“…The design point polytropic (adiabatic) efficiency is taken as 73%, which is congruent with the micro turbine size [1][2][3][4]36,37]. The turbine polytropic adiabatic efficiency is set to 80% and a combustion chamber adiabatic efficiency of 98% is assumed.…”

“…When designed for a power output of 5 to 15 kW, micro turbines are of interest for various commercial and military applications [1,[4][5][6][7][8]. They could provide the power for a household or a small set of units [1,4,6,9], or form the backbone of a distributed backup and peak demand system as they offer an unparalleled flexibility [1][2][3]6,[10][11][12][13].…”

“…Turbomachinery efficiencies are, for instance, affected by the small blade height, low Reynolds numbers, tip clearance effects, and surface finish [1,3,10,15]. At the considered power level, manufacturing limitations become significant and heat transfer and fluid leaks start to dominate [1,3,4,9,10]. Components that are in close proximity can operate at significantly different temperatures, resulting in heat fluxes of the same magnitude as the energy involved in compression and expansion [16].…”

“…Miniature or micro gas turbines are small, single-stage, low pressure ratio, gas turbine engines that typically employ radial compressor and turbine rotors [1][2][3][4][5]. When designed for a power output of 5 to 15 kW, micro turbines are of interest for various commercial and military applications [1,[4][5][6][7][8].…”

Résumé -Optimisation des systèmes de turbine à combustion en cogénération pour différentes configurations des échangeurs de chaleur -Cet article explore et compare les performances des trois configurations de systèmes de turbine à combustion permettant la production combinée de chaleur et d'électricité, sur la base du cycle irréversible régénératif de Brayton-Joule. Le modèle proposé est développé pour deux contraintes différentes sur le cycle, notamment le flux de chaleur produit par combustion imposé ou la température maximale du cycle imposée. Le modèle considère également l'irréversibilité due au frottement dans le compresseur et la turbine et celle due aux pertes de chaleur dans la chambre de combustion et les échangeurs de chaleur. Le rendement au sens du premier principe du système sans et avec cogénération et le rendement exergétique rendent compte des avantages de la cogénération, et aident le concepteur à choisir la meilleure configuration de turbines à combustion en fonction de ses besoins. Des données expérimentales d'une microturbine opérationnelle ont été utilisées pour valider le modèle. La puissance fournie et les rendements au sens du premier principe et exergétique sont optimisés par rapport à un ensemble de paramètres de fonctionnement. Les valeurs optimales des paramètres du moteur à turbine à combustion qui correspondent au maximum de puissance fournie, respectivement au maximum de rendement thermodynamique sont discutées. Les résultats montrent que la plupart des performances maximales correspondent aux mêmes valeurs optimales du taux de compression pour le flux imposé, sauf le rendement exergétique maximum qui demande des valeurs plus élevées du taux de compression que celles pour le maximum du flux d'exergie. Une comparaison des performances de ces trois configurations et les perspectives sont proposées. Abstract -Optimization of Gas Turbine Cogeneration System for Various Heat Exchanger

This article refers to a Molten Carbonate Fuel Cell (MCFC) system coupled to a plant with a microgas turbine and a heat recovery system for obtaining a small sized hybrid system in co‐generative arrangement.MCFC are devices capable of concentrating carbon dioxide (CO2) produced in anode exhaust gases. If they are handled conveniently, it is possible to separate and store the surplus CO2 produced by the plant instead of emitting it into the atmosphere.From the simulation model of the MCFC system, previously developed by the authors, a zero‐dimensional and stationary simulation model for the whole hybrid system was formulated and implemented in the same language.By the simulation model of the MCFC system it has been possible to make a parametric analysis of the hybrid plant to find some optimal operating conditions of the fuel cell(s) that maximise the performance of the entire hybrid plant. In addition, the separation of the CO2 surplus produced by the hybrid plant was simulated by the model and then the emissions of carbon monoxide (CO) and nitrogen oxides (NOx) from the same plant were evaluated.
