  • SYSTEMS AND METHODS FOR CONTROLLING HEAT LOSS FROM AN ELECTROLYTIC CELL
    Publication number: 20200216971
    Abstract: Systems and methods for controlling heat loss from an electrolytic cell in a smelting process using an adjustable fluid passage to control the heat loss from a preferred area of the electrolytic cell side walls based on operating conditions in the electrolytic cell, and to direct the waste heat from the electrolytic cell side walls back into the electrolytic cell.
    Type: Application
