Flue wall structure of pre-roasted anode roaster

The utility model relates to a flue wall structure of a pre-roasted anode roaster. For two sides of a high temperature flame combustion area of each flue wall of the pre-roasted anode roaster, one side is provided with 8 bricks, and the other side is provided with 5 bricks. Three high-alumina bricks are arranged at the side provided with 8 bricks at intervals, and two high-alumina bricks are arranged at the side provided with 5 bricks at intervals. The flue wall structure has simple structure and high operability; due to the `8+5` brick structure, the non-deformability and the flexural capacity of the high temperature flame area can be improved; as different bricks are chosen based on the temperature in different positions, the service life of the flue can be prolonged to above 30 furnaces; the heavy repairs of the flue wall can be reduced; and the purpose of lowering energy consumption is achieved.
