    Abstract: Apparatus for a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication, with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is then imposed on one or more tube support plates, as the steam generator heats up. The tube support plate displacement system has only one part, a push rod, which is internal to the steam generator shroud, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, in the same or varying amounts and directions, and with one or more apparatus for each individual tube support plate.

  • Patent number: 8708036
    Abstract: A heat exchanger for cooling high-temperature gas includes a gas tank portion into which the high-temperature gas is supplied through an inlet port of the gas tank portion, a plurality of tubes configured such that the high-temperature gas flowing from the gas tank portion passes therethrough, and a cooling-medium tank portion covering each of the tubes with a gap defined therebetween. Each of the tubes has an expansion portion located at a side of the inlet port. A cooling medium flows in the gap on an outer peripheral surface of the tube. The gas tank portion, the cooling-medium tank portion, and the expansion portion of the tube are stacked such that a partition portion between the gas tank portion and the cooling-medium tank portion has a thickness larger than a thickness of the gas tank portion or the cooling-medium tank portion.

  • Patent number: 8695688
    Abstract: A self-supporting system for positioning and restraining the U-bend tubes in the U-bend region of a nuclear steam generator includes arrays incorporating unique support bars having nubs projecting in the out-of-plane direction of the tube planes. The system also includes assemblies for spacing the arrays, tie bars to prevent the arrays from splaying and saddle bar assemblies to support the outermost tube layers. The system provides positive restraint to nub engaged tubes in both the in-plane direction of the tube planes and the out-of-plane direction.

  • Publication number: 20140060787
    Abstract: Apparatus for a steam generator that employs tube support plates within a shroud that is in turn disposed within a shell. The tube support plates are made of a material having a coefficient of thermal expansion lower than that of the shroud. The tube support plates are aligned during fabrication, with minimal clearances between components. Using a tube support displacement system, a controlled misalignment is then imposed on one or more tube support plates, as the steam generator heats up. The tube support plate displacement system has only one part, a push rod, which is internal to the steam generator shroud, thereby minimizing the potential of loose parts. The tube support plate displacement system can be used to provide controlled misalignments on one or more tube support plates, in the same or varying amounts and directions, and with one or more apparatus for each individual tube support plate.

    Abstract: The present invention relates to a device for reducing the vibrations of a tube bundle of a heat exchanger inside its shell, wherein this device allows a secure and quick insertion after the bundle has been manufactured. This easy insertion after manufacturing the bundle allows the high temperatures to which the bundle is subjected for the attachment by means of brazing to not affect the properties of the device, particularly the elasticity achieved by means of tempering, for example.
