    Abstract: A description is given of a method as well as an apparatus for heat treatment of raw materials such as cement raw meal, limestone or other mineral-containing raw materials, by which method raw material is preheated and possibly calcined in a preheater system (1) and possibly burned in a kiln (8), and where solid and/or liquid fuel is brought into contact with preheated raw material in the presence of steam in a gasification reactor (3) thereby causing the fuel to be fractionated partly into a hydrogen-containing combustible gas which is discharged from the gasification reactor via a gas outlet and partly into carbonaceous solid fuel residues which are discharged from the gasification reactor via a solids outlet. The method and apparatus are characterized in that at least some of the hydrogen-containing combustible gas is utilized for heat treatment of raw material.

    Abstract: A description is provided of a method and an apparatus for manufacturing of cement whereby cement raw meal is 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. The method and the apparatus are peculiar in that 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 being subsequently recirculated to the calciner, and in 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 in the underground or other additional treatment.
