Abstract:
1. A method for improved emissions performance of a gas turbine having a compressor section, a combustor, a turbine section and a fuel supply system, the method comprising: a. flowing an exhaust gas from the turbine section through a condensation collection system; b. condensing water vapor from the exhaust gas via the condensation collection system to provide a de-moisturized exhaust gas downstream from the condensation collection system; c. progressively compressing the de-moisturized exhaust gas via an axial flow compressor; d. flowing the compressed de-moisturized exhaust gas and the condensed water vapor to a mixing chamber; e. remixing the condensed water vapor and the compressed de-moisturized exhaust gas to produce a re-moisturized exhaust gas; and f. flowing the re-moisturized exhaust gas to at least one of the fuel supply system, the compressor section or the combustor of the gas turbine.
