Abstract
A method and apparatus for power augmentation in gas turbine cycles is provided that efficiently provides at least air and preferably both steam and air injection. In an embodiment of the invention, an air injection compressor is driven with steam used for gas turbine injection prior to its injection into the gas turbine. In addition to power output, the thermodynamic efficiency is improved in simple cycle turbine power plants with the disclosed method and apparatus.
