Abstract

L'invention concerne une centrale électrique améliorée équipée d'un système de recyclage des gaz chauds à base de CO<SUB>2</SUB>, le CO<SUB>2</SUB> étant recyclé à haute température à l'issue du processus de combustion. La centrale électrique selon l'invention présente deux améliorations par rapport aux types de centrale connus. D'une part, l'échangeur de chaleur gaz de fumées/air a été adapté aux exigences de la membrane haute température et la connexion avec ladite membrane a été réalisée de sorte que les gaz chauds et l'air traversent à présent ces éléments à contre-courant. Les gaz de fumées chauds traversent d'abord la membrane et sont ensuite refroidis dans l'échangeur de chaleur, tandis que l'air est d'abord chauffé dans l'échangeur de chaleur, puis il atteint la membrane avec une température suffisamment élevée. Les températures de gaz dans la membrane sont sensiblement constantes et les différences de température entre les gaz de fumées et l'air dans la membrane sont réduites de façon avantageuse. Cette connexion permet de créer dans le circuit de gaz chauds une zone présentant une température d'environ 500 °C considérablement réduite. Le déplacement de la position de la soufflerie de recyclage dans cette zone permet de résoudre les problèmes qui empêchaient jusqu'à présent la réalisation d'une soufflerie à gaz chauds.
