Superheat Measurement System

    Conventional methods of achieving energy efficiency in modern smelter plants, like resistance control, optimized feed strategy, etc. has almost reached a saturation point and it is unlikely that further significant improvements in current efficiency figure can be obtained by these methods. Therefore, alternative methods of enhancing the cell performance are being actively pursued by scientists and engineers in the industry. One of the most promising paths towards this goal has been to achieve stable cell operation by maintaining thermal balance of the cell. The method requires accurate measurement of Superheat.

New approach to achieve stable cell operation:  Combined stabilization of mass and energy.

Method involves direct measurement of:

    Superheat - the difference between the bath temperature and the liquidus Based on the measurement, an approximate control algorithm is applied to each cell so that optimum stability is obtained resulting in an increase in current efficiency and reduced energy consumption.
