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 parzbolicos obtain direct benefits through systems capable of transforming the direct solar radiation into other concenttadores of useful energy to then be used in industrial processes or in small applications for the home. This system permits increasing efficiency and reducing installation costs compared to cylindrical collectors Figure 4.
El bajo potencial solar de Francia continental se usa principalmente para justificar este cierre: Linear dielectric non-imaging concentrating covers for PV integrated building facades.
La primera utiliza parxbolicos capacidad de los materiales para aumentar su temperatura sin cambiar de estado. It is used for electric power generation and for devices requiring high temperatures like furnaces to incinerate hazardous wastes. Drying of agricultural and industrial products requires constant hot air to eliminate humidity.
The following present the main applications of these thermo solar elements.
Su alto precio se ve compensado por ventajas irrefutables: 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 synthetic oils at high temperatures to later use this energy when there is no direct radiation or at night.
These are devices that permit focusing radiation from the sun on a reduced area focusto concentrate thermal energy and light to easily use it with devices like Stirling motors, heating systems, solar kitchens, vapor turbines, or photovoltaic cells among other devices that operate with thermal energy or with the visible radiation from the sun.
Additionally, the system has an oil boiler that guarantees its operation under all conditions  At m above sea level, and when solar radiation peaks are reached on certain days, the system can provide approximately 38, meals. 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.
A tower is located in the center of the circumference, which captures the radiation reflected by the heliostats. Solar receptor systems or Central tower This comprises solarws group of heliostats flat reflectors aligned in circular manner.
CONCENTRADOR SOLAR TIPO PARABOLICO by CARLOS HUGO MARTINEZ on Prezi
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. Thermo solar technologies are still a favorable option to combat the use of nonrenewable energy condentradores, like coal and petroleum derivates, contributing to CO 2 reduction in the environment and associated costs.
Sus 2 espejos pivotantes representan una superficie de m2. Esta central gigante se puso en funcionamiento progresivamente a partir de mayo de Conclusions 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.
Las reacciones previstas son las deshidrataciones, en verano, y las hidrataciones, en invierno. How to cite this article.
Classification de concentrradores solar concentrators Solar collectors can be classified depending on their geometric configuration or on the temperature obtained by the working fluid after gaining heat. Many places exist like the Middle East and Africa that do not have enough water suitable for human consumption, even though they coastal zones with access to the sea.
Structurally, solar concentrators comprise three necessary elements confentradores their functioning, which are mentioned ahead: En el laboratorio, los investigadores logran hacer crecer silicio cristalino con procedimientos plasma de baja temperatura. Central solar de torre.

De esta manera, los electrones son repelidos hacia la capa N y los huecos hacia la capa P. This system offers advantages with parabolics to others, given that the product remains free of dirt, dust, and its flavor and texture are maintained.
The concentrator is a device constructed concentradpres 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.
According to their geometric configuration they can be flat solar collectors and concentrating solar collectors. Figure 11 illustrates the map of direct solar radiation in the world; note that Argeria, Australia, China, Egypt, Greece, India, Israel, Italy, Mexico, Morocco, Spain, and the United States are suitable places for the development of thermo-solar technologies.

Figure 14 presents the places and types of technology of concentradres thermo-solar plants under construction, highlighting the plants located in California, like: Assessment of the potential improvement due to multiple apertures in central receiver systems with secondary concentrators.
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. These devices permit direct use of the energy obtained or its transformation into another type of useful energy    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.
Usually, very low and low temperature collectors are used for heating devices like water heaters and paabolicos kitchens. Structurally, solar concentrators comprise three necessary elements for their functioning, which are mentioned ahead:. Kind code of ref document: A la hora de elegir los reactivos, existen importantes restricciones: Solar collectors can be classified depending on their geometric configuration or on the temperature obtained by the working fluid after gaining heat.
