9.1. Introduction Dish concentrating solar power (CSP) systems use parabo.loidal mirrors that track the sun and focus solar energy into a receiver where it is absorbed and transferred to a heat engine/generator or else into a heat transfer fluid that is transported to a ground-based plant.
The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use. The two major parts of the system are the solar concentrator and the power conversion unit.
Dish/engine sys tems convert the thermal energy in solar y in much the way same that conventional power plants convert o electricity. As indicated in Figure 1, dish/engine incoming systems norm al insolation to a receiver, in order to achieve s the requires that the dish track the sun in two axes. The d transferred to an engine. . Figure 1.
A dish system consists of (a) a paraboloidal shaped concentrator, (b) tracking system, (c) solar heat exchanger (receiver), (d) an (optional) engine with a generator, and (e) a system control unit ( Fig. 9.1 ). The concentrator tracks the sun biaxially in such a way that the optical axis of the concentrator always points to the sun.
Dish can attain extremely high temperatures, and holds promise for use in solar reactors for making solar fuels which require very high temperatures. Stirling and Brayton cycle engines are currently favored for power conversion, although dish has been seldom deployed commercially for power generation. Dish deployment database.
