METHOD FOR PREVENTING THE CONSTRUCTION OF HIGHLY CONDENSED AROMATIC HYDROCARBONS AND DIOXINES IN COMBUSTION PLANTS.

摘要

A process is described in which dust removal from the incineration waste gases is carried out downstream of the burners at temperatures of 300 to 1000 DEG C and in which compounds containing ammonia nitrogen are added to the incineration waste gases downstream of the burners in a temperature range of 400 to 1000 DEG C. In this process, dust removal is carried out on a filter element which is composed of SiO2, Al2O3 and/or ZrO2 and an inorganic binder and which has a pore volume of 50 to 90%. IMAGE
