Abstract

A power augmentation method for a gas turbine in which water is injected into one or more stages of an auxiliary compressor to produce a vapor containing gas stream. The vapor containing gas stream is at least in part introduced into combustors of the gas turbine for power augmentation. Part of the vapor containing compressed gas stream can be introduced into a reactor to generate a hydrogen containing synthesis gas to support lower flame temperatures occurring within the combustors of the gas turbine due to the introduction of the vapor containing gas stream. In such manner, NOx emissions of the gas turbine can be reduced. Furthermore, the power augmentation method can be conducted in conjunction with an integrated gasification combined cycle.
