Abstract
And objective of the present invention is to provide an improved method and system for use for control of layer formation in an aluminium electrolysis cell and exploitation of the heat. The present invention attains the above-described objective by a reordering of the fundamental structure of a Hall-Héroult cell, providing two alternatives, eliminating the need for thermal insulation. In a first embodiment the ordering from the inside to the outside is: Electrolyte-sidelining-heat tubes-steel shell. In a second embodiment the ordering from the inside to the outside is: Electrolyte-sidelining-steel shell-heat tubes.

-8. (canceled)
A system for use for control of layer formation in an aluminium electrolysis cell and exploitation of heat comprising:
- a sidelining block (11);
- a shell (8);
- and
- a heat tube (12),
- wherein the sidelining block (11) is in thermal contact with the shell (8), and that the heat tube (12) is operable to remove heat from at least one of the sidelining and the shell.
A method for control of layer formation in an aluminium electrolysis cell said electrolysis shell comprising a sidelining block (11), a shell (8) and a heat tube (12), wherein the sidelining block is in thermal contact with the shell, and that the heat tube is operable to remove heat from at least one of the sidelining and the shell, characterized in conducting the heat away using said surface attached heat tube.
