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： A seal device for a turbine is disposed around a rotor so as to separate a high-pressure space and a low-pressure space and includes: a plurality of thin plates arranged along an outer peripheral surface of the rotor, each of the thin plates having a thin-plate tip surface facing the outer peripheral surface of the rotor; a first side plate disposed so as to face the high-pressure space and covering outer peripheral regions of first side surfaces, on a side of the high-pressure space, of the plurality of thin plates; and a second side plate disposed so as to face the low-pressure space and covering outer peripheral regions of second side surfaces, on a side of the low-pressure space, of the plurality of thin plates. The first side surface of each of the thin plates is covered with the first side plate in a region extending further to an inner side, in a radial direction of the rotor, than a region of the second side surface covered with the second side plate. A radial-directional position of the thin-plate tip surface of each of the thin plates has such a distribution that the side of the high-pressure space is farther away from the outer peripheral surface of the rotor than the side of the low-pressure space in at least a partial range of the thin-plate tip surface in an axial direction of the rotor, and the radial-directional position of the thin-plate tip surface at an axial-directional position closest to the high-pressure space is positioned on an inner side of an inner peripheral edge of the first side plate in the radial direction.
