Abstract
A gas turbine engine with an exhaust gas heat exchanger comprising a connection between the heat-exchanger outlet and an inlet of a combustion chamber for supplying heated compressed air to the combustion chamber, the connection including two pipes with a flexible element in the form of a metal bellows to compensate for thermal expansion. The pipes are symmetrically disposed and laterally spaced with respect to a line connecting the axis of the gas turbine to the axis of the heat exchanger outlet such that the metal bellows converge at an acute angle in the direction towards the heat exchanger. At one end the pipes are connected to the outlet of the heat exchanger by a pipe elbow and at their other ends to an inlet casing of the combustion chamber. In this way, differential temperature displacements are minimized.
