Description

図４は、ガスタービン燃焼器７のバーナ１８を構成する燃料ノズル１５と燃料ノズルプレート１４とを接合する比較例の接合方法を示したものであり、この図４に示した比較例の接合方法では、燃料ノズル１５の上流側近傍の側面４０ｂと、燃料ノズルプレート１４の下流側端部４１ｂとの双方を、燃料ノズルプレート１４に対して下流側から接合部４２を形成して接合している。 FIG. 4 shows a joining method of a comparative example in which the fuel nozzle 15 constituting the burner 18 of the gas turbine combustor 7 and the fuel nozzle plate 14 are joined. The joining method of the comparative example shown in FIG. Then, both the side surface 40b in the vicinity of the upstream side of the fuel nozzle 15 and the downstream end portion 41b of the fuel nozzle plate 14 are joined to the fuel nozzle plate 14 by forming a joining portion 42 from the downstream side . .
