摘要： A fuel injection device for supplying a fuel to a compressed air includes: a pilot fuel injector; a main fuel injector located at an outer periphery of the pilot fuel injector; and an air injection unit located between an outlet end portion of the pilot fuel injector and the main fuel injector. The air injection unit includes: a partition wall plate separating the air injection unit from a combustion chamber; a flame stabilization plate provided at a downstream side of the partition wall plate; a first opening at a downstream side between the flame stabilization plate and the outlet end portion of the pilot fuel injector; and a second opening provided in the partition wall plate and through which the compressed air is supplied. The flame stabilization plate includes an inclined portion inclined in a radially outward and downstream direction with respect to an axis.

摘要： A fuel injection device for a gas turbine combustor includes: a pilot fuel injector; a main fuel injector; a plurality of main fuel injection holes arranged in the main fuel injector to inject the fuel rearward; a main fuel injection nozzle to guide the fuel to a main air passage, protruding rearward from a circumference of the main fuel injection hole into the opening formed in a passage wall that forms the main air passage; a heat-shielding casing covering the main fuel injector; and a ring member interposed in an axial gap between the passage wall and the heat-shielding casing. The ring member covers a through-hole gap between the main fuel injection nozzle and a through-hole in the heat-shielding casing, and has a purge passage communicated with the opening to introduce air into the main air passage.

摘要： 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.

摘要： A fuel injector includes a pilot fuel injector, configured to inject the fuel into a combustion chamber, and a main fuel injector provided coaxially with the pilot fuel injector so as to surround the pilot fuel injector and configured to have a main flow path to generate a premixed air-fuel mixture. The main flow path includes an outer main air passage located radially outwardly and configured to supply a compressed air in an axial direction into an annular premixed air-fuel mixture passage, an inner main air passage located radially inwardly and configured to supply the compressed air into the premixed air-fuel mixture passage from a radially inner side. The injector further includes a main fuel injection port to inject the fuel from an axially upstream side into the inner main air passage.
