Title (EN) HYBRID SOLAR POWERED STIRLING ENGINE
(FR) MOTEUR STIRLING HYBRIDE À ÉNERGIE SOLAIRE
Abstract:
(EN) A hybrid energy conversion system comprising a sun concentrator, a radiation chamber configured to receive high density sun radiation from the sun concentrator, and a Stirling engine operable to convert the high density sun radiation into mechanical energy. The system further comprises a burner arranged to use the radiation chamber as a combustion chamber for combustion of a suitable fuel for operation of the Stirling engine, and an enclosure forming an intermediate space between the enclosure and the chamber. A pressure in the intermediate space is kept higher than a pressure in the radiation chamber. The flow of air through the intermediate space surrounding the radiation chamber will serve to remove any heat escaping from the radiation chamber. Thus, hot spots can be avoided, thereby reducing the risk for leakage caused by such hot spots.
(FR) L'invention concerne un système de conversion d'énergie hybride, lequel système comprend un concentrateur solaire, une chambre de rayonnement configurée de façon à recevoir un rayonnement solaire de haute densité à partir du concentrateur solaire, et un moteur Stirling pouvant fonctionner de façon à convertir le rayonnement solaire de haute densité en énergie mécanique. Le système comprend en outre un brûleur agencé de façon à utiliser la chambre de rayonnement comme chambre de combustion pour la combustion d'un carburant approprié pour le fonctionnement du moteur Stirling, et une enceinte formant un espace intermédiaire entre l'enceinte et la chambre. Une pression dans l'espace intermédiaire est maintenue plus élevée qu'une pression dans la chambre de rayonnement. L'écoulement d'air à travers l'espace intermédiaire entourant la chambre de rayonnement servira à éliminer toute chaleur s'échappant de la chambre de rayonnement. Par conséquent, les points chauds peuvent être évités, permettant ainsi de réduire le risque de fuite provoqué par de tels points chauds.
