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 process the flue gas in the flow direction downstream of the furnace bromine and / or bromine-containing compounds are added and subsequently the flue gas at least one dry cleaning for the separation of the mercury and about excess bromine and / or is subjected to excess bromine compounds. The method according to the invention is characterized in that the bromine and / or the bromine compounds with the flue gas in the case of a flue gas temperature between 80°C. and 490°C, preferably between 80°C. and 250°C. are brought into contact.
