Abstract: PROBLEM TO BE SOLVED: To reduce the compression terminal temperature or compression work by providing a compressor part having a plurality of water injecting means, and connecting means for water-heat exchanging cooling water to the water injecting means through a feed pump. SOLUTION: A water conduit line 10 is extended along a constant pressure compressor 1A, and feed pipe line 11 are branched from the water conduit line to compressing stages. The injection of water is performed within a passage through injection nozzles 12, and the injection nozzles are arranged in lattice within the passage. A mixture of partially compressed combustion air and steam is sent to a cooler 5 through the outlet of the constant pressure compressor 1A, and cooled until the steam is perfectly condensed. The condensate formed within the cooler 5 is collected into a vessel 13. The condensate is returned into the water conduit lines 11 and the injection nozzles 12 through a regulating device 15 by a field pump 14. Thus, an additional constituting member causing a pressure loss is omitted, and an injection fitted to the flow can be performed.

Abstract: PROBLEM TO BE SOLVED: To ensure a simple and compact structure by connecting a main gas annular conduit with a main gas supply pipe line upstream and connecting a pilot gas annular conduit with a pilot gas supply pipe line upstream, and connecting the main gas annular conduit and the pilot gas annular conduit with an annular combustor downstream. SOLUTION: A main gas annular conduit 13 and a pilot gas annular conduit 14 are connected with a main gas supply pipe line 15 or a pilot gas supply pipe line 16 upstream, respectively, and are connected with an annular combustor 1 downstream. In operation of a gas turbine main gas introduced into the main gas annular conduit 13 through the main gas supply pipe line 15 and the pilot gas supply pipe line 16 and pilot gas introduced into the pilot gas annular conduit 14 are distributed to a main gas pipe 18 and a pilot gas conduit 19 of a double cone burner 4 in a pressure resistant burner hood 3. All connection parts of the fuel pipings are welded to improve reliability of the operation of the gas turbine.

Abstract: PROBLEM TO BE SOLVED: To obtain a new converter circuit device including GTOs which is operated by using snubber elements as small as possible and whose occupation space and cost are reduced. SOLUTION: A branch of a converter circuit device which comprises first and second gate turn-off thyristors GTO1, GTO2 with respective inverse-parallel connection diodes D1, D2 is shown in the Fig. The positive and negative terminals of a DC power supply which are represented by the terminals of a capacitor Czk of an intermediate circuit are connected by this branch. A voltage-buildup limiting means is only one capacitor C1 or C2 every branch. This C1 or C2 is connected in parallel with one of the inverse-parallel connection diodes D1, D2 which is also connected in parallel with the corresponding GTO thereto. This capacitor C1 or C2 is assigned to either GTO1 or GTO2.

Abstract: PROBLEM TO BE SOLVED: To wedge the slot of a stator thin plate bucket only in the axial direction by a slot closing member by forming constitution in which a fastening jaw is engaged with a first prismatic body through a projection. SOLUTION: A wedging device 1 is movably disposed in a support frame 23 through a lift device 22, and when a fastening jaw 2 with a punch 8 is positioned to slot closing members 12, 14, the wedging device 1 is moved toward the slot closing members 12, 14 by the lift device 22. At that time, a projection 3 slides into the axial slot 11 of a slot wedge 12, and also the punch 8 is engaged with the end surface 13 of a tongue piece 14, and at the time of the hydraulic operation of a piston 6 they come nearer to each other like a screw clamp and the tongue piece 14 is pushed into under the slot wedge 12 and force toward the insulator 19 of a conductor rod 20 functions to the bottom part of the slot. As a result, the slot closing members 12, 14 are controlled and can be fixed in a rotating machine.

Abstract: PROBLEM TO BE SOLVED: To perform the transfer from a normal operation start-up drive state to a controlled load drive state without pressure drop by supplying heat inside the exhaust gas flow of a gas turbine to a flow-through regulator for feed water flow. SOLUTION: By a three-component control, a level regulator 13 changes the set value Sollein , using the flow-through regulator 14 for feed water flow, which is subordinated to a superordinated level regulator 13. The water level in a drum 6 is always regulated to the set value Soll, regardless of interfering effects. In this method, heat QAG in the exhaust gas flow of a gas turbine is supplied to the flow-through regulator 14 for feed water flow. With this, overall water level regulation is performed and the transition from the normal operation start-up drive state to the controlled load drive state can be performed without pressure drop and without changing the structure of a regulation cycle.

Abstract: PROBLEM TO BE SOLVED: To make it possible to easily separate a fine fraction, to shut off air from an incinerating chamber, and to cool down the second fraction, by separating a fine fraction containing toxic substances in a dry process, and by further treating a coarse fraction containing little toxic substances in a wet process. SOLUTION: A slag generated on the grate in an incinerator is directly discharged into the first screening stage 3 constituted of a screen-conveyer-type grate. Then, the slag is separated into the fine fraction having a particle size of up to 2 mm and the coarse fraction having a particle size of over 80 mm. The coarse fraction is fed to a wet deslagger (a removing apparatus) 4 which simultaneously shuts off air from the coarse fraction side in the incinerator. The fine fraction is fed to the second screening stage 5 through a screw conveyer 10 and a double flap valve 11, where it is screened. The fraction having a particle size of under 2 mm is fed to a fusion furnace 7, and a fraction having a particle size of over 2 mm is fed to a comminuting stage 6 and is comminuted there. Then, it is fed to a classifying stage 9 and further to the third screening stage 8 and is fed to the fusion furnace 7 after screening.
