Oxy-fuel combustion is a combustion process in which the combustive is pure dioxygen and not air.
Advantage of oxy-fuel combustion
This process has the advantage of increasing the combustion temperature and therefore the energy released, and of producing smoke consisting of water vapour and concentrated carbon dioxide (over 80% of the volume).
Oxy-fuel combustion therefore facilitates the capture of CO2 and the production of concentrated carbon dioxide for industrial uses or geological storage.
This process of capturing CO2 is still in the pilot project stage, such as the Lacq project in France
