Abstract
PURPOSE: To enable the direct welding of a nozzle box to a turbine shell in a steam turbine having two 180° nozzle boxes in the shell body by supporting the nozzle box through a telescopic loop to the shell.
CONSTITUTION: Two inlet tubes 2 are provided at the upper half of a turbine shell 1, and a flange coupling part 9 of reverse direction for coupling a steam supply tube to both the tubes 2 is provided. Nozzle boxes 6 of circular-arc shape of 180° are provided at the inside of the shell 1 under the tubes 2, and are controlled in the flowout steam quantity by a partition plate 18. The nozzle boxes 6 are supported by a nozzle tube 10, and an extension 11 is, for example, provided to prevent the axial movement of the nozzle boxes 6 while allowing the thermal movement of the nozzle boxes. A flange part 7 is provided at an intermediate tube of the steam guide tube to the nozzle boxes 6 is provided at the nozzle tube 10, a bent wall 8 is provided as a telescopic loop, and is fixedly welded to the turbine shell 1.
