This paper presents a conceptual configuration of a solar dish based combined cycle power plant with a topping gas turbine block and a bottoming steam turbine cycle coupled through a heat recovery steam generator (HRSG). Carbon dioxide has been considered as the working fluid for the topping cycle and it has been considered in gaseous state all through the cycle. Two-stage compression has been proposed for the carbon dioxide cycle. The conventional GT combustion chamber is replaced by a high-temperature directly irradiated annular pressurized receiver (DIAPR) consisting of cavity and tubular sections. Detail thermodynamic study has been performed for varying second stage pressure ratioand for varying gas turbine inlet temperature for the combined cycle keeping first stage pressure ratio fixed at 3.The gas turbine inlet temperature has been varied from 625 O C to 900 O C. The study reveals that work output of the combined cycle is maximum when the pressure ratio of the second stage compression is 2. Parametric exergetic analysis has also been performed for the components like dish, solar receiver and stack. The exergy analysis shows that the solar receiver contributes to maximum exergy destruction.

“…Similar calculations are used to determine component sizes for this study. The solar costs were compared to similar, albeit different, solar heated gasification facilities and the systems were comparable in most aspects [17,18]. The conventional system materials and costs were acquired from government agency reports and then adjusted to 2012 dollar values [1,6].…”

“…A techno-economic assessment of the 100 MW solar thermal dish-Stirling technology was performed to estimate the thermal energy and the levelized energy cost [13]. A rim angle of 45 • was suggested for the design of the system solar collector by investigators [9,[14][15][16], taking into consideration the highest concentration ratio and thermal performance.…”

Energy and exergy analyses were carried out for a pilot parabolic solar dish-Stirling System. The system was set up at a site at Kerman City, located in a sunny desert area of Iran. Variations in energy and exergy efficiency were considered during the daytime hours of the average day of each month in a year. A maximum collector energy efficiency and total energy efficiency of 54% and 12.2%, respectively, were predicted in July, while during the period between November and February the efficiency values were extremely low. The maximum collector exergy efficiency was 41.5% in July, while the maximum total exergy efficiency reached 13.2%. The values of energy losses as a percentage of the total losses of the main parts of the system were also reported. Results showed that the major energy and exergy losses occurred in the receiver. The second biggest portion of energy losses occurred in the Stirling engine, while the portion of exergy loss in the concentrator was higher compared to the Stirling engine. Finally, the performance of the Kerman pilot was compared to that of the EuroDish project.
