Abstract
A method for operating a gas turbine engine, including a first compressor, a second compressor, a combustor and a turbine, coupled together in serial flow arrangement, and an intercooler coupled between the first compressor and the second compressor, the intercooler including a first heat exchanger and a second heat exchanger. The method includes channeling compressed airflow from the first compressor to the first heat exchanger, extracting energy from the compressed airflow using a first working fluid flowing through the first heat exchanger to facilitate reducing an operating temperature of the compressed airflow and to facilitate increasing an operating temperature of the first working fluid, and channeling the first working fluid to a process heat exchanger, and channel the compressed airflow form the first heat exchanger to the second compressor.
