摘要： The invention relates to a method and apparatus for burning raw material (3) including biomass-based and/or waste-based raw material in a combustion reactor (1) in such a way that the raw material is fed to the firebox of the combustion reactor, wherein the raw material is burnt. According to the invention, a calcium compound (4) is provided to the firebox partially or entirely in the form of calcium carbonate, the temperature and partial pressure of carbon dioxide in the gas atmosphere of the firebox are adjusted (5) during the combustion in such a way that calcination of the calcium carbonate is hindered and the maintenance of the calcium compound in the carbonate form in connection with the combustion is furthered, in which case the calcium carbonate forms a reactive bonding surface with alkali metal based substances, and the unwanted alkali metal based substances are conveyed (7) out from the firebox by means of the calcium carbonate.
