| Abstract Scope |
One of the technical pathways for the aluminum electrolysis industry to achieve deep energy saving is the efficient recycling of waste heat. In response to the technical challenges of low grade, large volume, and low recycling rate of flue gas, technologies such as intensified heat collection of flue gas, high-energy efficiency heat exchange of flue gas, and flue gas waste heat power generation system has been developed. These technologies do not affect the stable operation of aluminum electrolysis cells, efficiently recover waste heat from flue gas and utilize the recovered waste heat for power generation to return to the aluminum production system. Industrial tests conducted on 38 test cells in the 400kA series have shown that the waste heat recovery and utilization system achieves a more than 15% increase in intensified heat collection of flue gas and waste heat recovery power generation equivalent to over 60 kWh/t Al. |
