Abstract: A liquid pressurizing apparatus, comprises a tank provided on a device installation surface for storing liquid so that a fluid level is located above the device installation surface; and a vertical pump including a suction port connected to the tank, multi-stage impellers arranged in a vertical direction, and a discharge port for discharging the liquid passing through the multi-stage impellers. The multi-stage impellers include a first stage impeller positioned at the lowest part of the multi-stage impellers and being configured such that the liquid from the suction port flows into the first stage impeller. The first stage impeller is disposed below the device installation surface.

Abstract: A turbine rotor blade row includes: a plurality of turbine rotor blades disposed along a circumferential direction of a hub. An inter-blade flow channel has a first cross-sectional shape perpendicular to a radial direction of the hub at a first position in the radial direction, and a second cross-sectional shape perpendicular to the radial direction of the hub at a second position farther from the hub than the first position in the radial direction. The first cross-sectional shape has a throat portion between an inlet and an outlet of the inter-blade flow channel in an axial direction of the hub.

Abstract: An impeller includes a disk, a long blade that is disposed at an interval in a circumferential direction on a disk surface on a first side in an axial direction of the disk, and that reaches an outer peripheral edge of the disk, and a short blade that is disposed between the long blades adjacent to each other on the disk surface, and that reaches the outer peripheral edge. A circumferential length of the short blade gradually increases as the short blade faces outward in the radial direction, and a circumferential length of the long blade in the outer peripheral edge is smaller than the circumferential length of the short blade in the outer peripheral edge.

An inter-blade flow channel has a first cross-sectional shape perpendicular to a radial direction of the hub at a first position in the radial direction, and a second cross-sectional shape perpendicular to the radial direction of the hub at a second position farther from the hub than the first position in the radial direction. The first cross-sectional shape has a throat portion between an inlet and an outlet of the inter-blade flow channel in an axial direction of the hub. An expression A1/B1>A2/B2 is satisfied, where A1 and A2 are flow-channel widths of the first cross-sectional shape at the outlet of the inter-blade flow channel and at the throat portion, respectively, and A2 and B2 are flow-channel widths of the second cross-sectional shape at the outlet of the inter-blade flow channel and at the same position as the throat portion in the axial direction of the hub, respectively.

Abstract: A low-pressure-vapor-recovery turbine generator that effectively recovers low-pressure steam emitted from a high-pressure-side steam turbine to generate electric power is provided. A low-pressure-vapor-recovery turbine that recovers low-pressure steam emitted from a high-pressure-side steam turbine and is rotationally driven, a generator that generates electric power with a rotational output of the low-pressure-vapor-recovery turbine, and a condenser that condenses into liquid exhaust steam from the low-pressure-vapor-recovery turbine are provided. The low-pressure-vapor-recovery turbine, generator, and condenser are installed in a portable outer casing that can be transported.
