<p>Title of Invention: IMPROVED HALL CELL An improved aluminum reduction cell which includes an insulated container for the molten electrolyte, a cover over the open mouth of the container, and a heat exchanger positioned above the molten bath, within the container and below the cover for recovering heat from the molten bath and further including, in one embodiment, means for converting the recovered heat into electricity which can be recycled back to the reduction cell. By heavily insulating the reduction cell against heat loss and by appropriately controlling the amount of heat which is recovered the cell can be operated over a wide range of electrical power inputs.</p> |
