A recuperator core has a plurality of passages sealingly formed therein. In use, a fluid passes through a respective one of the plurality of passages under pressure. The recuperator core must be tested to determine an operational efficiency or leakage within the respective plurality of passages. A pair of sealing mechanisms are positioned at a respective one a pair of ends of the respective one of the plurality of passages. A pressure or a vacuum is pulled across the respective ones of plurality of passages and a rate of leakage or decay rate is monitored to define an operational recuperator core and a failed recuperator core.

Apparatus and method for testing a recuperator core for leakage

A system is disclosed to manufacture a recuperator core. The core is made up of a plurality of cells and an inner sealing member. A manufacturing system has an input end, an assembly station having a lower or inner chucking portion and an upper portion, and a welding station. The lower or inner chucking portion is movable between a lower position and an upper position and has a retracted position and an expanded position. The upper portion is movable between a loading position and a clamping position and is rotatable between a first position and a second position. The welding station performs a tack welding operation and a lineal welding operation.

System for manufacturing a circular primary surface recuperator

An assembly line for economically and efficiently assembling a core into a recuperator. The assembly line has an inlet end, an assembly station, a welding station, a control station and an outlet end. The inlet end has a plurality of the cores to be used for assembly thereat. The core is positioned within the assembly station and an assembly fixture locates a ducting structure in a preestablished relationship to the core. The control station using a plurality of sensors sends an input to a controller and the welding station performs a weld fixedly securing the ducting structure to the core.
