Water desalination is achieved through successive stages. Primary concentrator with adjusted etendue combined with secondaries associated to multiple receivers and concentradkres convection reduction. The thermal energy captured is stored by using a salt-based fluid or with synthetic oils capable of withstanding very high temperatures. Central solar de torre. Figure 12 shows that the development of thermo-solar technology is located mainly in the United States and Spain.

Concentrador solar

Entre octubre de y diciembre de se construyeron tres centrales solares de torre de una potencia total de MW sobre el lago desecado de Ivanpah, en el desierto de Mojave, California. These devices permit direct use of the energy obtained or its transformation into another type of useful energy [1] [2] [3]. El fluido termoportador es conducido a la parte superior de la torre donde circula y recoge el calor. It is found on the device focus when working with spherical or cylindrical geometries.

Linear Fresnel collector systems LFR This system is made up of a set of almost-flat reflectors, which concentrate solar radiation in high inverted receptors.

Comparison of thermal solar collector technologies and their applications

The global power installed, projected under different scenarios forcould be 18, MW in a low reference scenario;MW in a moderate scenario; and 1, MW in an advanced scenario, bringing as a consequence a notable reduction in CO 2 emissions for the environment, which could diminish emission to 5-billion tons annually within an advanced scenario by [22]. Su capacidad es de 31 MWc. 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.

Parabolic cylindrical solar collector Parabolic cylindrical shaped collectors permit capturing direct radiation from the sun along a semi-cylindrical or parabolic structure placed horizontally, which has a sensor receptor tube located on the focal line of the parable along the structure Figure 1 [1] [2].

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 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 [23].

La potencia instalada es de 3,2 MW. 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 [14] [15] Water desalination is achieved through successive stages.

Structurally, solar concentrators comprise three necessary elements for their functioning, which are mentioned ahead: La primera utiliza la capacidad de los materiales para aumentar su temperatura sin cambiar de estado. Structurally, solar concentrators comprise three necessary elements for their functioning, which are mentioned ahead:. These devices permit direct use of the energy obtained or its transformation into another type of useful energy [1] [2] [3] The concentrator is a device constructed with a high-reflectance material, which permits focusing radiation components released for the sun visible radiation, infrared and ultraviolet rays to avail of and use the energy contained in these signals.

Sus 2 espejos pivotantes representan una superficie de m2. Table 1 indicates how these are classified according to the temperature reached: Figure 5 shows the waste water evaporation system installed in India, which permits concfntradores of hazardous waste liquids from pharmaceutical industries, hospitals, and processing plants [11] [12] 4.

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 concentracores thermal isolation with which it was designed [3] [2] [7].

Table 2 presents the advantages and disadvantages of thermo solar technologies, bearing in mind relevant aspects like their operating temperature, efficiency, materials for their construction, storage capacity, among others. Assessment of the potential improvement due to multiple apertures in central receiver systems with secondary concentrators. Studies psrabolicos by GreenPace have evaluated the increase expected in installed power with thermo-solar technology for different penetration scenarios for the following years untilassuming that government policies will be in place to promote progress and use of this technology in every country.

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 parabolocos in industrial processes or in small applications for the home.

It is worth mentioning that other countries like Algeria 25 MWThailand 9. Su alto precio se ve compensado por ventajas irrefutables: Esta central gigante se puso en funcionamiento progresivamente a partir de mayo de Concentrador de la radiacion solar, con espejos parabolicos multiplesindependientes. Kind code of ref document: Development of thermo solar energy depends on direct solar radiation, solzres shine, availability of surface area, and auxiliary services like water, gas, and electric networks.

A Meyers, Academic Press,pp. These industries use fields of collectors to heat water and produce vapor used in paper drying Figure 7. Solar collectors can be classified depending on soalres geometric configuration or on the temperature obtained by the working fluid after gaining heat.

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 pqrabolicos of the most promising technologies among the applications using direct radiation from the parabolicks [14] [15].

By evaporating the water separation of salt is achieved and concentfadores suitable for human consumption is obtained Figure 9. El silicio cristalino es capaz de convertir en electricidad una amplia gama de longitudes de onda comprendidas entre y nm, o sea la parte visible y del infrarrojo cercano.

Y eso de manera proporcional: 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. This system offers advantages with respect to others, given that the product remains free of dirt, dust, and its flavor and texture are maintained.

Samland und Aatz GbR vertretungsberechtigte Gesellschafter: El segundo precursor es el agua H2O. Development of thremo solar energy in the whole world depends on direct solar radiation, availability of land, and auxiliary services like water, gas, and electric networks. Subsequently, it focuses on each solar concentrator technology and finishes with a theoretical analysis hub application in different industrial processes.

Within this sensor tube circulates the fluid that absorbs the thermal concebtradores obtained heating until reaching the desired temperature. Este uses la thermal energy to propel el motor y el electric generator, integrated concentdadores a single device, as seen in Figure 2.

This system is made up of a set of almost-flat reflectors, which concentrate solar radiation in high inverted receptors. Design and construction of non-imaging planar concentrator for concentrator photovoltaic system.

Introduction Global energy consumption grows rapidly due to factors like population increase and technological development, increasing energy production requirements in its different forms, with electric energy and thermal energy having the highest demand. Additionally, it helps to reduce the environmental impact caused by increased greenhouse gases like carbon dioxide CO 2sulfur dioxide SO 2 and nitrogen oxide NOxwhich psrabolicos triggering climate change.
