    摘要: An object is to provide a combustor that requires a small mounting space for an acoustic damper, that can achieve size reduction, and that can improve the ease of maintenance. A combustor (5) of the present invention includes a combustion cylinder (19) that defines a combustion area (23) therein and an acoustic damper (31) that has a damper cover having an acoustic-damper resonance space communicating with the combustion area (23). The damper cover is provided along the combustion cylinder (19) so as to extend in a direction intersecting an axial direction (L) of the combustion cylinder (19).

    摘要: In a gas turbine that generates rotational power by supplying fuel to compressed air compressed by a compressor and burning the fuel in a combustor and supplying resultant combustion gas to a turbine, a circumferential distance starting from a leading edge of a turbine first stage nozzle toward a trailing edge side of the first stage nozzle and ending at center of transition pieces of such combustors that are adjacent in a circumferential direction is set relative to a circumferential pitch of such first stage nozzles within a range of 0.05≦S/P≦0.15, and an axial distance between a leading edge of the first stage nozzle and a transition piece rear end of the combustor is set relative to the circumferential pitch of the first stage nozzles within a range of 0.00≦L/P≦0.13. By improving the relative position of a transition piece of the combustor and the first stage nozzle, both suppression of inner pressure fluctuations of the combustor and enhancement in aerodynamic efficiency can be achieved.

    摘要: An object of the present invention is to provide a gas turbine that improves appearance of a combustion oscillation suppressing device disposed to a transition piece of a combustor. To achieve the object, a combustion oscillation suppressing device 34 is disposed to a transition piece 32 of a combustor to define a gas space S, and has a plurality of vent holes 343 through which a gas space L and the inside of the transition piece 32 communicate with each other. The combustion oscillation suppressing device 34 has: a first member 341 that has a substantially U-shaped cross-section formed by press-working, and is disposed on the outer circumference of the transition piece 32 with a substantially U-shaped cross-section opening thereof facing the transition piece 32; and a second member 342 that defines the gas space S between the first member 341 and the second member 342 by blocking the substantially U-shaped cross-section opening of the first member 341, and has the vent holes 343. In a radial-direction cross section of the transition piece 32, when the outer diameter of the transition piece 32 varies along an axial direction of the transition piece 32, distances d1 and d2 from the axis L of the transition piece 32 to each bent portion of the first member 341 having a substantially U-shaped cross-section are set to be substantially equal.
