FIG. 1 is a draWing displayingtheinsidecon?gurationfromthesidevieW. [0040] AsshoWninFIG.1,the?rstradial?oWsteamtur bine 100 comprises a rotation shaft 10, a rotor disk 20, a stator disk 30 and a casing 40 as basic parts. FIG. 1 only shoWs the basic parts, so other parts such as peripheral parts and pipes are omitted here in order to explain simply and focus on the operationprinciple. [0041] Therotationshaft10issupportedforfreerotation by a bearing not shoWn in the ?gure. The material of rotation shaft 10 is not especially limited, but for example it is a stiff-high strength material in order to secure its stiffness for toleratingdangerousrotationspeedhigherthanthemaximum speed of rotations in the operation range for the radial ?oW steam turbine. There is no danger that the rotor blades crash into each other by adopting a stiff enough axis in order to suppress the occurrence of the resonance oscillation. [0042] Therotordisk20isconnectedtotherotationshaft 10,anditrotatesbytheforceWhichisgiventotherotorblade 21 by the operating steam ?oWing from the center portion to the outside in the radial direction as shoWn beloW. The rotor disk 20 rotates together With the rotation shaft 10. [0043] Therotorblade21ismountedintherotordisk20. Therotorblade21may beanimpulsebladetypeorareaction blade type. Hybrid composition may be possible. For example,theblademountedontheperipheralpartmay bethe impulse blade type and the blade mounted on the inner part thereactionbladetype.Forexample,therotationalspeedof theinnerpartissloW,andthesteampressedbythestatorblade 31 can hit the rotor blade 21, so it is preferable that the impulse blade type be adopted to this portion. On the other hand,therotationalspeedoftheperipheralpartisfast,andthe steam pressed by the statorblade 31 cannot hitthe rotorblade 21 suf?ciently, so it is preferable that the reaction blade type be adopted to this portion. Regarding the steam ?oW Width, themore thesteam?oWs totheouterportion,thenarroWerthe Width becomes. Therefore, the more the steam ?oWs to the outer portion, the loWer the pressure of the steam becomes and the faster the speed of the steam becomes. In this condi tion, the rotation force is generated on the rotor blades by converting the heat energy into the rotation energy. The rotor blades 21 can be mounted on either one surface or both surfaces of the rotor disk 20. For improving the output e?i ciency,therotorblades21aremountedontobothsurfacesof the rotor disk 20 in this Embodiment. [0044] Intheradial?oWsteamturbine100,thenumberof blades 21 is not limited. In this con?guration, one stage of the rotorbladescomprisespluralrotorbladesarrayedannularly on concentric paths, and the multi-stage rotor blades com prisespluralstagesmountedontherotordiskarrayedannu larly on concentric paths. The con?guration shoWn in FIG. 1 usesthefourstagesofthemulti-stagerotorblades.Theinstal lation position of the rotor blades 21 on the rotor disk 20 are on the outer part of the through opening 22 because the throughopening22existsinthevicinityoftherotationshaft. Theexamplecon?gurationusingasinglestagerotorblade21 is described in Embodiment 2 later on. [0045] Thethroughopening22isanopeningexistinginthe vicinity of the rotation shaft on the rotor disk 20, itWorks as a part for securing the steam supply route passing the steam ?oW through the axial direction. Regarding the radial ?oW steam turbine 100 of the present invention, the steam should beintroducedfromthesteamsupplysource(itisnotshoWnin ?gure) up to the operating steam ?oW passages inWhich the steam travels in the out?oW direction along the radial (in a perpendiculardirectionrelativetotherotationshaft)formed betWeen the rotor disk 20 and the stator disk 30. The through opening 22 in the vicinity of the rotation shaft Works as a part of the steam supply route. As shoWn above, the steam ?oWs along the axial direction via the through opening 22 on the rotor disk 20, so even ifthe sets ofrotor disk 20 and stator disk 30 are added to the rotation shaft 10, su?icient amount of operatingsteamcanbesuppliedtoeveryturbineunitandhigh output can be obtained.
