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. Upon arrival at the job site in the field, a crane lifts the heat exchanger receiver to vertical, rotating about the trunnion shafts on the fixture, and then lifts the heat exchanger receiver for placement at a desired location.

A sealing apparatus adapted for use in a pressure vessel such as a synthesis gas cooler. The sealing apparatus is of a segmented plate construction formed around an outer wall section of a conduit means of the pressure vessel that defines at least part of a passage for receiving effluent from a gasification process. Pressure responsive mechanisms are provided on the plate segments to maintain the pressure difference across the sealing apparatus within the acceptable operating limits as well as to permit instantaneous pressure release to prevent damage to the pressure part assembly or cage. The seal is also maintained continuously through the differential growth movement between the conduit means and the pressure vessel during heat up and cool down cycles.

A method and apparatus particularly suited to the manufacture and assembly of cage-like, substantially cylindrical structures made of long, slender tubular components which, by themselves, are not self-supporting, employs an exo-skeleton structure to assemble cage-like, tubular structures in pie-shaped, longitudinal segments while in a horizontal or vertical position utilizing longitudinal or circumferential attachments. The apparatus comprises at least two segments which permit construction of subassemblies of the cage-like, tubular structure and their transportation, if necessary, to a remote site where they may be finally assembled.
