Abstract
A power plant is provided which includes a gas turbine having a compressor for producing compressed air and a combustor for combusting the compressed air with a combustible fuel to produce a heated combustion gas. The power plant also includes a heat recovery steam generator for generating a flow of steam from an exhaust of the gas turbine and a steam turbine for expanding the flow of steam from the heat recovery steam generator. The steam turbine has a rotor having a rotor bore disposed axially therein. The power plant also includes a conduit for directing at least a portion of the compressed air or at least a portion of the heated combustion gas from the gas turbine to the rotor bore of the steam turbine, wherein the compressed air or the heated combustion gas may warm the rotor bore of the steam turbine.
