METHOD FOR ADAPTING AN INSTALLATION WITH A THERMOCHEMICAL CYCLE TO ALL TYPES OF OXIDES, AND INSTALLATION FOR IMPLEMENTING SAID METHOD

摘要

The invention relates to a method for adapting an installation with a thermochemical cycle for fuel conversion with capture of carbon dioxide to all types of oxides, said installation comprising a first loop (1, 1') with a fast fluidised bed that has a first oxidation reactor (1A, 1'A) and is associated with at least one first cyclone separator (1B, 1'B, 1"B) and a return line (1C, 1'C, 1"C) at the outlet of the first cyclone towards the first reactor, and a second loop with a fast fluidised bed (2, 2') that has a second combustion and reduction reactor (2A, 2'A) provided with a fuel introduction device associated with at least one second cyclone separator (2B, 2'B, 2"B) and a return line (2C, 2'C, 2"C) at the outlet of the second cyclone towards the second reactor, said two loops being interconnected by a first means (3, 3') for transferring oxides from the first loop to the second reactor and by a second means (4, 4') for transferring oxides from the second loop to the first reactor. According to the invention, the method involves extracting heat in a regulatable manner from the first oxide transfer means (3, 3') and from the second oxide transfer means (4, 4').
