HEAT-SHIELD BRICK, COMBUSTION CHAMBER COMPRISING AN INTERNALCOMBUSTION CHAMBER LINING AND A GAS TURBINE

摘要

The invention relates to a heat-shield brick (1), in particular for lining a combustion chamber wall, comprising a hot side (3) that can be exposed to a hot medium, a wall side (5) that lies opposite said hot side (3) and a peripheral side (7) that lies adjacent to the hot side (3) and the wall side (5) and that has a peripheral lateral face (9). A tensioning element (11), p re- stressed in the peripheral direction is provided on the peripheral side (7), whereby a compressive stress is 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.
