    Abstract: A method and an apparatus for manufacturing of cement includes cement raw meal being preheated in a preheater, calcined in a calciner by contact with hot gases which are introduced into the calciner via a gas inlet and being diverted from the calciner via a gas outlet, and where calcined cement raw meal is diverted from the calciner, burned into cement clinker in a kiln and subsequently cooled in a clinker cooler. At least a portion of the calcined cement raw meal diverted from the calciner is heated further in a separate system to a temperature which exceeds the calcination temperature and is subsequently recirculated to the calciner. That at least a portion of the gases which are diverted via the gas outlet of the calciner is removed from the plant with a view to storage underground or other additional treatment.
