Abstract
The main objective of this research was to design and assess a hybrid steam power station using a parabolic solar dish concentrator in place of a traditional boiler. A small station was built consisting of a solar dish (solar heater), working as a boiler,connected to a turbine which is, in turn, connected to an electrical generator. Outlet working fluid moves into a condenser and is then recycled back to the solar heater by a pump. The prototype comprised a solar dish with a diameter of 3m, aperture area reaching 7.1 m2, and focal length 1.41 m, covered with 2 mm glasses mirrored
/ silver tiles. The experimental data was gathered in situ over the summer and winter of 2020 – 2021 in order to assess performance over a range of weather conditions. The following parameters were assessed: 1- Energy and exergy loss in each component. 2- Energy and exergy efficiency for each device in the plant.
3- Power output in the turbine and generator. 4- The intensity of solar radiation, 24 hours a day, over the study period The system generates electricity from a renewable source, solar energy, and is more
efficient than solar cells which have been used in the past. The system is also economically viable because of the low initial cost of licenses and the absence of the need for fuel because of its reliance on renewable energy. It also has low maintenance costs which raises the potential to obtain substantial quantities of electrical energy at a reasonable price. The experimental results detail the generation of electricity by the solar dishpowered steam system which also makes use of other components found in large steam stations. New components were fitted to assist the work of the system and to facilitate its protection and operation in all seasons of the year under a variety of climatic conditions. The work of the system was tested on different days with promising results, the power produced ranging between 900 – 2000 w, this reflecting the difference between summer and winter.This study showed the potential of a composite system which can work with the
commercial systems that currently exist. The results also indicate that with the
increase in the number of solar dishes being used and exploitation of large areas available to fit dish fields, there exists the possibility to generate substantial quantities of electrical energy, powered by renewable energy, to reduce harmful emissions as well as reduce dependence on different types of fossil fuels.
