A suspension system (3) for an inner container (2, 2′) mounted for thermal insulation in an outer container (1, 1′) comprises a single fixed bearing (30, 31, 32, 33, 34, 35, 36, 37, 38, 39) comprising fixed bearing securing elements (5, 5′, 5″, 5′″) which engage, on the one hand, the outer container and, on the other hand, the inner container and which can be stressed in tension and in compression, the fixed bearing securing elements (5, 5′, 5″, 5′″) engaging while being arranged so as to be distributed in an annular installation space (7) defined between the inner container (2, 2′) and the outer container (1, 1′) and the fixed bearing securing elements (5, 5′, 5″, 5′″) engaging the outer container (1, 1′) while being distributed in the annular installation space (7). In addition, a floating bearing (41, 42, 43, 44, 45) arranged in the outer container (1, 1′) and supporting the inner container (2, 2′) and designed with a floating bearing ring (10, 10′) can be provided, with annularly distributed floating bearing securing elements (11, 11′), which can be stressed in tension and in compression, engaging, on the one hand, the floating bearing ring (10, 10′) and, on the other hand, the inner container or the outer container. The floating bearing ring (10, 10′) can be spring-biased by means of tension springs (12) or compression springs (13).

A LNG storage container includes: an inner shell made of a metal withstanding a low temperature of the LNG and configured to store the LNG inside; an outer shell made of a steel withstanding an internal pressure of the inner shell and configured to enclosing the outside of the inner shell such that a space is formed between the inner shell and the outer shell; and a heat insulation layer part installed in the space between the inner shell and the outer shell and configured to reduce a heat transfer.

The present invention is directed to a maritime vessel that uses a solid or semi-solid material to enclose substantially natural gas storage vessels in the hold of the vessel.
摘要:
Embodiments of the invention relate to support arrangements for semi-membrane tank walls and, more particularly, to a universal support assembly for tanks that experience thermal expansion and contraction. One embodiment of the invention may include a tank assembly having at least one tank wall, a support structure at least partially adjacent to the wall, and a link member coupling the tank to the support structure. The link member may be configured to accommodate relative movement between the tank and the support structure through rotation. The link member may be coupled to the tank wall by a ball and socket joint and coupled to the support structure with another ball and socket joint, allowing substantially unlimited in-plane movement of the tank wall relative to the support structure.

A cryogenic cooler is provided for use in craft such as launch, orbital and space vehicles subject to substantial vibration, changes in orientation and weightlessness. The cooler contains a small pore, large free volume, low density material to restrain a cryogen through surface tension effects during launch and zero-g operations and maintains instrumentation within the temperature range of 10.degree.-140.degree. K. The cooler operation is completely passive, with no inherent vibration or power requirements.
摘要:
A cryogenic storage tank with a built-in pump for pumping cryogen directly from the primary storage container consistent with low boil-off losses of cryogen has an outer vessel, an inner vessel and an evacuated insulation space therebetween. A pump mounting tube assembly extends into the interior of the inner vessel and includes an inner pump mounting tube and an outer pump mounting tube joined at their lower rims to define an insulating jacket between the two tubes. The inner pump mounting tube is affixed at its upper end to the outer vessel while the outer pump mounting tube is affixed at its upper end to the inner vessel. The inner pump mounting tube defines a relatively long heat path into the cryogenic container and is itself insulated from the liquid cryogen by a pocket of trapped gas formed within the inner pump mounting tube by heated cryogen. A pump may be introduced through the inner pump mounting tube and is also insulated against contact with liquid cryogen by the trapped gas such that only the lowermost end of the pump is immersed in cryogen thereby minimizing heat leakage into the tank.
摘要:
Heat barrier components and improved thermal insulation techniques are provided for an external tank insulation system of ships carrying liquefied natural gas, propane, ammonia, etc. Reduction of liquid boil-off rate or initial cost of insulation through the reduction of radiant heat leak is accomplished by a composite insulation system including a high reflectance component material on the external surface of insulation and/or interior surface of the ship facing the tank. Further, refrigeration in tank boil-off is used to cool a radiation shield located between the tank insulation and surrounding enclosure, and to cool the skirt support.
摘要:
A cryogenic fuel tank of a cylindrical design having toroidal surface ends, is suspended in aircraft structure through a central front mount member; and the rear tank is supported by rod elements which extend from a mounting ring about the tank, to mount points rearwardly within the interior of the fuselage. The central front mount member has baffles attached thereto, so as to prevent undue sloshing of the liquid within the tank. The front end of the tank suspension absorbs radial and axial loads, but no bending moments; and the aft linkage suspension arrangement takes primarily radical and torsional loads. Also the aft suspension provides for unrestrained axial and radial contraction and expansion of the outer shell of the tank.
