Abstract: In a steam turbine plant in which a turbine casing containing a turbine is constituted of an upper-half casing and a lower-half casing, nozzles are provided to the upper-half casing and a steam supplied through main steam piping lines are delivered into the upper-half casing. Main steam pipes for supplying a steam from respective main valves to the respective nozzles are each formed so as to be dividable in a position out of the installation area of the upper-half casing.

Abstract: A power generating plant comprises: a boiler; a steam turbine to be driven with steam generated in the boiler; a power generator to be driven according to the rotation of the steam turbine; a strut for supporting the boiler; a base mounting the steam turbine thereon; and a frame for supporting the base. The steam turbine is disposed above the boiler, and the strut for supporting the boiler is used as the frame. Thus, it is possible to package the steam turbine equipment and the boiler, thereby reducing a construction site for the power generating plant.

Abstract: A boiler installation supporting frame structure supported by a supporting structural body and a gas turbine frame base are constituted integrally, and a gas turbine device is disposed at upper portion of the integrated type frame structure and at the lower portion thereof a boiler installation is disposed in a three dimensional structure. Thereby, through the three dimensional arrangement of the gas turbine device and the boiler installation, the power generation installation can be disposed in a limited space.
