Application of Energy Saving Technology of Gas Operated Anode for Pre-baked Aluminum Reduction Cell

This paper describes the pre-baked aluminum reduction cell＇s energy saving principles and new gas operated anode, analyzes the advantages and disadvantages of traditional and new gas operated anode. Through contrast of practice on the aluminum reduction cell, it proved that the new type of gas operated anode is benefit to discharge anode gas, reduces the over-voltage and anode voltage drop bubbles effectively, decreases the ＂secondary＂ reactions, and improves the current efficiency achieving energy saving.
