SYSTEM AND METHOD FOR CONTROL PF LAYER IN AN ALUMINIUM ELECTROLYSIS CELL

摘要

An objective of the present invention is to provide a method and system for use for control of layer formation over an extended area in an aluminium electrolysis cell and exploitation of heat. A second object of the invention is to provide a method and system for use for control of layer formation suited for retrofitting to an aluminium electrolysis cell and maintainability during operations of the cell. The present invention attains the above-described objectives by a flat heat tube for attachment to the steel casing of an aluminium electrolysis cell. This heat tube can be a heat pipe or a thermosyphon. Preferably the heat tube is provided with a substantially flat surface. Preferably the heat tube has a meandering shape.
