Abstract: A power generation system includes a gas turbine system including a turbine component, an integral compressor and a combustor to which air from the integral compressor and fuel are supplied, the combustor arranged to supply hot combustion gases to the turbine component, and the integral compressor having a flow capacity greater than an intake capacity of at least one of the combustor and the turbine component, creating an excess air flow. A first control valve system controls flow of the excess air flow along an excess air flow path to an exhaust of the turbine component. A selective catalytic reduction (SCR) unit may be coupled to an exhaust of the turbine component, the SCR unit receiving the exhaust and the excess air flow. An eductor may be positioned in the excess air flow path for using the excess air flow as a motive force to augment the excess air flow with additional air, creating an augmented excess air flow.
