The present application relates to a fuel supply device for a gas turbine, which can supply a first fuel and a second fuel having a high combustion speed to a combustor of the gas turbine. In the present device, a first fuel supply line and a second fuel supply line are merged at a merging portion and are connected to the combustor via a mixing line. The second fuel supply line is provided with a first shutoff valve serving as a controlled object when the combustion state is switched from a single fuel combustion state to a mixed fuel combustion state, and a flow meter provided upstream of the first shutoff valve. The flow meter can output a detection value of a flow rate of the second fuel in order to calculate a mixing ratio of the first fuel and the second fuel for monitoring an operating state of the gas turbine.

Fuel supply device for gas turbine and method for controlling fuel supply device for gas turbine

A control device selects and executes any of normal control of outputting a fuel flow rate command value through feedback control based on a deviation between a target output and an actual output of a gas turbine and load decreasing control of outputting the fuel flow rate command value for reducing an output of the gas turbine to a predetermined target output during a predetermined first time without performing feedback control, and performs control of reducing a flow rate of air flowing into a compressor of the gas turbine such that an air-fuel ratio settles within a predetermined range, in parallel with execution of the load decreasing control when the load decreasing control is selected.

Control device, gas turbine, control method, and program

A gas turbine fuel supply system includes a fuel supply flow passage that includes a fuel gas heater which heats fuel and supplies the fuel heated by the fuel gas heater to a first nozzle and a second nozzle, a bypass flow passage that supplies the fuel to the first nozzle without passing through the fuel supply flow passage, and a bypass fuel flow rate adjusting valve that adjusts a flow rate of the fuel flowing in the bypass flow passage.

A combustion temperature high speed detection device is provided with a phase lead processing portion, thereby canceling out a detection lag of a temperature detector, and detecting the combustion gas temperature of a combustor at a high speed. The combustion temperature high speed detection device is also provided with a first-order lag filtering portion with a time constant of 0.25 second, a phase lag processing portion with a time constant of 10 seconds, a temperature change filtering portion with a cutoff frequency of 2 to 3 Hz, and a disturbance filtering portion including first-order lag filtering portions with different time constants and a high value selecting portion. Thus, high speed detection of the combustion gas temperature more suitable for a gas turbine system can be performed.

Herein disclosed is a discharge side indicator device for use with a cash discharge apparatus. The cash discharge apparatus comprises a bill discharge machine and a coin discharge machine located thereon. The discharge side indicator device includes two pairs of indicator plates of sector shape, one of which is disposed on the bill discharge machine, and the other of which is disposed on the coin discharge machine. The indicator plates are located on the opposite sides of the bill discharge machine and the coin discharge machine so that they may be moved into and out of the body of the machines. A driving mechanism is used to alternately drive the indicator plates, when energized, so that they may be rotated so as to be protruded or retracted from the front face of the money discharge exits. This driving mechanism is electrically controlled by a suitable control system. Thus, an operator is made aware that it is permissible to remove money only from the side at which the indicator plate is retracted.

An apparatus for counting bendable sheets and discriminating different kinds thereof has a plurality of rotary suction heads for deflecting the sheets one at a time away from a stack of sheets held in a vertical direction on a holder and has a system for optically detecting the height of a sheet deflected away from the stack. Each of the suction heads has at its top a supporting member for engaging with the surface of a sheet which has been deflected away from the stack. The deflected sheet is engaged at its opposite surfaces with the supporting members of two adjacent suction heads, thus being supported in an upright state without bending downwardly.

Apparatus for counting sheets and discriminating different kinds thereof

There is provided a register apparatus. The register apparatus includes a key input device for successively entering commodity prices and the amount of money received from a customer by a keying operation; a note identifying device for identifying the denomination of the note received from the customer; an arithmetic control device adapted to add said commodity prices and to calculate the sum of said amount of money entered through said key input device and the amount of money identified by said note identifying device, said arithmetic control device being further adapted to compare the sum of said commodity prices and said sum of money with each other to calculate the amount of change; a display device adapted to display said sum of said commodity price, said sum of money received from the customer and said amount of said change; and a memory device adapted to memorize said sum of said commodity price, said sum of money received from the customer and said amount of said change. The note identifying device may include a device for detecting oblique orientation of the note. The note identifying device may further include a device for detecting the pattern of the note.

Register apparatus

A cover is provided on a note counter so that the cover provides a covering on a counting zone which is located on the top portion of the note counter and in which the number of a bundle of notes packed in a holder is counted. The cover is made of a transparent material for inspection and comprises two covering members which are driven so as to move in opposite directions.

There is provided a money exchanger apparatus comprising exchange rate input means adapted to enter exchange rates used when exchanging moneys or securities of a single country or plural countries other than a specific country into the currency of the specific country, numerical value information input means adapted to enter numerical information such as the amount and kind of moneys or securities to be exchanged, memory means for storing numerical value information, computing means for calculating the amount and kind of currency of the specific country from the numerical value information indicative of moneys or securities of the country other than the specific country, said information being delivered by the numerical information storing memory means, and from the exchange rate stored in said memory means, and disbursing means for paying out exchange money of the specific country based on the results of computations performed by the computing means.

Money exchanger apparatus

An apparatus for extraction of a desired number of sheets for use in a counting machine for paper sheets and the like, wherein paper sheets held in a stack between a holder and a paper-pressing bar are sucked and counted one at a time by respective suction heads provided on a rotational cylinder, a desired number of counted sheets on the side of the pressing bar being extracted from the machine by a separator which separates the counted sheets from the remaining sheets in a stack when the desired number of sheets have been counted. The apparatus for extracting a desired number of sheets comprises an operational mechanism incorporating a solenoid and associated members which is operated in cooperation with the action of said separator which separates the desired number of counted paper sheets from the remaining paper sheets so as to move said paper-pressing bar in a direction away from said holder and which can be reset to its original state. The associated members includes a link connecting the pressing bar for holding the paper sheets in cooperation with the holder with the solenoid, and a no paper sheet detecting device comprising an LED and a photosensor positioned so that it operates when the pressing bar is away from the holder and paper sheets are not present on the pressing bar.
