    摘要: 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.

    摘要: 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.

    摘要: 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.
