  • the refractory protective cover is usually formed in rows and columns next to or above one another arranged plates.
  • Refractory walls are e.g. also used in fluidized bed ovens, where the boiler wall consists of a more or less thick simple metal wall. Again, the boiler wall or metal wall to be protected from corrosion.
  • the panels of the protective cover are usually mutually sealed by various measures to some extent to prevent the passage of flue gases. However, in practice this alone can not completely avoid that corrosive flue gases can pass through the protective cover and attack the boiler wall.
  • So-called ventilated wall systems address this problem by the fact that a protective gas - generally air - is pumped through the space between the boiler wall and the distance superior protective lining.
  • the gas or air is in this case with respect to the combustion chamber under a slight overpressure, which prevents the flue gases from penetrating from the combustion chamber into the wall space and can attack the boiler wall or other metal parts.
