Corrugating of Furnace Walls

1. The internal furnace wall subject to compressive forces.
2. Small furnaces diameter and short length may be self-supporting if the wall thickness is adequate.
3. For larger furnaces, one of four methods of support may be used as below :

3.1 Corrugating the furnace walls
3.2 Dividing the furnace length into sections with as stiffening rings (Adamson ring) between section
3.3 Using welding stiffening rings
3.4 Installing stay bolts between furnace and the outer shell.
