Abstract

La présente invention concerne un système destiné à réaliser une combustion enrichie en oxygène au cours d'un processus industriel, le processus industriel, un système d'alimentation en oxygène ou une source d'oxygène, un réseau de récupération de chaleur, et un système à cycle de Rankine alternatif basé sur un fluide de travail autre que la vapeur étant intégrés pour permettre d'obtenir un meilleur débit et une plus grande efficacité. L'invention concerne également un procédé de combustion enrichie en oxygène dans un processus industriel utilisant ledit système. Des exemples de processus industriels comprennent la production de ciment, des applications de réchauffage de l'acier, la production de verre, la fusion d'aluminium et de cuivre, ainsi que tout processus industriel utilisant un appareil de production de chaleur industrielle, des fours dans lesquels la combustion est réalisée au moyen d'un flux oxydant présentant une teneur en oxygène supérieure à celle de l'air ambiant et allant jusqu'à 100 %.
