RT Journal Article T1 Comparison of Different Technologies for Integrated Solar Combined Cycles: Analysis of Concentrating Technology and Solar Integration A1 Rovira de Antonio, Antonio José A1 Sánchez, Consuelo A1 Valdés, Manuel A1 Abbas, Rubén A1 Barbero Fresno, Rubén A1 Montes, María José A1 Muñoz Domínguez, Marta A1 Muñoz Antón, Javier A1 Ortega Ruiz, Guillermo A1 Varela, Fernando AB This paper compares the annual performance of Integrated Solar Combined Cycles(ISCCs) using different solar concentration technologies: parabolic trough collectors (PTC), linearFresnel reflectors (LFR) and central tower receiver (CT). Each solar technology (i.e. PTC, LFRand CT) is proposed to integrate solar energy into the combined cycle in two different ways.The first one is based on the use of solar energy to evaporate water of the steam cycle by meansof direct steam generation (DSG), increasing the steam production of the high pressure level ofthe steam generator. The other one is based on the use of solar energy to preheat the pressurizedair at the exit of the gas turbine compressor before it is introduced in the combustion chamber,reducing the fuel consumption. Results show that ISCC with DSG increases the yearly productionwhile solar air heating reduces it due to the incremental pressure drop. However, air heatingallows significantly higher solar-to-electricity efficiencies and lower heat rates. Regarding the solartechnologies, PTC provides the best thermal results.
