摘要

The process for production of clinker, comprises preparing calcium oxide material by producing flue gases that are used for direct or indirect heating of a reactor (6) for decarbonation of calcium carbonate, and blending the calcium oxide material to form the clinker. The carbon dioxide is captured from the decarbonation reactor, and then recycled in the reactor. The recycled carbon dioxide is heated by the flue gas before reinjecting it into the reactor. An independent claim is included for an installation for production of clinker.
