ABSTRACT:
A system for preheating air before it enters the combustion chamber of a gas turbine engine includes a recuperator which extends between, and is supported by, forward and rear headers. Cold air to be pre-heated by the recuperator flows through an entry passage in the forward header, then into and through a first conduit of the recuperator which extends the length of the recuperator. The air then flows through a plurality of cross conduits located at different locations along the length of the recuperator where it becomes heated. Flow of the now-heated air continues into a second conduit in which it is guided toward the combustion chamber. Sleeves are provided, respectively, in the entry passage of the forward header and in the first conduit of the recuperator for maintaining substantially constant the pressure differential between the first and second conduits at all locations along the length of the recuperator.
