  • Patent number: 9194609
    Abstract: A shop-assembled solar receiver heat exchanger having an arrangement of heat transfer surfaces and a vertical steam/water separator structurally and fluidically interconnected thereto. A vertical support structure is provided to support the vertical separator and the heat transfer surfaces. The vertical support structure is bottom supported, while the vertical steam/water separator and heat exchanger heat transfer surfaces are top supported from the vertical support structure. The vertical support structure provides structural support and rigidity for the heat exchanger and a means by which the heat exchanger can be picked up and lifted for placement at a desired location. A fabrication/transport/lifting fixture is provided which facilitates fabrication, assembly, transportation and erection of the heat exchanger from the shop to the field. The fixture supports two trunnion shafts attached to the support structure of the receiver. Lifting lugs would be located on the top end of the support structure.

  • Publication number: 20090178779
    Abstract: A heat exchanger having an arrangement of heat transfer surfaces and a pair of vertical steam/water separators structurally interconnected to one another to provide an integral support structure for the heat exchanger. The structural interconnection includes upper and lower structural members extending between the pair of vertical steam/water separators. The upper and lower structural members include headers, and an arrangement of heating surface which extends between and is fluidically connected to the headers. A structural support framework surrounds the heat exchanger for bottom support thereof, the framework providing structural support and rigidity for the heat exchanger and a means by which the heat exchanger can be picked up and lifted for placement at a desired location.
