| Abstract Scope |
Building on the scientific and practical knowledge outstanding energy efficient smelting cell designs have been developed that are energy efficient and environmentally responsible. With constraints arising from regional availability of energy and the substantial cost of supporting infrastructure , capacity creep by increasing amperage on the installed capacity provides the best way of satisfying the growth in demand for the metal. Invariably design and operating retrofits become desirable or necessary because of heat balance and other constraint. Adverse performance and operating characteristics, such as a substantial reduction in cell life or reduced efficiencies. The root cause is invariably being due to changes of transfer processes - the physics of getting the consumables or energy to or from the reacting sites at the rate required in order to maintain the desired uniformity in the cell. Hitherto this has been ignored - avoiding or minimising is the next challenge. |
