“…One similar example of a solar-assisted gas turbine is studied by Bellos, Tzivanidis, and Antonopoulos (2017b). The pressure ratio is limited by inlet air temperature at the solar field (outlet compressor air temperature) unless intercooled compression is implemented (Dabwan et al, 2022). The use of a linear concentrating collector as the unique heat source in the power cycle has been studied to less extent, aiming at lower maximum temperature and modest efficiency, considering the Brayton cycle (Ferraro & Marinelli, 2012), or a discrete steps Ericsson cycle (Cinocca et al, 2018).…”

Parabolic trough collectors and linear Fresnel collectors are mature technologies for power production, and they are being recently applied to provide solar heat for industrial needs. Conventionally, they use a liquid as heat transfer fluid, either thermal oil or water, to carry heat from the receivers up to the point of conversion or delivery. Although liquids offer excellent thermal properties, they show technical limitations, besides environmental concerns, which have encouraged the research on alternative solutions. This work reviews the main research works on the use of gases as heat transfer fluid in linear concentrating collectors, including solar power and heat production, highlighting the potential applications and technical challenges. The review indicates: first, gases offer potential to replace liquids, and second, there is a need for more research and development to define the best technical compromises to reach practical application in every sector.

“…Results revealed that, by using the solar field and the ORC plant, the system exhibits enhanced efficiency and power output. Dabwan et al [24] assessed and developed a gas turbine system with intercooling applicable to power utilities that incorporated solar preheating to improve efficiency and reduce greenhouse gas and other emissions. Evaluating system performance with thermodynamic simulation and analysis demonstrated that the energy and exergy efficiencies of the system exceed those for a conventional gas turbine system.…”

The current study investigates a cogeneration system based on a gas turbine, integrated with a Rankine cycle and an absorption refrigeration cycle, considering energy and exergy perspectives. The fuel used in the gas turbine’s combustion chamber is obtained through biomass gasification, specifically using wood as the biomass fuel. To enhance the system’s performance, solar energy is utilized to preheat the working fluid in the Rankine cycle, reducing the energy required in the heat recovery steam generator. Additionally, an absorption refrigeration cycle is incorporated to recover waste heat from exhaust gases and improve the plant’s exergy efficiency. A two-objective optimization is conducted to determine the optimal operating conditions of the proposed system, considering exergy efficiency and carbon dioxide emission index as criteria. The case study reveals that the gasifier and combustion chamber contribute the most to system irreversibility, accounting for 46.7% and 22.9% of the total exergy destruction rate, respectively. A parametric study is performed to assess the impact of compression ratio, turbine bleed steam pressure, gas turbine inlet temperature, and solar share (the ratio of energy received by solar collectors to biomass fuel input energy) on system performance. The findings demonstrate that maximum energy and exergy efficiencies of the power generation system are achieved at a pressure ratio of 10. Furthermore, a 1% reduction in the gas turbine’s compression pressure ratio can be compensated by a 9.3% increase in the solar share within the steam Rankine cycle.
