Dish layouts analysis method for concentrative solar power plant

Designs leading to maximize the use of sun radiation of a given reflective area without increasing the expense on investment are important to solar power plants construction. We here provide a method that allows one to compute shade area at any given time as well as the total shading effect of a day. By establishing a local coordinate system with the origin at the apex of a parabolic dish and z...

Thermodynamic analysis of an idealised solar tower thermal power plant

In the real solar tower thermal power system, it is widely acknowledged that the thermodynamic irreversibility, such as convective and radiative loss on tower receiver, and thermal resistance in heat exchangers, is unavoidable. With above factors in mind, this paper presents an ideal model of the solar tower thermal power system to analyze the influence of various parameters on thermal and exer...

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...

Modelling of a 400m steam based Paraboloidal Dish concentrator for solar thermal power production

The Australian National University has a 400m Paraboloidal dish solar concentrator system, informally named “the Big Dish” that produces superheated steam via a receiver mounted monotube boiler. The system, (shown in Figure 1) which is the worlds largest was constructed in 1994. This paper describes the results of the latest experimental tests plus associated system performance modelling. The s...
