Se encuentra apoyado y soportado sobre dos chumaceras en cada extremo, separadas 6. The cylinder-parabolic solar concentrator is a mechanism of one degree of freedom, which was built with tubular profiles of different caliber. This is supported on two bearings at each end separated 6. The parabolic profile built by placing the stainless steel sheet type with mirror end on profiles of flawing PTR with form of parable previously established. The focal line of the parable coincides with the axis of rotation of the solar concentrator. It is important to mention that there are three solar modules with a superface of 24 m 2 each one, thus having a superface of 72m 2.

Volkis Classification de thermal solar concentrators Solar collectors can be classified depending on their geometric configuration or on the concenttradores obtained by the working fluid after gaining heat.
Figure 5 shows the waste water evaporation system installed in India, which permits parwbolicos of concentradorss waste liquids from pharmaceutical industries, hospitals, and processing plants   4. Using solar systems to desalinate water requires large areas of land and it is not as efficient when compared to conventional systems non-solarbut its low cost and ease of implementation make it one of the most promising technologies among the applications using direct radiation from the sun  .
It is worth mentioning that other countries like Algeria 25 MWThailand 9. Additionally, the system has an oil boiler that guarantees its operation under all conditions . Concentraadores system permits increasing efficiency and reducing installation costs compared to cylindrical collectors Figure 4.
This comprises a group of heliostats flat reflectors aligned in circular manner. Feasibility study of one axis three positions tracking solar PV with low concentration ratio reflector. These industries use fields of collectors to heat water and produce vapor used in paper drying Figure 7. Los mismos permiten paliar la ausencia de sol hasta 15h. Design and construction of non-imaging planar concentrator for paranolicos photovoltaic system.
Usually, it is used in electric power generation facilities with large power capacity. In addition to the aforementioned, energy consumption is reduced to a minimum. Con el objeto de alcanzar una cobertura solar total, se investigan y se ensayan en los laboratorios, soluciones de almacenamiento de calor sobre prototipos a diferentes escalas, durante varios meses.
Linear dielectric non-imaging concentrating covers for PV integrated building facades. It is found on the device focus when working with spherical or cylindrical geometries. The sun, as main source of light and heat for the earth, is considered an inexhaustible resource of energy, of easy access, free, clean, and renewable; from which it is possible to obtain direct benefits through systems capable of transforming the direct solar radiation into other types of useful energy to then be used in industrial processes or in small applications for the home.
Thermo solar technologies are still a favorable option to combat the use of nonrenewable energy sources, like coal and petroleum derivates, contributing to CO 2 reduction in the environment and associated costs.
The thermal condenser is a storage device where the fluid at high temperatures is deposited and which significantly reduces energy losses, given that it minimizes heat exchange with the environment because of the thermal isolation with which it was designed    One of the advantages offered by this system against the rest is that it permits storing part of the energy obtained during the day for later use, during night hours or during days with low levels of solar radiation Figure 3.
Se necesita un espesor muy reducido para absorber la luz visible: Figure 14 presents the places and types of technology of the concentradroes plants under construction, highlighting the plants located in California, like: How to cite this article. Structurally, solar concentrators comprise three so,ares elements for their functioning, which are mentioned ahead:. Concentrator or optical device: The fluid can be stored in a thermal condenser for later concenfradores or it can be brought directly to a heat exchanger where solzres is produced to propel a turbine and a generator as done with parabolic cylindrical collectors.
A la hora de elegir los reactivos, existen importantes restricciones: This air is circulated through open spaces, with which a constant temperature is maintained, reducing electric energy consumption. Under these conditions, it is expected that the regions with the highest strengthening of the technology will be Europe, the United States, the Middle East, and China. Y eso de manera proporcional: The rows of collectors of Shams 1 generate energy that avoids the emissions oftons of CO 2 per year, which is equivalent to removing 15, automobiles from circulation .
At m above sea level, and when solar radiation peaks are reached on certain days, the system can provide approximately 38, meals. Assessment of the potential improvement due to multiple apertures in central receiver systems with secondary concentrators.
Global energy consumption grows rapidly due to factors like population increase and technological so,ares, increasing energy production requirements in its different forms, with electric energy and parabolics energy having the highest demand. Figure 15 shows the Shams 1 parabolic cylindrical plant, which has MW capacity and permits providing energy parabolicis some 20, homes. For this, boilers are used to produce vapor yielded through heat exchangers to reservoirs to heat water or intermediate products; in other cases, vapor is used directly.
Luego, el procedimiento es el mismo que para otros tipos de centrales: In other versions, energy is used to generate water vapor that is used to propel a vapor turbine and a generator. Development of thermo solar energy depends on direct solar radiation, sun shine, availability of surface area, and auxiliary services like water, gas, and electric networks. TOP Related.
