GAS TURBINE POWER AUGMENTATION METHOD

摘要

A power augmentation method for a gas turbine (1) in which water is injected into one or more stages (22, 24, 26, 28) of an auxiliary compressor (2) to produce a vapor containing gas stream (20). The vapor containing gas stream (20) is at least in part introduced into combustors (16) of the gas turbine (1) for power augmentation. Part of the vapor containing compressed gas stream (20) can be introduced into a reactor (84) to generate a hydrogen containing synthesis gas (90) to support lower flame temperatures occurring within the combustors (16) of the gas turbine (1) due to the introduction of the vapor containing gas stream (20). In such manner, NOx emissions of the gas turbine (1) can be reduced. Furthermore, the power augmentation method can be conducted in conjunction with an integrated gasification combined cycle (124).
