Abstract
An object of the present invention is to separate COgas generated in a cement-manufacturing facility in a high concentration and recover the COgas. The present invention includes: feeding a cement material before calcination and a heat medium which has a particle diameter larger than that of the cement material and has been heated to the calcination temperature or higher in a medium-heating furnace (), to a mixing calciner (); and recovering the COgas generated by the calcination of the cement material. The heat medium circulates between the medium-heating furnace and the mixing calciner. Another aspect of the present invention includes: feeding a cement material before calcination to a regenerative calciner () which has been heated to the calcination temperature or higher and has stored heat therein; and recovering the COgas generated by the calcination of the cement material.
