Title (EN) GAS TURBINE COMBUSTOR
(FR) CHAMBRE DE COMBUSTION DE TURBINE À GAZ
(JA) ガスタービン燃焼器
Abstract:
(EN) This gas turbine combustor is provided with: a plurality of swirling cylinders (31) that are arranged within a combustor liner (11) and that impart a swirling flow to a premixed gas (Fp) comprising fuel and combustion air mixed in advance; and an outer ring (15) arranged between the plurality of swirling cylinders (31) and the combustor liner (11) with a gap (41) between said outer ring (15) and the combustor liner (11), said outer ring (15) generating air (Af) in a film-like state within a combustor tail pipe (12) connected to the combustor liner (11) such that the air (Af) is jetted toward the combustor tail pipe (12) from the gap (41). The outer ring (15) comprises a tapered surface formed such that the thickness of the outer ring (15) on the downstream end (15d) thereof decreases gradually from the upstream side toward the downstream side.
(FR) La présente invention concerne une chambre de combustion de turbine à gaz qui est pourvue de : une pluralité de cylindres de tourbillonnement (31) qui sont agencés à l'intérieur d'une chemise de chambre de combustion (11) et qui confèrent un écoulement tourbillonnant à un gaz prémélangé (Fp) comprenant un combustible et de l'air de combustion mélangés à l'avance ; et une bague externe (15) agencée entre la pluralité de cylindres de tourbillonnement (31) et la chemise de chambre de combustion (11) avec un espacement (41) entre ladite bague externe (15) et la chemise de chambre de combustion (11), ladite bague externe (15) générant de l'air (Af) dans un état de type film à l'intérieur d'un tuyau de queue de chambre de combustion (12) raccordé à la chemise de chambre de combustion (11) de sorte que l'air (Af) soit éjecté vers le tuyau arrière de chambre de combustion (12) depuis l'espacement (41). La bague externe (15) comprend une surface conique formée de sorte que l'épaisseur de l'anneau externe (15) sur l'extrémité aval (15d) de celui-ci diminue progressivement du côté amont vers le côté aval.
(JA) 燃焼器内筒(11)内に複数配置され、燃料と燃焼用空気とが予め混合された予混合気(Fp)に旋回流を付与するスワラ筒(31)と、複数のスワラ筒(31)と燃焼器内筒(11)との間で燃焼器内筒(11)に対し隙間(41)を有して配置され、隙間(41)から燃焼器内筒(11)に接続された燃焼器尾筒(12)に向け噴射してフィルム状の空気(Af)を当該燃焼器尾筒(12)内に生成する外側リング(15)とを備え、外側リング(15)は、外側リング(15)の下流端(15d)に上流側から下流側に向けて厚さが漸減するように形成されたテーパ面を有するようにした。
