ABSTRACT:
The invention relates to a method of flue gas abatement for a combustion process, particularly for a refuse incinerating unit, in the case of which ammonia in a gaseous form or dissolved in water is fed into the combustion process or hot flue gases therefrom and furthermore preferably acidic components are removed by scrubbing from the flue gases and are neutralized by a basic material, to which milk of lime has been added, and furthermore the flue gases may be passed in addition though adsorbing materials and if necessary basic materials are supplied to the process so that nitrogen oxides, hydrogen chloride in gas form, dioxines and furans are removed. The material necessary for this are taken from a local sewage plant where they at least proportionately form partial streams in a sludge treatment unit and otherwise would have to be dispensed with.
