摘要

A process for the utilization of ashes with a high coal content of coal dust furnace installations,the carbon-containing ash according to a separation of coarse constituents an eddy layer is applied. the sorter, in which, with a liquid is a fluidized bed is produced and the charging material into a withdrawn at the upper side of the fluidized bed of high fraction with a high proportion of carbon particles as well as a drawn off at the bottom ash fraction is separated decarburized,the decarburized ash fraction, and is dewatered on a vibrating sievethe sub-sieve fraction in a hydrocyclone according to be cleaned and in the hydrocyclone separated solids are fed onto the vibrating screen.
