Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method of operating a gas turbine including a sequential combustor arrangement and a closed loop cooling portion.SOLUTION: A gas turbine (1) includes a sequential combustor arrangement (4). In the turbine (1), the combustor arrangement (4) includes a first combustor with a first burner (106) for admitting a first fuel (28) into a combustor inlet gas during operation and a first combustion chamber (101) for burning the first fuel (28), a dilution gas mixer (27) for mixing a dilution gas (33) to the first combustor combustion products (35) leaving the first combustion chamber (101), a second burner (103) for mixing a second fuel (29), and a second combustion chamber (102). To assure a temperature profile after the dilution gas mixer (27) and to increase the gas turbine's power and efficiency, a vane (11) and/or blade (10) of the turbine (5) has a closed loop cooling portion.SELECTED DRAWING: Figure 1
【課題】シーケンシャル燃焼器配列と閉ループ冷却部とを備えるガスタービンを作動させる方法に関する。【解決手段】シーケンシャル燃焼器配列(4)を備えたガスタービン(1)であって、前記燃焼器配列(4)は、作動中に燃焼器入口ガスに第1の燃料(28)を供給する第1のバーナ(106)と第1の燃料(28)を燃焼させるための第1の燃焼室(101)とを有する第1の燃焼器と、第1の燃焼室(101)から出てくる第1の燃焼器燃焼生成物(35)に希釈ガス(33)を混合する希釈ガス混合器(27)と、第2の燃料(29)を混合する第2のバーナ(103)と、第2の燃焼室(102)とを備えているガスタービン(1)に関する。希釈ガス混合器(27)後の温度プロフィールを保証しガスタービン(1)の出力と効率を向上させるためにタービン(5)のベーン(11)及び/又はブレード(10)は閉ループ冷却部を有している。【選択図】図1 |
