EL OBJETIVO DEL PRESENTE PROYECTO ES PROPONER NUEVOS DESARROLLOS PARA UN MEJOR APROVECHAMIENTO DE LA ENERGIA SOLAR EN CENTRALES TERMOSOLARES DE CONCENTRACION, QUE CONSIGAN MEJORAR SIGNIFICATIVAMENTE EL RENDIMIENTO DE ESTE TIPO DE CENTRALES Y LAS HAGAN MAS COMPETITIVAS FRENTE A LAS CENTRALES TERMICAS CONVENCIONALES. CONCRETAMENTE, LA MEJORA PROPUESTA CONSISTE EN UTILIZAR PARTICULAS EN LUGAR DE FLUIDOS, COMO ACEITES TERMICOS O SALES FUNDIDAS, COMO MEDIO CALOPORTADOR EN EL RECEPTOR SOLAR Y COMO SISTEMA DE ALMACENAMIENTO ENERGETICO. LA RADIACION SOLAR SE CONCENTRARA DIRECTAMENTE SOBRE LAS PARTICULAS, ELIMINANDO EL USO DE TUBOS Y LOS PROBLEMAS DE ESTRES TERMICO QUE DEBEN SOPORTAR A ALTAS TEMPERATURAS. DE ESTA MANERA SE PUEDEN ALCANZAR TEMPERATURAS CERCANAS A LOS 1000 ºC, MUY POR ENCIMA DEL LIMITE DE 560 ºC IMPUESTO EN LAS CENTRALES SOLARES DE TORRE DE CONCENTRACION CON SALES FUNDIDAS COMO FLUIDO DE TRABAJO ACTUALES._x000D_ _x000D_ COMO TECNOLOGIA FLUIDO-PARTICULA SE PRETENDEN ESTUDIAR EXPERIMENTALMENTE DIFERENTES TECNOLOGIAS: LECHOS FLUIDIZADOS BURBUJEANTES (CON FLUIDIZACION HOMOGENEA Y NO-HOMOGENEA) Y LECHOS FLUIDIZADOS TIPO ¿SPOUTED¿ Y ¿SPOUT-FLUID¿. LOS LECHOS FLUIDIZADOS SE CARACTERIZAN POR UNOS ALTOS NIVELES DE MEZCLADO Y DE DISPERSION EN EL INTERIOR DEL LECHO, LO QUE LOS HACE IDONEOS PARA ESTA APLICACION, DONDE ES NECESARIO DISTRIBUIR RAPIDAMENTE LA ENERGIA SOLAR CONCENTRADA SOBRE LA SUPERFICIE DEL LECHO A LO LARGO DE TODO EL VOLUMEN DE PARTICULAS. CON LA FLUIDIZACION NO-HOMOGENEA, DONDE SE INTRODUCE UN FLUJO DE AIRE DIFERENTE POR LA ZONA CENTRAL AL DE LA PERIFERIA, SE PERSIGUE MEJORAR LOS COEFICIENTES DE DISPERSION DE SOLIDOS, QUE ES EL PROCESO DOMINANTE EN LA DISTRIBUCION DE LA ENERGIA EN UN LECHO FLUIDIZADO._x000D_ _x000D_ SE HARA UNA REVISION COMPLETA DE LAS DIFERENTES PARTICULAS DISPONIBLES Y SE CARACTERIZARAN SUS PRINCIPALES PROPIEDADES: DENSIDAD, TAMAÑOS, ABSORTIVIDAD, ETC. SE ESTUDIARAN PARTICULAS CON TAMAÑOS COMPRENDIDOS ENTRE 0.1 Y 0.7 MM APROXIMADAMENTE, QUE SERAN UTILIZADAS EN UN LECHO FLUIDIZADO BURBUJEANTE, Y TAMAÑOS DE HASTA UNOS POCOS MILIMETROS, QUE SON MAS APROPIADOS DE UTILIZAR EL LECHOS TIPO ¿SPOUTED¿ Y ¿SPOUT-FLUID. SE CONSTRUIRA UNA INSTALACION EXPERIMENTAL CON RADIACION CONCENTRADA, A ESCALA DE LABORATORIO, QUE PERMITA ENSAYAR EXPERIMENTALMENTE LAS PARTICULAS SELECCIONADAS EN LAS DIFERENTES TECNOLOGIAS FLUIDO-PARTICULA PROPUESTAS Y CARACTERIZAR LOS TIEMPOS DE CALENTAMIENTO Y LOS COEFICIENTES DE DISPERSION DE SOLIDOS EN CADA CASO._x000D_ _x000D_ DE ENTRE TODAS LAS COMBINACIONES DE PARTICULAS Y TECNOLOGIAS FLUIDO-PARTICULA ENSAYADAS, SE ESCOGERA AL MENOS UNA COMBINACION, QUE SE CONSIDERE LA MAS IDONEA PARA LA APLICACION PROPUESTA. PARA ESTE CASO, SE REALIZARA UNA SIMULACION NUMERICA A TAMAÑO INDUSTRIAL DEL SISTEMA, CON EL OBJETIVO DE DIMENSIONAR Y OPTIMIZAR UN SISTEMA A ESCALA REAL. PARA ESTE FIN SE UTILIZARA UN PROGRAMA DE SIMULACION NUMERICA ESPECIFICO DE LECHOS FLUIDIZADOS Y FLUJOS PARTICULARES. (Spanish)

THE OBJECTIVE OF THIS PROJECT IS TO PROPOSE NEW DEVELOPMENTS FOR A BETTER USE OF SOLAR ENERGY IN CONCENTRATED THERMAL POWER PLANTS, WHICH WILL SIGNIFICANTLY IMPROVE THE PERFORMANCE OF THIS TYPE OF POWER PLANTS AND MAKE THEM MORE COMPETITIVE COMPARED TO CONVENTIONAL THERMAL POWER PLANTS. SPECIFICALLY, THE PROPOSED IMPROVEMENT CONSISTS OF USING PARTICLES INSTEAD OF FLUIDS, SUCH AS THERMAL OILS OR MOLTEN SALTS, AS A HEATING MEDIUM IN THE SOLAR RECEIVER AND AS AN ENERGETIC STORAGE SYSTEM. THE SOLAR RADIATION WILL CONCENTRATE DIRECTLY ON THE PARTICLES, ELIMINATING THE USE OF TUBES AND THE PROBLEMS OF THERMAL STRESS THAT THEY MUST WITHSTAND AT HIGH TEMPERATURES. From this way TEMPERATURES can be reached at 1 000 °C, as much as 560 °C LIMITE COUNCIL IN SOLAR CENTRALS OF CONCENTRATION TORRE WITH FULL ACTUAL WORKING SALES._x000D_ _x000D_ AS FLUITED-Partcula TECHNOLOGY TECHNOLOGY TECHNOLOGY TECHNOLOGY TECHNOLOGY PRODUCTS: FLUIDISED BED BUBBLES (WITH HOMOGENEOUS AND NON-HOMOGENATED FLUIDISATION) AND FLUIDISED BEDS TYPE SPOUTED AND SPOUT-FLUID. FLUIDISED BEDS ARE CHARACTERISED BY HIGH LEVELS OF MIXING AND DISPERSION INSIDE THE BED, WHICH MAKES THEM IDEAL FOR THIS APPLICATION, WHERE IT IS NECESSARY TO QUICKLY DISTRIBUTE CONCENTRATED SOLAR ENERGY OVER THE SURFACE OF THE BED ALONG THE ENTIRE VOLUME OF PARTICLES. With NON-HOMOGENEA fluidisation, WHERE A FLUDE OF AIR DIFFERENT IN THE CENTRAL ZONE OF THE PERIFERIA, it is intended to improve the COEFICIENTS OF DISPERSION OF SOLIDOS, which is the dominant process in the distribution of ENERGY in a FLUIDICE RECHOUSE._x000D_ _x000D_ _x000D_ there will be a complete review of the different parts available and will be characterised by their primary Ownerships: DENSITY, SIZES, ABSORPTION, ETC. WILL BE STUDIED PARTICLES WITH SIZES BETWEEN 0.1 AND 0.7 MM APPROXIMATELY, WHICH WILL BE USED IN A FLUIDISED BUBBLING BED, AND SIZES OF UP TO A FEW MILLIMETERS, WHICH ARE MORE APPROPRIATE TO USE THE BED TYPE SPOUTED AND SPOUT-FLUID. An EXPERIMENTAL INSTALLATION WITH CONCERNING RADIATION will be constructed, at LABORATORY SCALE, which will permit experimental testing of the PARTICULES Selected IN THE DIFFERENT TECHNOLOGIAS FLUITED-particulates PROPOSES AND characterising QALENTATING TIME AND COEFICIENTS OF SOLID DISPERSION IN EVERY HOUSE._x000D_ _x000D_ BETWEEN ALL COMBINEMENTS OF PARTICULES AND TECHNOLOGIES FLUITED-Partcula tested, A COMBINANCATION is considered to be the most suitable for the proposed application. IN THIS CASE, A NUMERICAL SIMULATION TO INDUSTRIAL SIZE OF THE SYSTEM WILL BE PERFORMED, WITH THE AIM OF DIMENSIONING AND OPTIMISING A SYSTEM ON A REAL SCALE. FOR THIS PURPOSE, A SPECIFIC NUMERICAL SIMULATION PROGRAM OF FLUIDISED BEDS AND PARTICULAR FLOWS WILL BE USED. (English)
