A method for the deposition of mercury from flue gases from high-temperature installations

摘要

The invention relates to a method for the deposition of mercury from flue gases from high-temperature installations, in particular of power plants, and waste incineration plants, in which the flue gas in the flow direction downstream of the furnace reactants, for example, in the form of bromine or alkali metal sulfides are added and subsequently the flue gas at least one dry cleaning for the separation of the mercury and about excess reactant is subjected to, wherein said method is characterised in that the reactants and carbon-containing adsorbents in the form of activated carbons and / or added separately activated cokes the flue gas stream and that the reactants are output as a function of a preferably continuous measured concentration of mercury be metered into the flue gas stream.
