Abstract
A process is described for avoiding the formation of highly condensed aromatic hydrocarbons and dioxines in combustion systems, preferably in garbage incinerating systems, wherein the combustion exhaust gas are dedusted at temperatures from 300.degree. to 1000.degree. C. behind the furnace and wherein said process combustion exhaust gases are dedusted by means of a ceramic filter element which is made of SiO.sub.2 and/or Al.sub.2 O.sub.3 and/or ZrO.sub.2 and an inorganic binder and has a porosity of 50 to 90% and an apparatus for carrying out the process is also described.
