A ring (100) for forming a cooling-air layer is attached to the liner (11) of a combustion chamber, to supply cooling air fed from a compressor from a cooling-air supply hole (41). During the operation of a gas turbine, the cooling air is allowed to flow from a gap (51) formed between the ring (100) and the inner surface of the liner (11) of the combustion chamber, to form the cooling-air layer on the inner surface of the liner (11) of the combustion chamber.
L'invention concerne un dispositif combustor de turbine à gaz. Un anneau (100) donnant forme à une couche d'air de refroidissement est adapté à un tube interne de chambre de combustion (11). L'air de refroidissement qui émane d'un compresseur, via un trou d'alimentation correspondant (41), est fourni à l'anneau: cet air s'écoule depuis un espace (51) constitué par l'anneau (100) et la surface de paroi intérieure du tube (11) susmentionné, au cours du fonctionnement de la turbine à gaz, formant la couche d'air de refroidissement sur la surface de paroi interne du tube (11) en question.
