Abstract

The invention relates to the corrosion protection for a pipe wall (2) of a combustion chamber (1), comprising ceramic plates (5) that are mounted at a distance on the pipe wall on the combustion side. The intermediate space (6) between the pipe wall and the ceramic plates can be penetrated by a gas. Inlets (7), through which a gas, particularly outside air, can be sucked into the intermediate space (6), are disposed in the pipe wall.
