Abstract
(EN)
In this method for preventing deformation of a gas turbine casing, a buffer tank (30) is installed inside a casing (10). The following are formed in the buffer tank (30): a stagnant portion agitation air port (52) for emitting a portion of the air from an air compressor (21) towards a stagnant portion (19) inside the casing as stagnant portion agitation air (Ga2); and an overall agitation air port (51) for emitting overall agitation air (Ga1) for agitating gas accumulated in the upper part of the casing. The buffer tank (30) is provided with a partition wall (36) in which is formed a through hole (53) which offers resistance to the air from the air compressor (21) so that the speed of the emitted overall agitation air is slower than the speed of the emitted stagnant portion agitation air.

L'invention concerne un procédé visant à prévenir la déformation d'un carter de turbine à gaz, et qui, pour ce faire, comporte un réservoir tampon (30) installé à l'intérieur du carter (10). Les éléments suivants sont formés dans le réservoir tampon (30): un orifice (52) d'air d'agitation de partie stagnante, qui dégage une partie de l'air provenant d'un compresseur d'air (21) en direction d'une partie stagnante (19) se situant à l'intérieur du carter, en tant qu'air d'agitation de partie stagnante (Ga2) ; et un orifice (51) d'air d'agitation global (Ga1), qui dégage de l'air d'agitation global pour agiter le gaz accumulé dans la partie supérieure du carter. Le réservoir tampon (30) est pourvu d'une cloison (36), dans laquelle est formé un trou traversant (53) qui présente une résistance à l'air provenant du compresseur d'air (21), de sorte que la vitesse de l'air d'agitation global dégagé est inférieure à celle de l'air d'agitation de partie stagnante dégagé.

 このガスタービンの車室の変形を防止する方法では、車室10内には、バッファタンク30が配置されている。このバッファタンク30には、空気圧縮機21からの空気の一部を車室内の淀み部19に向かって淀み部撹拌用空気Ga2として噴出する淀み部撹拌用空気口52と、車室内の上部空間に滞留する気体を攪拌する全体撹拌用空気Ga1を噴出する全体撹拌用空気口51とが形成されている。バッファタンク30には、全体撹拌用空気の噴出速度を淀み部撹拌用空気の噴出速度よりも低くするために、空気圧縮機21からの空気の抵抗となる貫通孔53が形成されている仕切壁36が設けられている。
