Abstract: A shroud assembly of a gas turbine includes a holder including an insertion hole, a plate-shaped shroud main body covering the holder from a radially inner side and made of a ceramic matrix composite, and a plate-shaped insertion member made of the ceramic matrix composite. The shroud main body includes a main body portion, a flange portion, and an insertion hole formed at the main body portion. The insertion member includes an insertion portion inserted into the insertion hole of the shroud main body and the insertion hole of the holder in an axial direction, and a head portion arranged at the radially inner side of the flange portion of the shroud main body and configured to be brought into contact with the flange portion from the radially inner side.

Abstract: A fuel injection device for a gas turbine combustor includes a pilot fuel injector disposed on an axis of the fuel injection device; an annular main fuel injector encircling the pilot fuel injector; and a plurality of main fuel injection holes formed in the main fuel injector and spaced circumferentially from each other for injecting fuel axially rearward. The main fuel injector includes an annular fuel passage forming portion, an inner ring portion on an inner peripheral side of the fuel passage forming portion, and an outer ring portion on an outer peripheral side of the fuel passage forming portion. One of a space between the fuel passage forming portion and the inner ring portion and a space between the fuel passage forming portion and the outer ring portion forms a pilot fuel supply passage, and the other one forms a main fuel supply passage.

Abstract: A fuel injection device includes: a pilot fuel injector disposed at a radially center position; a main fuel injector having an annular shape and disposed so as to encircle the pilot fuel injector; a fuel injection portion that injects a fuel into a combustion chamber; a fuel supply unit that supplies a fuel to the fuel injection portion; a fuel introduction portion secured to a combustor housing that has the combustion chamber therein and introduces a fuel into the fuel supply unit; and an injector housing that is supported by the fuel introduction portion and covers front portions of the pilot fuel injector and the main fuel injector. The fuel supply unit has a base supported by the fuel introduction portion, and an annular body supported by the injector housing via a support pin so as to be radially movable relative to the injector housing.

Abstract: A fuel injection device for injecting an air-fuel mixture to a combustion chamber in a combustor of a gas turbine engine includes a fuel injector which is arranged on an axis of the fuel injection device. The fuel injector includes a fuel injection portion for injecting fuel in the radial direction of the fuel injection device, a fuel flow path portion forming a passage through which fuel is supplied to the fuel injection portion, and a heat shield cover that covers an end portion facing toward the combustion chamber side of the fuel injection portion such that an air layer is formed between the heat shield cover and the end portion.
