Abstract
A primary surface recuperator is made from a plurality of components, one of such components being a primary surface sheets. The primary surface sheet is used to transfers heat from a donor fluid to a recipient fluid. A first sheet portion of the primary surface sheet has a pair of sides and has a preestablished thermal deformation characteristic including a resistance to high temperature deformation and a high temperature resistance to corrosion. A second sheet portion has a pair of sides and has a preestablished thermal deformation characteristic being less than the resistance to high temperature deformation and the high temperature resistance to corrosion of the first sheet portion. The first sheet and the second sheet are attached at a respective one of the pair of sides of the first sheet portion and the second sheet portion forming an axis. The axis is positioned at an angle to the pair of sides.
