摘要： An exhaust-side bearing rotatably supports a rotor of a turbine. A seal air-pipe and a first air-supply pipe supply compressed air extracted from a compressor of the turbine to the exhaust-side bearing. A second air-supply pipe supplies compressed air from a supplementary air-source to the exhaust-side bearing. A control apparatus switches between the first air-supply pipe and the second air-supply pipe based on the operation state of the gas turbine.

摘要： A gas turbine first-stage stator blade sealing structure for preventing the sealing air from leaking from the inside even if the blade falls or inclines due to thermal stress. A rear flange (12) of a first-stage stator blade (31) is formed in an arcuate shape having a straight rib (10). A stator blade support ring (13) contacts the straight rib (10) to form a sealing face. When the rear flange (12) and the stator blade support ring (13) fall or incline relative to each other due to thermal stress during operation, the upper end or lower end of the rib (10) contacts linearly with the face of the stator blade support ring (13) so that no clearance is established to inhibit leakage of the sealing air. In the prior art, where the horizontal rib (10) is absent, an arcuate clearance is established between the stator blade support ring (13) and the rear flange (12) as the support ring (13) inclines, and thus sealing air is allowed to leak from the inside to the gas passages.

摘要： Gas turbine combustor by-pass valve device for opening and closing a by-pass valve is improved to uniformly control air supply into a combustion area for appropriate combustion. A drive shaft 21 for opening and closing a driven by-pass valve 20 is provided in turbine casing 010 where an outside obstruction is located which would interfere with a projecting drive shaft 09. The driven shaft 21 has a short length to be provided in the turbine casing 010. An adjacent main driving shaft 23 for opening and closing main driving by-pass valve 22 is provided adjacent to the driven shaft 21. Link mechanism 26 is provided between the adjacent main driving shaft 23 and the driven shaft 21 so that rotary movement of adjacent main driving shaft 23 driven by outside drive means via the drive shaft 09 is transmitted to the driven shaft 21 and, thus, to the driven by-pass valve 20. Thus, partial drive shafts 09 are made shorter so as not to project outside of the turbine casing 010 and interfere with outside obstruction, but all the by-pass valves 08 provided along circumferential direction of the turbine casing 010 can be operated to be opened and closed uniformly.
