A gas turbine is provided in which heat is removed from compressed air bled from the compressor section, for purposes of cooling in the turbine section, using a first heat exchanger to transfer heat from the cooling air to an intermediate fluid. The heat so removed is then returned to the cycle by transferring it from the intermediate fluid to a fluid to be injected into the combustion section, such as gaseous fuel or water for NOx control, using a second heat exchanger. A third heat exchanger may be used in conjunction with the second heat exchanger to control the temperature of the intermediate fluid and, hence, the temperature of the cooling air.
