A turbo cluster gas turbine system includes: at least one combustor configured to combust a fuel to generate a combustion gas; an output turbine configured to be driven with the combustion gas from the at least one combustor; and a plurality of supercharging systems configured to supply compressed air to be supplied to the at least one combustor, wherein each of the supercharging systems includes: a first turbocharger having a rotation shaft formed separately from a rotation shaft of the output turbine and configured to be driven with the combustion gas from the combustor; a first air line for supplying compressed air compressed by a compressor of the first turbocharger to the combustor; and a first combustion gas line for supplying the combustion gas from the combustor to a turbine of the first turbocharger.

Turbo cluster gas turbine system and activation method thereof

A storage tankA has a heat insulating material layerformed on the outer side of a partition wallthat has a container shape. The inside of the storage tankA is divided into two storage spaces V, V. The first storage space Vstores liquefied hydrogen LHand the second storage space Vstoring slush hydrogen SH. A plurality of finsare disposed on the partition plateso as to promote heat transfer between the liquefied hydrogen LHand the slush hydrogen SHand to reduce the amount of evaporation gas from the liquefied hydrogen LH. An escape pipeis connected to the storage space V, and the fuel supply pipesare connected to the storage spaces V, V, respectively. The fuel supply pipesare connected to a combustorvia the main fuel pipe
