Description: TITLE:
A SOLAR THERMAL CONCENTRATOR AND METHOD OF MAKING THE SAME

FIELD OF INVENTION:
The present invention is related to a concentrator for solar thermal energy. More particularly, the present invention related to design of solar concentration dish and method of making the same.

BACKGROUND OF INVENTION:
The demand of heat energy increases day-by-day. There is different usage of the heat energy in various sectors such as industries like milk processing, sugar industries, agro industries, chemical processing plants, pharma industries, textiles industries etc requires thermic fluid heating in various processes in the industry. To fulfil the demand of energy, it imparts burden to import fossil fuel. The fossil fuels include coal, oil, biomass, natural gas etc. These sources are limited, non-renewable as well as responsible for the greenhouse effect. India has a renewable source of energy that is solar energy. This is sustainable solution for energy.
The heat energy is collected from the sun by concentrating solar irradiance (solar
power). There are various ways of generating solar thermal energy i.e., solar power, parabolic trough, and parabolic dish. The available parabolic dish applicator consists of primarily a concentrator (reflector), a receiver (absorber), heat transport media/storage and energy conversion or transmission and it has dual-axis tracking system. Mostly parabolic dish systems are equipped with an external combustion engine at the focal area which converts solar to electric energy. This external combustion engines are too expensive and require special care to maintain. The presently available parabolic dish is designed in such a way that it sustains the wind load. To make the parabolic dish which sustain the heavy load of wind requires heavy material which increases weight of the dish and impact on construction cost that is increased.

Therefore, there is need of the parabolic dish which use to convert solar energy into the thermal energy and also solve at least one of the aforementioned problems.

The appearances of the phrase “in an embodiment” in various places in the specification are not necessarily all referring to the same embodiment.
The present invention describes a solar thermal concentrator and method of making the solar thermal concentrator. The solar thermal concentrator is worked as solar boiler.
Accordingly, the present invention provides a solar thermal concentrator (100). The solar thermal concentrator (100) is solar parabolic dish type concentrator.
According to present invention, Fig. 1 shows the solar thermal concentrator (100) comprising a receiver (101), a set of mirrors (102), a main frame (103), a fluid pipe (104), a roller (105), a rotating path (106), and a steam pipe (107).
In an embodiment of the present invention, the receiver (101) contains more than two layers. The receiver (101) is consisting of insulation sheet (201), glass wall (202), copper coil (203) and cavity (204) shown in fig. 2. The outer layer of receiver (101) is insulation sheet (201) made up from the metal includes aluminium sheet, steel sheet.
