The invention relates to a thermal shielding brick (1, 1A, 1B), especially for lining a combustion chamber wall. Said thermal shielding brick has a hot side (5), which can be exposed to a hot medium, a wall side (7) located opposite said hot side (5), and a peripheral side (69) that is joined to the hot side and to the wall side. A damping element (3, 3A, 3B) is placed on the peripheral side and effectively prevents fragments (81,81A) from detaching from the thermal shielding brick (1, 1A, 1B) if broken. The invention also relates to a combustion chamber having an inner combustion chamber lining, which comprises said thermal shielding bricks (1, 1A, 1B), and to a gas turbine with a combustion chamber.
L'invention concerne une pierre servant de bouclier thermique (1, 1A, 1B), destinée notamment à garnir une paroi de chambre de combustion, avec une face chaude (5) pouvant être exposée à l'action d'un milieu chaud, une face de paroi (7) opposée à la face chaude et une face périphérique (69) jouxtant la face chaude et la face de paroi. Un élément amortisseur (3, 3A, 3B) est monté sur la face périphérique et protège très efficacement la pierre servant de bouclier thermique (1, 1A, 1B) de détachements intempestifs de fragments (81, 81A) de la pierre servant de bouclier thermique (1, 1A, 1B) en cas de rupture. L'invention concerne en outre une chambre de combustion comportant un habillage intérieur qui présente des pierres servant de bouclier thermique (1, 1A, 1B), ainsi qu'une turbine à gaz munie d'une chambre de combustion.
