  • Patent number: 8695345
    Abstract: In one embodiment, a calculation method of moisture loss in a steam turbine calculates first a wetness fraction at the inlet and outlet of each of stationary blade cascades and rotor blade cascades. Subsequently, the moisture loss is classified into (1) supersaturation loss, (2) condensation loss, (3) acceleration loss, (4) braking loss, (5) capture loss and (6) pumping loss, and a loss for calculation of the moisture loss is selected from the above losses (1) to (6) according to the wetness fraction of steam at the inlet and outlet of each blade cascade. An amount of each selected loss is calculated, and an amount of moisture loss at each blade cascade is calculated.

  • Patent number: 8195433
    Abstract: This invention provides an optimum value search apparatus, method, recording medium, and computer program product used in designing, analyzing, or testing a device having a plurality of factors that have effects on a characteristic. In this method, an orthogonal array is generated by setting level values obtained from the initial values of the factors to the coordinates of a two-dimensional table including a matrix of the characteristics and the factors. From the characteristics on the orthogonal array, characteristic values obtained on the basis of combinations of the level values of the factors of a single characteristic are grasped. A combination having a most excellent characteristic value is selected. The level values of the factors in the characteristic corresponding to the selected combination are reset in the orthogonal array. After resetting, processes are repeatedly executed to search for an optimum value as a most excellent one of the characteristic values.

  • Patent number: 8105038
    Abstract: A row of moving blades for a steam turbine has moving blades elongated radially which are arranged peripherally around and secured to a turbine rotor. The row also has an intermediate support structure for holding the blades to each other at a radially intermediate position. The support structure has a shape of a streamline cross section. The support structure may include a tie wire secured to the blades, or lugs protruding from the blades and combined to each other. The support structure may include lugs protruding from the blades to each other, and a sleeve combining the lugs. The shape of a streamline cross section may have an obtuse-angle or acute-angle upstream part.

  • Patent number: 7625181
    Abstract: A turbine blade cascade structure includes a plurality of blades arranged in series in a circumferential direction on a wall surface, in which a corner portion defined by the wall surface and a front edge portion of each of blade bodies supported by the wall surface, to which a working fluid flows, includes a cover portion (fillet) that extends toward an upstream side of a flow of the working fluid. The turbine blade cascade structure is capable of reducing the secondary flow loss of the secondary flow in spite of the fluctuation of an incident angle of the working fluid flowing to the front edge portion of the blade body.

  • Patent number: 5079091
    Abstract: According to the present invention, incineration ashes of sewerage sludge are compacted with pressure, but without additives, to have the bulk specific gravity of 0.9-2.5. Since the green compact has sufficient strength and reduced volume in comparison with the incineration ashes before compacting, it enables mass dumping without causing secondary pollution. Moreover, if the green compact is fired to have the bulk specific gravity of 1.4-3.5, both the volume and weight are reduced much more, realizing easy handling of the resulted burned product.
