Concentrador solar

Drying of agricultural and industrial products requires constant hot air to eliminate humidity. Las reacciones previstas son las deshidrataciones, en verano, y las hidrataciones, en invierno. In most cases, the thermal energy obtained is used to generate vapor with water or alcohol and propel vapor turbines with which energy is produced; there is also the option of storing saline solutions or parabolicps oils at high temperatures to later use this energy when there is no direct radiation or at night.

Water desalination is achieved through successive stages. Classification de thermal solar concentrators Solar collectors can be classified depending on their geometric configuration or on the temperature obtained by the working fluid after gaining heat. Concentrador de la radiacion solar, con espejos parabolicos multiplesindependientes.

Figure 5 shows the waste water evaporation system installed in India, which permits incineration of hazardous waste liquids from pharmaceutical industries, hospitals, and processing concenttadores [11] [12]. Additionally, the system has an oil boiler that guarantees its operation under all conditions [16].

En este caso, el agua circula por una red de tubos negros paralelos y se calienta lentamente. 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 Concentradorws 2 emissions for the environment, which could diminish emission to 5-billion tons annually within an advanced scenario by [22].

It is used for electric power generation and for devices requiring high temperatures like furnaces to incinerate hazardous wastes. A tower is located in the center of the circumference, which captures the radiation reflected by the heliostats. For this, boilers are used to produce vapor yielded through heat exchangers to reservoirs to heat water or intermediate products; in other cases, vapor concenyradores used directly. 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].


El segundo precursor es el agua H2O. Services on Demand Article. In these industries for example manufacture of cosmetic products numerous processes exist requiring heating.


Este diaporama presenta algunas de sus aplicaciones. It is worth mentioning that other countries like Algeria 25 MWThailand 9. The type of working fluid used in this type of collector is usually demineralized water or ethylene glycol. These devices permit direct use of the energy obtained or its transformation into another type of useful energy [1] [2] [3]. El bajo potencial solar de Francia continental se usa principalmente para justificar este cierre: Se necesita un espesor muy reducido para absorber la luz visible: Advantages and disadvantages of thermo solar technologies Table 2 presents the advantages solates disadvantages of thermo solar technologies, bearing in mind relevant aspects like their operating temperature, efficiency, materials for concenteadores construction, storage capacity, among others.

Table 2 presents the advantages and disadvantages of thermo solar technologies, conccentradores in mind relevant aspects like their operating temperature, efficiency, materials for their construction, storage capacity, among others. Solar energy collecting system using a primary reflector based on a pyramid structure.

The system is basically comprised of a collector, a heat exchanger receptorand a solar tracking system that aims the collector directly at the sun during the day.

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.

Solar receptor systems or Central tower This comprises a group of heliostats flat reflectors aligned in circular manner. Usually, it is used in electric power generation facilities with pagabolicos power capacity.

Unlike cylindrical collectors, this system uses a single receptor that captures the radiation reflected by several pparabolicos reflectors.

Su capacidad es de 31 MWc. Este silicio de estructura desordenada y no cristalina presenta una gran ventaja.

To meet these requirements, it is indispensable to use fossil fuels like coal, oil, and natural gas, but these generate negative effects because of the emission of residues and contaminating gases onto the environment, as well because of their high costs. Esta granja solar puede proveer electricidad a 12 hogares. Los mismos permiten paliar la ausencia de sol hasta 15h.


The hot fluid is taken to a heat exchanger where thermal energy is used to generate water vapor, which propels a vapor turbine connected to an electric generator. De esta manera, los electrones son repelidos hacia la capa N y los huecos hacia la capa P.

Esta central gigante se puso en funcionamiento progresivamente a partir de mayo de Although thermo solar systems have a vast number of applications in the industrial sector, electric energy production has most-influenced sector by these types of technologies. Via dish-type solar collectors, heat is produced that is circulated through the crops, fruits, or products, eliminating water on them. Within this sensor tube circulates the fluid that absorbs the thermal energy obtained heating until reaching the desired temperature.

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].

En consecuencia, la cantidad de materiales es inferior a la necesaria para un almacenamiento por calor sensible.

Sus 2 espejos pivotantes representan una superficie de m2. Feasibility study of one axis three positions tracking solar PV with low concentration ratio reflector. Design and construction of non-imaging planar concentrator for concentrator photovoltaic system.

The water vapor generated is taken to a cooling system condenser to condense it, thus, obtaining distilled water that is then stored in an adequate container.

Figure 5 shows the waste water evaporation system installed in India, which permits incineration of hazardous waste liquids from pharmaceutical industries, hospitals, and processing plants [11] [12] 4. 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. Table 1 indicates how these are classified according to the temperature reached: Country of ref document: Se prueban actualmente algunos prototipos para so,ares de a soles.
