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.

Abstract: A self-cleaning filter system is disclosed that includes an inlet fitting that is adapted to be inserted into an existing filter body. A spray tube having a plurality of outlets that slideably engages the inlet fitting, is positioned in the ring discs of the existing filter and a compression member proximate to one end of the ring discs applies a compressive force to the ring discs. When fluid enters the spray tube from the inlet fitting compression on the ring discs is reduced to allow the ring discs to separate while fluid pressure is simultaneously imposed on the ring discs through a plurality of outlets to clean the filter component. The parts included with the system may be used to convert a manual filter into a self-cleaning filter system.
