A cooling system for a combustion turbine transition section. The combustion turbine includes a compressor assembly with a compressed air bleed line, a combustor assembly, a transition section with integral cooling channels, a turbine assembly with integral cooling channels. The compressor assembly is coupled to the combustor assembly, the combustor assembly is further coupled to the transition section, the transition section is further coupled to the turbine assembly. The compressor assembly, combustor assembly, transition section, and turbine assembly form a flow path. The cooling device includes a compressed air steam generator, a feed water source coupled to, and providing water to, the compressed air steam generator, a steam pipe coupled to the transition section cooling channels and the compressed air steam generator. The compressed air bleed line passes through the compressed air steam generator. In operation, the compressor compresses the ambient air thereby raising the ambient air temperature. The majority of the compressed air flows into the combustor assembly where it is mixed with a fuel and ignited. A portion of the hot compressed air is directed to the compressed air steam generator and converts water in the compressed air steam generator into steam. The steam passes through the steam pipe into the transition section cooling channels, thereby cooling the transition section.
