Title:
CRYOGENIC POWER GENERATING FACILITY
Document Type and Number:
Japanese Patent JP3924800
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To resolve the problem that an intermediate medium is leaked and increase the recovery efficiency of the cold energy of a low-temperature fluid by installing a gas turbine constituted of a compressor and a turbine in a circular closed loop duct, and providing a low-temperature fluid feed pipe and a turbine inlet pipe on the outside of the closed loop duct.
SOLUTION: A closed loop duct 2 formed into a circular shape with steel or concrete and capable of sealing an intermediate medium 1 having low reactivity such as air or nitrogen in it is prepared, and a gas turbine provided with a compressor 3 and a turbine 4 on the same shaft and a power generator 5 are installed in it. A cooler 6 is arranged at the inlet section of the compressor 3, and a regenerative heat exchanger 7 is arranged at the outlet of the turbine 4 in the closed loop duct 2. The intermediate medium 1 from the regenerative heat exchanger 7 is heated by a heater 11 provided on the outside, then it is fed to the inlet of the turbine 4 by a turbine inlet pipe 12 provided through the closed loop duct 2. A medium storage tank 15 is connected via pipes 13 on the outside of the closed loop duct 2.
