Process for the thermal disposal of high-calorific fractions from sorted waste and / or residues in fossil-fired power plants, especially lignite-fired power plants with wet flue gas desulfurization

摘要

The invention relates to a method according to 19925011.1-13 for the thermal disposal of high-calorific fractions from sorted waste and / or residues in fossil-fired power plants, in particular lignite-fired power plants with wet flue gas desulfurization. DOLLAR A The object of the invention is to partially or completely free the coke formed in the pyrolysis of pollutants, in particular chlorine, and to dispose of the resulting waste products in a residue-free and environmentally friendly manner. DOLLAR A This is achieved according to the invention in that the coke formed in the pyrolysis from waste and / or residual material in a scrubber, in particular in a single-stage and / or multi-stage water and / or process water of a water bath and / or an immersion bath and / or or a jet bath freed of pollutants, especially chlorine, in a proportion of = 50% and then the chlorine-reduced coke is fed to a conventional combustion process of a downstream steam generator and the washing water which is created in the scrubber and contains about 100 g / l of chloride is added to the water generated in the power plant process Flue gas desulfurization water is added in an amount of approx. 5% to approx. 10% and spent together with the steam ash as a stabilizer on the landfill.
