摘要:
An energy supply system, which is a system constituting a regional power system in a target region, includes a power transmission system including a first power generation facility and a second power generation facility, a power transmission and distribution system that supplies power to each consumer, a management system, and an unmanned flying object. The unmanned flying object has a transport function of transporting a cargo and a power supply function of supplying power to an outside. When the amount of power supplied by the power transmission system is less than the amount of power required by the power transmission and distribution system, the management system performs a power adjustment process of supplying power from the unmanned flying object to the power transmission and distribution system by using the power supply function of the unmanned flying object.

A hydrogen/oxygen stoichiometric combustion turbine system includes: a high-pressure steam turbine (2); a low-pressure steam turbine (3); and a heater (5) disposed between the high-pressure and low-pressure steam turbines. The heater (5) has a combustion portion (53) in which stoichiometric combustion of hydrogen and oxygen is caused, and a mixing portion (55) configured to mix discharged steam (S4) from the high-pressure steam turbine (2) with combustion gas (R) from the combustion portion (53) and to supply the obtained product to the low-pressure steam turbine (3).

An exhaust diffuser includes: a plurality of struts, each of which penetrates an internal cylinder and an external cylinder and couples a bearing support and a structural body together, the bearing support disposed inside the internal cylinder, the structural body disposed outside the external cylinder, each strut inclined rearward from the bearing support toward the structural body; and a plurality of strut covers that surround the plurality of struts, respectively, between the internal cylinder and the external cylinder. The external cylinder includes a tapered first stepped portion that expands a diameter of the external cylinder and that overlaps leading edges of the plurality of strut covers in an axial direction of the external cylinder. The internal cylinder includes a tapered second stepped portion that expands a diameter of the internal cylinder and that overlaps trailing edges of the plurality of strut covers in an axial direction of the internal cylinder.

An intake structure of a compressor includes an intake duct forming an intake port opening in a direction away from a central axis of the compressor and a bellmouth forming an annular channel expanding from an inlet of the compressor toward an inner space of the intake duct. The bellmouth includes a plurality of struts connecting an inner casing positioned inside the annular channel and an outer casing positioned outside the annular channel. At least one of a plurality of transverse struts, of the plurality of struts, which are located on both sides of a center plane passing through the central axis of the compressor and the center of the intake port has a trailing edge positioned on a virtual plane passing through the central axis of the compressor and a leading edge positioned on a side of the intake port with respect to the virtual plane.

A turbine ventilation structure includes: an exhaust diffuser including inner and outer tubes to form an exhaust passage for exhaust gas; a strut extending across the exhaust diffuser from a housing to support a bearing inside the inner tube; a strut cover in the exhaust passage that covers the strut; and a connecting member disposed downstream of the strut cover and including a hollow portion to connect the housing and the inner tube. The housing includes a first intake port to introduce an air from outside. The strut cover has a discharge hole at a rear edge portion thereof. The turbine ventilation structure includes a first ventilation passage extending from the first intake port through the hollow portion, then extending from an inner end portion of the strut through between the strut and the strut cover, and the discharge hole, into the exhaust passage.
摘要:
A heat storage mechanism, of a heat exchanger, which does not shorten the service life of the heat exchanger even when a facility using the heat exchanger is intermittently operated and which suppresses a decrease in efficiency at the time of restart of the facility, is provided. The heat storage mechanism for storing heat of a heat exchanger during stop of operation of a facility provided with the heat exchanger includes an outflow prevention unit configured to prevent outflow of an exhaust gas to the outside, which is a heating medium of the heat exchanger, during stop of operation of the facility is provided in an exhaust passage through which the exhaust gas is discharged to the outside.
