Abstract

The invention relates to a heat-shield brick, in particular for lining a combustion chamber wall, comprising a hot side that can be exposed to a hot medium, a wall side that lies opposite said hot side and a peripheral side that lies adjacent to the hot side and the wall side and that has peripheral lateral face. A tensioning element, pre-stressed in the peripheral direction is provided on the peripheral side, whereby a compressive stress generated perpendicularly to the peripheral lateral face. The invention also relates to a combustion chamber comprising a combustion chamber lining, which has heat-shield bricks of this type and to a gas turbine comprising a combustion chamber.
