  • Publication number: 20240068416
    Abstract: This gas turbine equipment comprises a gas turbine and a control device. A combustor of the gas turbine uses ammonia as fuel, and uses the RQL method. A compressor of the gas turbine includes an intake adjustor that adjusts an intake rate which is the flow rate of air that flows into a compressor casing. When the concentration of NOx in exhaust gas reaches or exceeds a predetermined value, the control device controls the operation of the intake adjustor so that the intake rate decreases.

  • Patent number: 8250327
    Abstract: In a storage apparatus and its control method including multiple first virtual volumes to be provided to a host system and multiple pools each having a memory capacity, and equipped with a function of dynamically allocating a storage area to the first virtual volumes from the pools associated with the first virtual volumes in accordance with the usage status of the first virtual volumes, the unused capacity in each of the pools is managed, and, when the unused capacity of one of the pools falls below a predetermined threshold value, a part of the unused capacity of the other pools is allocated to the one pool. It is thereby possible to realize a highly reliable storage apparatus and its control method.
