    • A raw gas collection system for collecting raw gas from a plurality of aluminium smelting pots is equipped with a plurality of branch ducts (28d), each of which is arranged to channel a respective branch flow (38d) of raw gas from an aluminium smelting pot to a collection duct (26A), which is common to and shared by the branch ducts (28d). Each of said branch ducts (28d) is, near an outlet (52d) thereof, equipped with a curved section (50d) for aligning the branch flow (38d) with a flow direction of raw gas (27A) already present in the common collection duct (26A), and a constriction (54d) for accelerating the branch flow (38d) through the branch duct outlet (52d) into the common collection duct (26A). Furthermore, each of said branch ducts (28d) is equipped with a heat exchanger (40d) for removing heat from the respective branch flow (38d) of raw gas. The combined flow resistance of the constriction (54d) and the heat exchanger (40d) reduces the need for adjusting the respective branch flows (28d) using dampers, thereby reducing the power required to transport the raw gas.

    • An improved flue gas cooler (10), or bank of coolers (10), handles flue gas G from aluminium reduction cells in an aluminium smelter plant. The or each flue gas cooler (10) has a gas inlet chamber (14), a gas outlet chamber (16), and a matrix of gas cooling tubes (18) extending between the inlet chamber and the outlet chamber. Each cooling tube (18) has a bell-shaped inlet end (19) comprising an aerodynamically curved gas-accelerating profile effective to facilitate streamlined flow of flue gas G into the tube. The improved flue gas cooler makes it possible to connect the flue gas cooler to receive hot raw flue gas G direct from the aluminium reduction cells without getting clogged by dust and sublimates present in the flue gas. Once cooled, the flue gas can be safely passed on to a flue gas cleaning plant of the dry scrubbing type. The improved flue gas coolers are advantageously part of a system for using heat energy from the flue gas, in which a closed circuit coolant circulation system circulates coolant through the flue gas cooler and a heat exchange arrangement (24). Heat energy extracted from the coolant by the heat exchange arrangement (24) may be used to increase the efficiency of further plant coupled to the heat exchange arrangement.

    • The present invention concerns a method and an arrangement for use in an electrolysis cell system, comprising a hall with electrolysis cells (C) that use anodes of the pre-bake type for the production of aluminium. The invention comprises temporary storage of consumed anodes and other material that are removed from the cells in closable storage arrangements (A, B) arranged in the hall. The storage arrangements can be connected to an extraction system. Furthermore, during use, the storage arrangements (A, B) are placed at a distance from the cells (C) so that the operations performed on the cells are not obstructed by the storage arrangements. The storage arrangements (A, B) are also designed to be connected to an extraction system (4, 5) placed at a distance from the cells. The storage arrangements are specially designed with means to reduce emissions of gas to the surroundings and to enhance the efficiency of the cooling process. They are also designed to be transported by a vehicle (42).
