A Design Program of A Parabolic Dish- Solar Collector for Food Industry

Abstract

Due to the expected shortage in conventional sources of energy, solar energy is considered the most important source of renewable energy which its usage is not subjected to political economical agenda, but required a huge equipment for collecting solar radiation proportional to the low intensity of energy per unit area. In this research , a Matlab program was developed to be use for designing and calculation of a parabolic solar dish collector dimensions. This program calculated the dimension of such solar collector which is considered to have a coefficient of performance of 67% to produce the required steam at the required pressure and temperature by knowing the location of the application. By testing the program, the program yields good results that validate the program and from it a value of the diameter in the range of (253-758 meter) is found, when we need to generate a quantity of steam in the range of (10 - 90 kg/s), results shows that the program could be used successfully in designing the dimension of the parabolic solar dish collector.
