  • Process for the thermal treatment of solids which arise in the purification of flue gases
    Patent number: 5501161
    Abstract: Dustlike and/or finely divided solids which arise in the purification of flue gases, in particular from refuse incineration plants, are subjected to a thermal treatment. In this case, the said solids are fed to a filter device along a predetermined transport path by a gas stream having at least the thermal treatment temperature. After the filtration, the solids can be subjected to a thermal post-treatment. The thermal treatment can serve to destroy halogenated, in particular aromatic, hydrocarbons, to remove ammonia or other volatile constituents.
