INTEGRATED PROCESS FOR OXY-FUEL COMBUSTION AND PRODUCTION OF OXYGEN

摘要

Process for heating via oxy-fuel combustion in which a stream of air (21) is heated by means of at least one portion of the residual heat present in the fuel gases (11) discharged from the combustion chamber (100), at least one portion of said hot air stream (22) is introduced into an oxygen production unit (20) in which a portion of the oxygen present in the hot air stream (22) is extracted by means of one or more ITM, with a first stream of oxygen (50) at high temperature being obtained, said first stream of oxygen (50) is mixed with a second stream of oxygen (60) so as to obtain a total stream of oxygen (70) at a lower temperature than that of the first stream of oxygen (50), at least one portion of the total stream of oxygen (70) being transported to the combustion chamber (100) and used within as oxygen-rich oxidizer.
