Abstract: PROBLEM TO BE SOLVED: To operate a sequentially fired gas-turbine group on the basis of a positive control plan by opening one inlet vane blade row in a compressor to the pumping limit, igniting a first combustion chamber below the rated rotating speed during idling, and after opening the inlet guide vane row until reaching the rated rotating speed, igniting a second combustion chamber without changing the opening. SOLUTION: When starting, an inlet guide vane row in a compressor 12 is opened to a maximum up to the pumping limit of the compressor 12, and the ignition of a first combustion chamber 13 takes place below the rated rotating speed during idling. Then the inlet guide vane row is further opened to increase the rotating speed to idling. In the state of holding the opening of the inlet guide vane row, the ignition of a second combustion chamber 15 takes place. With the rotating speed kept as it is, the inlet guide vane row is further opened to sequentially increase the load of a gas-turbine group to full load.

Abstract: PROBLEM TO BE SOLVED: To provide a method of sequentially supercharging an internal combustion engine so as to assure a stable operation characteristic of the entire turbo supercharger of an internal combustion engine and match the turbo supercharger always to the optimum operating condition of the internal combustion engine. SOLUTION: When a load variation of an internal combustion engine is small, first the turbine lateral cross-section of at least a first exhaust gas turbo supercharger 3 is increased or decreased accordingly, and then aligned with a single or a plurality of turbine lateral cross-section. By this, when a specified switching time point where a load variation is not compensated for, one of the other exhaust gas turbochargers 4 is switched on or off. Upon one of the other exhaust gas turbochargers 4 is switched on or off, at least one turbine cross-section of the first exhaust gas turbochargers 3 is decreased or increased accordingly. Then, a produced load variation is adjusted accordingly to the turbine lateral cross-section of at least the first exhaust gas turbocharger 3 for new compensation.

Abstract: PROBLEM TO BE SOLVED: To provide a display for an overvoltage blocking device which is able to be economically operated again after responding and has a simplified structure. SOLUTION: An insulating material casing 6 is surrounded by a metal casing 4 of two components which holds a display element 16. A sensor and the insulating material casing 6 are components of a switching member 5. The both parts of the metal casing 4 are mutually shifted away so that the switching member makes the display element 16 visible by generating pressure gas when a fault current is generated and forms a conductive connection part which receives and releases the fault current.

Abstract: PROBLEM TO BE SOLVED: To provide a method of feeding fuel and an apparatus thereof, which has wide range of use and low in NOx emission by stabilizing combustion at a burner. SOLUTION: A burner is structured by arranging a pilot gas conduit pipe 15 only at the zone of a burner head 13 and as a parallel hole 15 with at least one axis inside the inner wall 4 of a main gas pipe 2. As a result of this, a pilot gas 16 is fed into an inside burner chamber 10, separately from fuel 11 and a blower air 12.

Abstract: PROBLEM TO BE SOLVED: To predict combustion states of all kinds of dusts in advance and to control them. SOLUTION: A heat generating amount of dust 1 to be ignited or a measured value for determining at least one heat generating amount is measured within a supplying shaft 2. This measured value is stored in a process control device 9. The amount of air supplied to a combustion grid or an amount of dust supplied to the combustion grid is controlled by this process control device, in cooperation with a value of the heat generating amount, when the dust 1 is ignited.

Abstract: PROBLEM TO BE SOLVED: To prevent a back pressure inside a compressor from exceeding a permissible value even if a pressure before a turbine increases following an increase in the quantity of steam via a driving nozzle by disposing an injector mechanism in an outlet diffuser connected to the downstream side of the compressor. SOLUTION: In the direct downstream side of a compressor 2, within the range of an outlet diffuser 3 connected to its place, pre-compressed air 13 is further compressed by the operation of an injector mechanism 20. For example, high pressure steam 10 generated in a waste heat steam generator 9 places a load on the driving nozzle of the injector mechanism 20, and thus the air 13 pre-compressed by the compressor 2 is further compressed. Lastly compressed air 6 is fed through a burner 5 into a combustion chamber 4. Heat gas 11 in the combustion chamber 4 puts a load or a turbine 7, and waste gas 8 from the turbine 7 is fed to the waste heat steam generator 9. By heat energy released from the waste gas 8, high pressure steam 10 is generated in the waste heat steam generator 9, and this high pressure steam 10 is supplied to an injector 21.

Abstract: PROBLEM TO BE SOLVED: To reduce harmful emissions, and prevent the additional thermal load of a component, by arranging air supply passages and blowoff hole inside a fuel injection part, by evening out the velocity profile of the flow in a wake region, and by lowering the temperature. SOLUTION: Air supply passages 5 and diffusion openings 6 with a diameter of about 1 mm as the means for evening out a velocity profile II and lowering the temperature in the wake region of a fuel nozzle 9 are arranged inside a fuel injection part 2. Consequently, the need for the action of a flame holder can be reduced according to the rate of diffusion, and additional air substantial flow 3 and main flow can be mixed well immediately in front of an injection point 10 for fuel, that is, before combustion. The setting of the rate of diffusion is preferably done, so that the blown-off air substantial flow 3 becomes smaller than 0.5% of the substantial flow of a high temperature gas. Thus, harmful emissions can be reduced, and the additional thermal load of a component can be prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce axial thrust, improve the cooling efficiency of blades and disks and contrive uniform temperature distribution in axial-flow gas turbines by disposing a suction device for removing leakage air and a portion of cooling air in the area of a drum labyrinth. SOLUTION: A main portion of cooling air to a rotor 3 is led into a wheel- side chamber 19 via lines 22 and swirl nozzles 23. A major portion of the swirling cooling air is introduced into a cooling duct 24 in the rotor 3, while a minor portion thereof is introduced into a gas duct in a turbine 1 defined between a turbine disk and a disk cover. Another swirl nozzle 23 spaced less radially from the principal turbine axis than the above swirl nozzles 23 guides separate cooling air toward the wheel-side chamber 19. The separate cooling air flows along an annular duct 20 from the opposite end of a compressor 10 until it is sucked, along with a leakage air mass flow trapped after a rearmost moving blade 11, by suction devices 25 disposed in the area of a drum labyrinth 21.

Abstract: PROBLEM TO BE SOLVED: To obtain a gate turn-off thyristor GTO, which does not make switching losses and can be actuated in a high switching frequency. SOLUTION: A GTO has anode emitters 6, a barrier layer 11, an N-type base 7, a P-type base 8 and a cathode emitter 9, including an anode side main surface 2. The anode emitters 6 are designed as transparent emitters and respectively have an anode short circuit 10. By a combination of the main surface 2, the bases 7 and 8 and the emitter 9 with the layer 11, the transparent anode emitters and the circuits 10, the GTO which is actuated in a high switching frequency, is obtained and although the thickness of a substrate of the GTO is reduced, the switching loss of the GTO is not increased.
