“…2. A description on the working principles of the evaluated PAT systems have been discussed in the published literature [3,[8][9][10][11][12][13]; therefore, no effort is made here to repeat such information in this paper. However, assumptions made to conduct thermodynamic performance and economic analysis for considered PAT systems are discussed and summarized in the next section.…”

“…The introduced steam mass now can be in the range of 3-10% of the inlet air mass flow rate [10,12]. The maximum amount of injected steam is dependent on a specific CT and is limited by factors such as compressor surge margin, CT shaft loading, and generator overload capability.…”

There exists a widespread interest in the application of gas turbine power augmentation technologies in both electric power generation and mechanical drive markets, attributable to deregulation in the power generation sector, significant loss in power generation capacity combined with increased electric rates during peak demand period, and need for a proper selection of the gas turbine in a given application. In this study, detailed thermo-economic analyses of various power augmentation technologies, implemented on a selected gas turbine, have been performed to identify the best techno-economic solution depending on the selected climatic conditions. The presented results show that various power augmentation technologies examined have different payback periods. Such a techno-economic analysis is necessary for proper selection of a power augmentation technology.

“…This steam is injected in the combustion chamber of the gas turbine, resulting in an efficiency gain and a power augmentation. Rice [2] developed a steam injected gas turbine cycle with a topping in which a HP steam is first expanded in a back-pressure steam turbine, producing power, and then is injected into the combustion chamber of the gas turbine. Borat [3] found that the efficiency and the net output of the gas turbine increased considerably, of the order of 20-40 percent with the steam injection.…”

“…All of them offer increased performance and increased output compared to a dry gas turbine cycle. Several types of water or steam injection gas turbine cycle (STIG) have been proposed in previous studies and the performance characteristics of them investigated [1,[4][5][6][7][8][9][10][11][12][13][14]. The exhaust gas from the turbine is used as an energy source in a heat recovery steam generator (HRSG) where energy is transferred from the exhaust gases to the boiler feed water.…”

Résumé -Amélioration des performances des turbines à gaz utilisées dans les conditions sahariennes par injection de vapeur d'eau -Le rôle des turbines à gaz, dans la production d'électricité et l'industrie pétrolière, a pris une dimension particulière ces dernières années. À cet effet différentes méthodes (régénération, refroidissement intermédiaire, préchauffage et injection de vapeur d'eau) ont été utilisées afin d'améliorer les performances des cycles de turbine à gaz. Dans cette optique, la méthode d'injection de vapeur d'eau en amont de la chambre de combustion d'une turbine à gaz a été proposée, étudiée et comparée avec un cycle simple. L'objectif principal de ce travail consiste en l'élaboration d'un programme de calcul de l'influence des conditions ambiantes sur les caractéristiques des différents processus de la turbine à gaz, telles que la compression, la combustion et la détente. Une fois les paramètres de fonctionnement optimaux connus, le calcul des performances de l'installation a été revu en injectant des quantités convenables de vapeur d'eau en amont de la chambre de combustion. Les résultats obtenus sont en accord avec ceux de la littérature et montrent que la méthode d'injection de vapeur d'eau en amont de la chambre de combustion améliore considérablement les performances de la turbine à gaz. Ces résultats sont représentés sous forme de courbes en deux et trois dimensions pour une meilleure illustration des phénomènes physiques. Abstract -Gas Turbine Performances Improvement using Steam Injection in the Combustion Chamber under Sahara Conditions -Gas turbines are generally used for large scale power generation. The basic gas turbine cycle has low thermal efficiency which decreases in the hard climatic conditions of operation, so it is important to look for improved gas turbine based cycles. Among several methods shown their success in increasing the performances, the steam injected gas turbine cycle (STIG) consists to introduce a high amount of steam at various points in the cycle. The objective of the present work is to improve the performances of gas turbine used under
