Title:
COLD HEAT UTILIZING GAS TURBIN POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/018579
Kind Code:
A1
Abstract:
A cold heat utilizing gas turbine power generation system 100 is provided with: an air liquefaction and separation device 10, a gas turbine power generator 20, a bottoming cycle 30, a pressurized oxygen supply line 52, and a pressurized nitrogen supply line 54. The air liquefaction and separation device 10 liquefies air Air by cold heat of liquid hydrogen LH2 to manufacture, in addition to a required amount of hydrogen gas H2, liquid oxygen LO2 and liquid nitrogen LN2. The gas turbine power generator 20 performs oxygen-enriched combustion of the hydrogen gas H2 to generate power. The bottoming cycle 30 has a reheat combustor 32 and a nitrogen cycle 40. The pressurized oxygen supply line 52 pressurizes the liquid oxygen LO2 in a liquid state, and supplies the pressurized liquid oxygen LO2 to the gas turbine combustor 24 as pressurized oxygen gas after heating the same with a nitrogen gas cooler 48. The pressurized nitrogen supply line 54 pressurizes the liquid nitrogen LN2 in a liquid state, and supplies the pressurized liquid nitrogen LN2 to an exit side of a nitrogen gas compressor 42 as pressurized nitrogen gas after heating the same with the nitrogen gas cooler 48.
