A first control valve system controls flow of the excess air flow along an excess air flow path to a supplemental gas turbine system. The excess air flow may be combusted with a fuel and supplied to the supplemental gas turbine system. 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 gas.

Abstract: A gas turbomachine includes a casing assembly surrounding a portion of the gas turbomachine. The casing assembly includes an inner casing portion defining a casing volume VC and a counter-flow cooling system arranged within the inner casing portion. The counter-flow cooling system includes a plurality of ducts that collectively define a channel volume Vch. The plurality of ducts is configured and disposed to guide cooling fluid through the casing assembly in a first axial direction and return cooling fluid through the casing assembly in a second axial direction that is opposite the first axial direction. The casing volume and the channel volume define a volume ratio of about 0.0002
