ABSTRACT:
A gas turbine plant in which the drive line of a power turbine extends substantially parallel to the longitudinal axis of the gas generator, the compressor drive turbine and power turbine being traversed in opposite directions by heated exhaust gases from a combustion chamber. A heat exchanger receives exhaust gases from the power turbine to heat compressed air to be delivered to the combustion chamber. The heat exchanger includes a matrix of U-shaped tubes connected to supply and discharge ducts of compressed air. The entire tube matrix is enclosed within an exhaust gas collector housing mounted downstream of the exhaust gas outlet of the power turbine and extending along the combustion chamber. The ducts are arranged in substantially parallel, adjacent relation and are each closed at one end. The open ends of the supply ducts respectively communicate with an outer channel of the plant which terminates at an end of the combustion chamber to receive compressed air to be heated. The open end of the discharge ducts connects directly into the combustion chamber.
