HOLLOW CURVED PLATE, METHOD FOR MANUFACTURING SAME, AND BURNER FOR GAS TURBINE

Hollow curved plates (20, 50, 70) include first plate members 24 1 -24 3 having a first groove 22 and second plate members 34 1 -34 3 having a second groove 32 of approximately the same width as the first groove 22, the second plate members 34 1 -34 3 being bonded to the first plate members 24 1 -24 3 by diffusion bonding. The hollow curved plate is formed of the first plate members 24 1 -24 3 and the second plate members 34 1 -34 3 curved by bending in a state where the first plate members 24 1 -24 3 and the second plate members 34 1 -34 3 are bonded together. The first groove 22 faces the second groove 32, a position of the first groove 22 substantially coincides with a position of the second groove 32 in a width direction, and hollow parts 40 1 -40 3 are formed by the first groove 22 and the second groove 32.
