A raw material gas liquefying device includes a feed line; a refrigerant circulation line; and a controller. In a refrigerant liquefaction route, a refrigerant flows through a compressor, a heat exchanger, a circulation system JT valve, a liquefied refrigerant storage tank, and the heat exchanger, and returns to the compressor. In a cryogenic energy generation route, the refrigerant flows through the compressor, the heat exchanger, an expansion unit, and the heat exchanger, and returns to the compressor. The controller determines if a refrigerant storage tank liquid level is within an allowable range, manipulates a feed system JT valve opening rate to control refrigerant temperature at the high-temperature-side refrigerant flow path exit side of the heat exchanger, and manipulates the opening rate of the feed system JT valve to control the refrigerant storage tank liquid level so that the refrigerant storage tank liquid level falls into the predetermined allowable range.

A sealing structure for sealing a gap between a combustor liner having an outer surface and a surrounding structure surrounding the combustor liner, includes: an annular sealing member held on the surrounding structure so as to be in contact with the outer surface of the combustor liner. The sealing member includes a plurality of sealing segments arranged in an annular configuration. The sealing structure seals the gap around the combustor liner of the combustor and absorbs, the difference in thermal expansion between the combustor liner and the surrounding structure.

Sealing structure for combustor liner

A seal structure for sealing a gap between a combustor liner and a neighboring structure adjacent to the combustor liner, includes an annular sealing member mounted on the neighboring structure so as to be in contact with an annular outer surface of the combustor liner to seal the gap between the combustor liner and the neighboring structure. The annular sealing member includes a plurality of sealing segments which are arranged in an annular form as a whole.

The liner supporting structure for the annular combustor of the present invention has a flexible connection member of connecting a structural body constituting a part of the combustor to a liner, the connection member having a first end positioned on a side of the structural body and a second end positioned on a side of the liner, the second end being disposed on an outer surface of an end part of the liner positioned on the side of the structural body; a first fixing means of fixing the first end of the connection member to the structural body; and a second fixing means of fixing the second end of the connection member to the end part of the liner. According to the present invention, even in the case that there is a large difference in linear expansion coefficient between the materials of the liner and the structural body of the combustor for supporting the liner so that a relative displacement is generated between the two due to temperature changes, the structural body of the combustor can strongly support the liner without applying excessive stress to the liner formed by, for example, a ceramics material.
