Abstract

Language:

This paper addresses the design of aluminum reduction cells that operate at approximately 11 kWh/kg Al, focusing on features that limit the heat loss from anode stubs and cathode collector bars. These design features, previously unmentioned, are examined in detail to reveal their contributions to reducing energy consumption. The methodology involves the modification of mathematical models that analyze design options, providing enhanced calculations of how these features impact cell heat balance. The improvements in the models allow for a more accurate exploration of design choices aimed at further decreasing cell power consumption while ensuring manageable superheat levels. The paper highlights the practical implications of operating with low cell voltages to minimize energy use, challenging conventional thinking by demonstrating the feasibility of low anode-cathode distances without compromising efficiency. Results indicate that operating with an internal heat generation that is minimal can be achieved through the selected designs, which ultimately lead to lower energy requirements. These findings offer significant insights for the advancement of energy-efficient aluminum reduction technologies.
