摘要： PROBLEM TO BE SOLVED: To reduce energy consumption while controlling a cat-back phenomenon. SOLUTION: The gas turbine 1 is equipped with a first air supply passage 11 and second air supply passage 12 in a vertically upper part U of a cabin 5 for accommodating a combustor 4 for injecting to a turbine the combustion gas produced by burning fuel and air compressed by a compressor 3. The first air supply passage 11 discharges air toward the compressor 3 side inside the cabin 5. On the other hand, the second air supply passage 12 discharges air in a direction different from that in which the first air supply passage 11 does. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To unify the mixing ratio of a fuel and air in all combustion areas provided in the tail cylinders of respective combustors and generate a combustion gas optimum to the driving of a gas turbine, by a method wherein driving shafts and pivoting follower bypass valves are pivoted by follower shafts, which are pivoted by a neighboring main driving shaft. SOLUTION: A neighboring main moving shaft 23 and a follower shaft are arranged in parallel in the axial directions thereof and are connected by a connecting rod 25 through a link mechanism 26, so as to be pivoted through a link device by the movement of an outer wheel into the peripheral direction of a wheel chamber. In this case, the follower shaft 21 is pivoted by the pivoting of the neighboring main moving shaft 23, effecting the opening and closing operation of a main bypass valve, while the opening and closing operation of a follower bypass valve 20 is effected so as to be coping to the opening and closing operation of the main bypass valve 22. According to the method, the opening and closing motion of the follower bypass valve 20 can be effected even when the follower shaft 21 is not projected out of the wheel chamber whereby the mixing ratio of a fuel and air in the combustion area of respective tail cylinders of a combustor, which are arranged circumferentially in the wheel chamber, thereby permitting the increase of a combustion efficiency.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of a rotary machine by always maintaining a chip clearance at zero or minimum for the tip part of a fin and the inner peripheral surface of a sealing member by adjusting a spring elastic force and reducing the leakage of gas from a tip clearance part. SOLUTION: A fin 3 is formed in a reverse T shape, a base part 3b thereof is housed in a hollow part 2a, and a tip part 3a is protruded from a hole 2a in the outer periphery of a shroud 2 in a radial direction and is brought into contact with the inner surface of a honeycomb seal 6 as a sealing member. A compression spring 4 is erected between the upper and lower surfaces of the base part 3b of the fin 3 and between the upper and lower wall surfaces of the hollow part 2a. The tip 3a of the fin 3 is brought into contact with the inner peripheral surface of the honeycomb seal 6 with a small force by the elastic force of the spring 4. By adjusting the spring constant of the spring 4 and an attaching load for the pressing force of the fin 3, the tip 3a of the fin 3 is brought into contact with the inner peripheral surface of the honeycomb seal 6, i.e., a honeycomb end edge 6a, always by a small force.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of temperature difference between an air separator and a torque tube when unsteady temperature is changed so as to restrict the deformation inside of a gas turbine by providing single or plural torque tube cooling cavities near the outer surface of a stepped thick part of a torque tube from a turbine disc side. SOLUTION: Plural torque tube cooling cavities 9 parallel with a shaft and having flat cross section are provided near the outer surface of a stepped thick part of a torque tube 2 in the circumferential direction with equal pitch. Since the outer surface of the torque tube 2 is provided with the torque tube cooling cavities 9, heat capacity of this part is small. A part of the cooling air is flowed from a flow passage (a), and passed through the torque tube hole, and discharged, cooling the outer surface of the torque tube 2. With this structure, temperature difference between an air separator and the torque tube 2 is reduced when the unsteady temperature is changed, and the generation of adverse influence due to a difference in thermal deformation can be prevented.
