Abstract
Official abstract text for this publication.
A raw gas collection system ( 15 ) for collecting raw gas from a plurality of aluminum smelting pots ( 4 ) is equipped with a plurality of branch ducts ( 16, 16 a - d ). Each branch duct ( 16, 16 a - d ) is arranged to channel a respective branch flow ( 32, 32 a - b ) of raw gas from an aluminum smelting pot ( 4 ) to a collecting duct ( 20 a ), which is common to and shared by branch ducts ( 16, 16 a - d ). Several of the branch ducts ( 16, 16 a - d ) are equipped with a combined heat transfer and flow resistance generating element ( 17 ) to remove heat from the respective branch flow ( 32, 32 a - b ) of raw gas and to balance the flow of raw gas in the raw gas collecting system ( 15 ). The combined heat transfer and flow resistance generating elements ( 17 ) reduce the need for adjusting the respective branch duct ( 16, 16 a - d ) flow volumes using dampers, thereby reducing the power required to transport the raw gas through the system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A raw gas collection system for collecting raw gas from a plurality of aluminium smelting pots comprising: a plurality of branch ducts each fluidly connected to a respective aluminium smelting pot of said plurality of aluminium smelting pots, for each of the branch ducts to channel raw gas from a respective branch duct inlet at the smelting pot to a respective branch duct outlet; a first common collecting duct fluidly connected to said plurality of b…
