SYSTEM AND METHOD OF RECIRCULATING EXHAUST GAS FOR USE IN A PLURALITY OF FLOW PATHS IN A GAS TURBINE ENGINE

摘要

A method includes generating an exhaust gas from combustion gases with a turbine; recirculating the exhaust gas along an exhaust recirculation flow path; reducing moisture within the exhaust gas along the exhaust recirculation path with an exhaust gas processing system; providing the exhaust gas to a first exhaust gas inlet of an exhaust gas compressor for compression; and providing the exhaust gas from the exhaust recirculation path to a second exhaust gas inlet separate from the first exhaust gas inlet for cooling, preheating, sealing, or any combination thereof.

1. A system, comprising:
a gas turbine system, comprising:
a turbine combustor;a turbine driven by combustion products from the turbine combustor; andan exhaust gas compressor driven by the turbine, wherein the exhaust gas compressor is configured to compress and supply an exhaust gas to the turbine combustor;an exhaust gas recirculation (EGR) system, wherein the EGR system is configured to recirculate the exhaust gas along one or more exhaust recirculation paths from the turbine to first and second exhaust gas inlets of the gas turbine system, and the exhaust recirculation system comprises a scrubbing system and a moisture separator upstream of at least the second exhaust gas inlet; and wherein the first exhaust gas inlet enables the exhaust gas compressor to intake the exhaust gas for exhaust gas compression, and the second exhaust gas inlet is separate from the first exhaust gas inlet.
