Abstract

L'invention concerne une centrale d'énergie (10) entraînée par turbine à gaz. Elle se compose de plusieurs éléments: un ou plusieurs compresseurs (20, 22) produisant un flux d'air en sortie; un échangeur thermique de compresseur (34) placé dans le flux des compresseurs (20, 22), cet échangeur thermique se poursuivant par une tubulure (50) convoyant une fraction latérale d'agent réfrigérant; un réchauffeur d'air (58) placé dans le flux de l'échangeur thermique et équipé de sa tubulure (50) convoyant une fraction latérale d'agent réfrigérant; une chambre de combustion (48) placée dans le flux du réchauffeur d'air (58); une ou plusieurs turbines (24, 28) placées dans le flux du réchauffeur d'air (58) et mécaniquement couplées aux compresseurs (20, 22); une turbine motrice (32) placée dans le flux des turbines (24, 28) couplées aux compresseurs. Les effluents de combustion s'échappent au travers de l'échangeur thermique (34) et la chambre de combustion (48). L'air fourni par les compresseurs (20, 22) s'échappe au travers de l'échangeur thermique et aboutit à la tubulure (50) d'agent réfrigérant puis au réchauffeur d'air (58). La chaleur de l'air dégagé par le compresseur est transférée aux effluents de combustion, ce qui produit un air de refroidissement et réchauffe les effluents de combustion. L'échangeur thermique (34) peut être, soit un échangeur thermique en tant que tel, soit un reformeur méthane/vapeur dégageant un effluent dilué dans la vapeur et à forte teneur en hydrogène et basse teneur en NOx. Dans d'autres réalisations, on produit plus d'énergie en injectant de l'air comprimé réfrigéré directement dans la chambre de combustion (48), ce qui a pour effet d'augmenter le volume circulant au travers des turbines (24, 28, 32), la chaleur d'évacuation étant récupérée par un flux à contre courant de combustible et d'eau (ou d'eau et d'air), au niveau d'une unité traditionnelle de récupération de chaleur (118) à circuit ouvert. Dans des réalisations futures, une petite proportion de l'air de refroidissement sera combinée à l'eau de récupération au niveau de l'unité de récupération de chaleur (188) pour favoriser la vaporisation de l'eau pendant toute la durée de la phase initiale du passage en échangeur thermique, ce qui provoquera la séparation en deux phases du mélange eau/air admis dans la chambre de combustion (48). En outre, dans toutes les réalisations, une partie de l'air comprimé réfrigéré peut être traitée par un compresseur/détendeur alimentant en fluide de refroidissement les turbines, les compresseurs et les équipements auxiliaires.
