Problems solved by technology

Therefore, when the transition piece has a tapered shape, creases tend to occur on the bent portion of the press-worked first member.
Therefore, I am worried that the performance of the sound-absorbing surface and structural surface of the product will be reduced

Abstract

A gas turbine enabling an improvement in the appearance of a combustion oscillation reducing device disposed on a tail pipe of a combustor. A combustion oscillation reducing device (34) is disposed on a tail pipe (32) of a combustor to form a gas space (S) and causes the gas space (S) and the interior of the tail pipe (32) to communicate with each other via ventholes (343). The combustion oscillation reducing device (34) includes a first member (341) and a second member (342). The first member has a cross-sectional substantially U-shape formed by press work and disposed at the outer periphery of the tail pipe (32) with an opening of the cross-sectional substantially U-shape facing toward the tail pipe (32). The second member closes the opening of the cross-sectional substantially U-shape of the first member (341) to form the gas space (S) with the first member (341) and includes the ventholes (343). When the outer diameter of the tail pipe (32) changes along the axial direction of the tail pipe (32) as viewed in radial cross-section of the tail pipe (32), distances (d1, d2) from an axis (L) of the tail pipe (32) to bent portions of the cross-sectional substantially U-shape of the first member (341) are set to an almost constant value.

Description

technical field [0001] The present invention relates to a gas turbine, and more specifically, to a gas turbine capable of improving the appearance of a combustion vibration reduction device disposed on a transition piece of a combustor. Background technique [0002] In recent gas turbines, in order to reduce the combustion vibration generated by the combustor, a combustion vibration reducing device (acoustic lining) is provided on the transition piece of the combustor. As a conventional gas turbine having such a configuration, the technology described in Patent Document 1 is known. The current gas turbine combustion vibration reduction device (modular resonator) is a module-shaped resonator in a gas turbine power plant that defines flow paths for the compressor, combustor assembly, transfer unit, and turbine assembly. A first member having a small diameter and having a plurality of openings formed therein, and a second member maintaining a spaced relationship with the first...
