A power generation system 100 may include a generator 122, 166, and a gas turbine system 102 for powering the generator 122, 166, the gas turbine system 102 including a turbine component 104, an integral compressor 106 and a combustor 108 to which air from the integral compressor 106 and fuel are supplied, the combustor 108 arranged to supply hot combustion gases to the turbine component 104, and the integral compressor 106 having a flow capacity greater than an intake capacity of at least one of the combustor 108 and the turbine component 104, creating an excess air flow 200. A turbo-expander 272 may also power the generator 122, 166. A first control valve 262 to control flow of the excess air flow 200 along an excess air flow path 250 to an inlet of the turbo-expander 272. An educator may be positioned in the excess air flow path 250 for using the excess air flow 200 as a motive force to augment the excess air flow 200 with additional air 254. A discharge 274 of the turbo-expander 272 is supplied to an exhaust 172 of the turbine component 104 for an HRSG. |
