Title
(EN) GAS TURBINE POWER AUGMENTATION METHOD
(FR) PROCEDE D'AUGMENTATION DE PUISSANCE D'UNE TURBINE A GAZ
Abstract
(EN)
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).
(FR)
L'invention concerne un procédé d'augmentation de puissance d'une turbine à gaz (1), procédé dans lequel de l'eau est injectée dans un ou plusieurs étages (22, 24, 26, 28) d'un compresseur auxiliaire (2) afin de produire un courant gazeux (20) contenant de la vapeur. Ce courant gazeux contenant de la vapeur (20) est introduit, au moins en partie, dans des chambres de combustion (16) de la turbine à gaz (1), en vue d'augmenter la puissance. Une partie du courant gazeux comprimé contenant de la vapeur (20) peut être introduite dans un réacteur (84) pour générer un gaz de synthèse contenant de l'hydrogène (90), de manière à supporter des températures de flamme inférieures, se produisant dans les chambres de combustion (16) de la turbine à gaz (1), du fait de l'introduction du courant gazeux contenant de la vapeur (20). De cette façon, des émissions de NOx de la turbine à gaz (1) peuvent être réduites. En outre, le procédé d'augmentation de puissance peut être mis en oeuvre conjointement avec un cycle combiné de gazéification intégrée (124).
