Title (EN) METHOD AND DEVICE FOR HEATING A TRANSLUCID GASEOUS MEDIUM BY MEANS OF CONCENTRATED SOLAR RADIATION
(FR) PROCEDE ET DISPOSITIF DE CHAUFFAGE D"UN MILIEU GAZEUX TRANSPARENT AU MOYEN D"UN RAYONNEMENT SOLAIRE CONCENTRE
Abstract: front page image
(EN)Quartz glass tubes (11) are arranged between a device (15, 16) used for bringing a translucid gaseous medium and and an evacuation device (17, 18) of the heated medium. Parallel glass strips are placed inside each tube (11). Spaces cross-pieces maintain the neighbouring glass strips at a distance which corresponds to thickness thereof. The glass strips are slightly tinted so that they absorb only in part the radiation received. The absorption coefficient of the glass strips is about 0.1 allowing about 90% of the received radiation to come out of the glass strips and enter other glass strips. Hence, all of the received energy is distributed among the totality of the glass strips so that the glass strips are uniformly heated and there is no overheated spot on the glass strips. Heat of the glass strips is transmitted to the gaseous medium circulating between the glass strips inside the tube for evacuating the heat. This device is particularly appropriate for use in a tower of an helioelectric power-station wherein a multitude of minors arranged on the ground direct the solar radiation against the top of the tower.
(FR)Des tubes (11) en verre quartzeux sont disposes entre un dispositif (15, 16) servant a amener un milieu gazeux transparent et un dispositif d"evacuation (17, 18) du milieu chauffe. Des bandes de verre paralleles sont placees a l"interieur de chaque tube (11). Des entretoises d"ecartement maintiennent les bandes de verre voisines a une distance qui correspond a leur epaisseur. Les bandes de verre sont legerement teintees pour qu"elles n"absorbent que partiellement le rayonnement recu. Le coefficient d"absorption des bandes de verre se monte a environ 0,1 permettant a environ 90% du rayonnement recu de ressortir hors des bandes de verre et d"entrer dans d"autres bandes de verre. Ainsi, toute l"energie recue est distribuee dans la totalite des bandes de verre de facon que les bandes de verre soient chauffees uniformement et qu"aucun endroit des bandes de verre ne soit surchauffe. La chaleur des bandes de verre est transmise au milieu gazeux circulant entre les bandes de verre a l"interieur du tube pour evacuer la chaleur. Ce dispositif est particulierement utile dans une tour d"une centrale helioelectrique dans laquelle une multitude de miroirs disposes au sol dirigent le rayonnement solaire contre le sommet de la tour.
