Abstract: An object of the present invention is to provide a gas turbine power generator capable of increasing the power generation efficiency in partial load operation and decreasing a variation in the number of rotations caused by a variation in power generation load. The gas turbine power generator comprises a compressor (2) for compressing air, a combustor (5) for burning the compressed air and fuel, a turbine (6) driven by combustion gas produced in the combustor and driving the compressor (2) and a generator (7), a regenerative heat exchanger (4) for exchanging heat between exhaust gas from the turbine and the compressed air led into the combustor, an intake air sprayer (1), and a humidifier (3). Intake air flown into the regenerative heat exchanger (4) is humidified and cooled by the intake air sprayer (1) and the humidifier (3).

Abstract: A heat and electric power supply system includes a regenerative gas turbine and an adsorption refrigerator recovering exhaust heat of exhaust gas from the gas turbine and is provided with inlet air cooling equipment including a spray device for spraying cold water from the adsorption refrigerator into an air-intake port of the regenerative gas turbine and a humidifier effecting humidification by hot water injection from the refrigerator into a compressor delivery port of the regenerative gas turbine. The cooling by cold water and humidification by hot water injection are effected according to operational conditions.

Abstract: A turbine blade of a low blade profile loss with a crossing point of an inlet angle .alpha..sub.1 an outlet angle .alpha..sub.2 being located in a position in which a distance between a crossing point of the outlet end of the blade is greater than one-half of the blade width L.sub.ax, with the inlet angle .alpha..sub.1 being in the range of 35.degree.-40.degree. and the outlet angle .alpha..sub.2 being in the range of 25.degree.-28.degree.. A ratio of a narrowest width S.sub.2 of the flow channel at the blade outlet end to a narrowest width S.sub.1 of a flow channel defined between a backside of the blade in an area of the crossing point and a front side of adjacent blade lies in the range of 0.81-0.96. A ratio of a distance L.sub.ax to a blade width L.sub.ax is in the range of 0.5-0.54, with a ratio of a distance L.sub.m from an outlet end of the blade to the blade width L.sub.ax being in a range of 0.75-0.89.

Abstract: In a blade lattice structure for an axial fluid machine including circumferentially arranged stationary blades and upper and lower side walls having the stationary blades secured thereto for defining therebetween a flow path which is arranged annularly, the stationary blades each have a cross sectional shape such that the thickness of each stationary blade gradually increases in going toward the upper side wall from an arbitrarily selected position on the blade in its height, so that the area of a throat for each section of the stationary blade is varied along the height thereof to thereby increase stage efficiency.

Abstract: A diaphragm for an axial flow fluid machine comprising inner and outer walls for defining an annular fluid flow passage therebetween, a blade lattice having a plurality of stationary blades disposed in the fluid flow passage, each of the blades having a concave side surface and a convex side surface, adjacent two stationary blades defining an inter-blade fluid flow path together with the inner and outer walls, a suction port open to a first portion of the fluid flow path adjacent to the concave side surface and the inner or outer wall to suck the fluid therefrom, a blowoff port open to blow off the fluid to a second portion of the fluid flow path adjacent to the inner or outer wall and at which the pressure is lower than that at the first portion, and a passageway for communicating between the suction port and the blowoff port, thereby reducing the secondary flow loss and the blade configuration loss in the blade lattice.
