Abstract: The present invention is a combustion turbine assembly connected to a steam generator which utilizes deaerated potable water. The steam formed by the steam generator may be combined with air and injected into the combustor of the combustion turbine assembly to increase the mass flow of gas through the turbine for power augmentation. The deaeration of the feed water to the steam generator eliminates the need to demineralize the water and eliminates the use of more costly alloys for heat exchanger components of a steam generator.
