Abstract:
PROBLEM TO BE SOLVED: To provide a storage tank for liquefied fuel which further reduces the amount of evaporated gas of stored low-temperature liquefied fuel while suppressing increase of volume and weight of a storage tank.SOLUTION: A storage tank 10A has a heat insulation material layer 14 formed on the outside of a barrier wall 12 of a container shape. The interior of the storage tank 10A is partitioned into two storage spaces V, Vby a parting plate 16, liquefied hydrogen LHis stored in a storage space Vand slush hydrogen SHis stored in a storage space V. A number of fins 18 are disposed on the parting plate 16, facilitate heat exchange between liquefied hydrogen LHand slush hydrogen SH, and reduce the amount of evaporated gas of liquefied hydrogen LH. A vent pipe 20 is connected to the storage space Vand fuel supply pipes 24a, 24b are respectively connected to the storage spaces V, V. Fuel supply pipes 24a, 24b are connected to a combustor 26 via a fuel main pipe 24.
Abstract:
A storage tank 10A has a heat insulating material layer 14 formed on the outer side of a partition wall 12 that has a container shape. The inside of the storage tank 10A is divided into two storage spaces V1, V2. The first storage space V1 stores liquefied hydrogen LH2 and the second storage space V2 storing slush hydrogen SH2. A plurality of fins 18 are disposed on the partition plate 16 so as to promote heat transfer between the liquefied hydrogen LH2 and the slush hydrogen SH2 and to reduce the amount of evaporation gas from the liquefied hydrogen LH2. An escape pipe 20 is connected to the storage space V1, and the fuel supply pipes 24a, 24b are connected to the storage spaces V1, V2, respectively. The fuel supply pipes 24a, 24b are connected to a combustor 26 via the main fuel pipe 24.
Abstract:
Device for storing and releasing fluids at nearly constant pressure, the fluids including a gas and a liquid, includes an assembly of substantially identical reservoirs (1), where the reservoirs include: a portion containing the gas (G) and a portion containing the liquid (L), an element (23) of separation between the gas and the liquid in the reservoir (1), an inlet orifice (36) and an outlet orifice (36) for the gas, an inlet orifice (35) and an outlet orifice (35) for the liquid. The reservoirs (1) have a cylindrical outer envelope (100) made up of at least one metal tube (101) of the type of those used for gas pipelines and oil pipelines, for which: the external diameter is more than 32 inches (813 mm); and the ratio of the length thereof to the outer diameter thereof is greater than 8.
