“…Ghazi et al [8] carried out the parametric analysis of exergy unit price ($/kW h) depending on the design parameters, such as high and low drum pressures, steam mass flow rate, PP temperature with and without DB. Sanjay and Prasad [9] showed that in an intercooled combustion-turbine based CCPP, the maximum cycle efficiency occurred at a lower value of intercooling pressure ratio while the maximum plant work output happened at a higher value of that. Bassily [10] modified different gas turbine cooling techniques for modern commercial CCPPs.…”

“…To obtain the effective utilization of heat energy, it is necessary to amalgamate different cycles (Maheshwari and Singh, 2020) while incorporating intercooling and reheating as the most suitable technique to increase the productivity of cycles. An IcGT, triple pressure reheat steam cycle is compared with a simple cycle GT with steam cycle (Sanjay and Prasad, 2013). The solar-based IcGT and Kalina cycle are investigated in Peng et al (2012), the results showed that at 10,000°C inlet temperature of a turbine, the GT efficiency is 27.5% of 800 W/m 2 solar direct normal irradiances.…”

Purpose This paper aims to analyze energy and exergy analysis of solar-based intercooled and reheated gas turbine (GT) trigeneration cycle using parabolic trough solar collectors (PTC) with the use of MATLAB 2018. Design/methodology/approach In the first section of this paper, the solar-based GT is validated with the reference paper. According to the reference paper, the solar field is comprising 30 modules in series and 35 modules in parallel series, where a total of 1,050 modules of PTC are taken into consideration. In the second part of this paper, the hybridization of the solar, GT trigeneration cycle is analyzed and optimized. In the last section of this paper, the hybridization of solar, intercooled and reheated GT trigeneration systems is examined and compared. Findings The results examined the first section, the power produced by the cycle will be 37.34 MW at 0.5270 kg/s mass flow rate of the natural gas consumption and the efficiencies of energy and exergy will be 38.34% and 39.76%, respectively. The results examined in the second section, the power produced by the cycle will be 38.4 MW at 0.5270 kg/s mass flow rate of the natural gas consumption and accordingly the efficiency of energy and exergy is found to be 40.011% and 41.763%. Where in the last section, the power produced by the cycle will be 41.43 MW at 0.5270 kg/s mass flow rate of the natural gas consumption and the energy and exergy efficiencies will be 39.76% and 40.924%, respectively. Originality/value The author confirms that this study is original and has neither been published elsewhere nor it is currently under consideration for publication elsewhere.

En la actualidad, hay diversas formas para generar energía eléctrica, una de ellas consiste en aprovechar la cantidad de energía liberada al quemar un combustible y efectuar una serie de procesos de conversión de energía mediante un ciclo termodinámico. Para hacer estos procesos más eficientes, existen herramientas que permiten analizar en qué equipos de la planta se está desaprovechando energía, una de estas técnicas es el análisis exergético, que consiste en la aplicación simultanea de la primera y segunda ley de la termodinámica. En el presente trabajo se realiza el análisis exergético a una planta de generación de electricidad y calor a partir de la producción de vapor operando bajo un ciclo combinado. Inicialmente se definen conceptos importantes para realizar el análisis. Después de aplicar la primera y segunda ley de la termodinámica los resultados indican que la eficiencia exergética de la planta de ciclo combinado es 53% y se encuentra que la cámara de combustión es el componente del sistema que más exergía destruye y que las bombas son los dispositivos donde hay menor pérdida de energía útil.
