    • An integrated approach for the design of a custom-tailored hybrid solar MGT with an integrated solar receiver for the use in a small-scale solar dish unit is presented in order to overcome the inherent limitations of adapting a MGT in the desired power range to solar operation. The resulting MGT-dish equipped with the ‘optimal’ MGT shows a nominal conversion efficiency of 29.6%. Then, a thermoeconomic analysis of the entire system is performed to evaluate and compare the economic and environmental performance of the MGT-dish with a Dish-Stirling system. From an economical point of view the MGT-dish outperforms the dish-Stirling with LCoEs as low as 15.3€cts/kWhel compared to 22.4€cts/kWhel.

  • Integrated Design of a Hybrid Gas Turbine-Receiver Unit for a Solar Dish System
  • 2014
  • Ingår i: Proceedings of the International SolarPACES Conference 2014. Beijing, China. September 16-19, 2014. - : Elsevier BV.

    • An integrated design concept of a 25 KWel hybrid gas turbine-receiver unit is introduced in this paper. In this design, hot section; receiver, combustor and turbine, is integrated and located in the center of the unit in order to achieve a compact structure with low heat loss and cooling requirement. A ray tracing model is developed for analyzing the focal plane of the potential parabolic dish design and predicting the radiative flux boundary conditions of the receiver. An impinging cavity receiver, with a cylindrical absorber wall and a semi-spherical bottom, is chosen as the receiver for this hybrid unit. The cooling capacities of different impinging arrangements are calculated to determine the thermal boundary conditions on the cooling side. Finally, the optimal dimensions of the receiver are chosen as well as the impingement cooling design. A ‘single ring’ impinging array was found to be optimal for cooling down the wall temperature of the peak flux region to 1200 °C and provide a receiver exit temperature of 840 °C.
