A method for burning raw materials by which method the raw material and a secondary fuel are separately introduced to one and the same rotary kiln in which the raw material as well as the secondary fuel are heated by gases formed by burning of a primary fuel in the rotary kiln so that the secondary fuel is converted to gases and solid matter in the form of combustion residues such as ashes and coke. The secondary fuel during the process of conversion to gases and solid matter is kept separate from the introduced raw material, which may ensure that the secondary fuel and hence the locally reducing zones and major areas with reducing conditions are brought into minimum contact with the raw material.
