln.
