Exergy Analysis of a Pilot Parabolic Solar Dish-Stirling System

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%, res...

AMMONIA RECEIVER DESIGN FOR A 500m DISH

Previous ammonia receiver development has been limited to computational evaluation of receiver geometries. This paper compares six months of experimental data to these simulations. Although the simulation was calibrated with experimental data from the unmasked 20 m 2 dish, the simulated efficiencies for the masked 9 m 2 dish were 2-3 times the magnitude of the experimental simulations. However,...

Ammonia Receiver Design for Dish Concentrators

This paper describes a general method for evaluating receiver designs for ammonia-based energy storage with dish concentrators. The method involves ray-tracing to determine the concentrated solar flux profile on the reactor surface, followed by a simulation which calculates reaction extents and heat losses. In this paper, five receiver designs were investigated with varying cone angles and plac...
