Abstract
A method and reactor for processing fuels with a wide particle size distribution, particularly for flame combustion. The fuel is blown tangentially with the aid of an airflow into a swirl chamber containing a burning mass, thus creating a vortex, from the center of which a flow of material is led out of the swirl chamber. The vortex created by the feed of the fuel-air mixture and the diameter of the outlet flow are arranged to create a selective delay for coarse particles, so that the size of the particles is reduced, through mechanical treatment caused by evaporation, pyrolysis, and collision, to become smaller than the desired limit value, before they escape from the swirl chamber. The temperature of the cylindrical jacket of the swirl chamber is held below the melting point of the ash.
