Abstract Scope |
Smelters worldwide face increasing challenges regarding power cost, flexibility requirements from power grids, and emission reduction from fossil fuelled generation. Smelters can become responsible energy users by employing EnPot technology to pro-actively act as ‘batteries’ in power grids, to shed load and avoid coal/gas generation when renewables are insufficient, or take on extra load when excess power is available to increase production. The uncontrolled nature of cell heat loss has previously prohibited variable energy usage, however EnPot can enable this with a complete heat balance of the cell. An analysis of typical heat loss distributions for 160 to 390kA cells justifies how significantly reduced/increased power operation is achievable through control of cell heat losses. Further benefits of controlled heat loss are also described including benefits to cell control and life, as well as the uses of the waste heat collected. |
