  • Publication number: 20200032676
    Abstract: A gas turbine plant is provided with a gas turbine, a heating device, a decomposition gas line, and a decomposition gas compressor. The heating device heats ammonia and thermally decomposes the ammonia to convert the ammonia into decomposition gas including hydrogen gas and nitrogen gas. The decomposition gas line sends the decomposition gas PG from the heating device to the gas turbine. The decomposition gas compressor increases the pressure of the decomposition gas to a pressure equal to or higher than a feed pressure at which the decomposition gas is allowed to be fed to the gas turbine.

  • Publication number: 20190063811
    Abstract: Provided are an ice making device and a method of inspecting the same. In the ice making device, signal lines extending from a temperature sensor are connected to a drive unit. The drive unit performs an ice removal process of removing ice from an ice making tray when a temperature detected by the temperature sensor is equal to or lower than a set temperature. The drive unit performs a sensor inspection process of automatically inspecting whether the temperature sensor is abnormal based on an inspection execution command issued by an operation of a test switch during general processes including supplying water to the ice making tray and an ice making process. Thus, inspection of a drive mechanism of the drive unit and inspection of the temperature sensor can be performed in a series of operations.

  • Patent number: 9631559
    Abstract: A fuel control method for a gas turbine with a combustor being formed of at least two groups of a pluralities of main nozzles for supplying fuel, and that supplies fuel from the main nozzles of all groups upon ignition of the combustor (S1), and supplies fuel from three main nozzles of a group A during subsequent acceleration of the gas turbine (S3). Because fuel is injected from a small number of the main nozzles during acceleration, the fuel flow rate per one main nozzle is increased, thereby increasing the fuel-air ratio (fuel flow rate/air flow rate) in a combustion region and improving the combustion characteristics. Accordingly, the generation of carbon monoxide and unburned hydrocarbon is reduced, whereby no bypass valve is required and manufacturing costs are reduced.
