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 by the flow of turbine exhaust gas. Flow of the now-heated air continues into a second conduit in which it is guided toward the combustion chamber. Transition members are provided between the forward and rear headers, respectively, and the assembly for thermally isolating the assembly from the remainder of the gas turbine engine and for accommodating relative movement between the assembly and the forward and rear headers resulting from temperature differentials occurring during operation of the gas turbine engine.
