摘要： A method and system for purifying flue gases from power plants fired with fossil fuels has an absorber with at least one contact installation level arranged in an upper region, impinged with a suspension, and flowed through by untreated gas. The lower region has an absorption suspension sump, above which the inflow for the untreated gas is disposed. A separate reaction container includes two chambers separated by a partition wall with an overflow. The first chamber is connected with the sump, receives oxidation air, and has in a lower region an opening for discharging suspension. The second chamber is connected with a lime/limestone suspension container. A gas exhaust hood above the reaction container draws exhaust vapors into an exhaust vapor hood. A line for absorption suspension extends between at least one spraying level of the absorber and the reaction container, and a process water feed lies above the spraying level.

摘要： A process for cleaning the surfaces of interior parts of two-stage flue gas desulfurization plants, which employ limestone as absorbent to form gypsum as the final product, such as guide plates and baffle plates and/or the discharge pipe and the bottom side of the feed hoppers, said interior parts being contacted by flue gas stream(s) and liquid absorbent. The process is characterized in that the parts and/or areas of said interior parts to be cleaned are washed periodically with process water or first with a portion of the absorbent suspension of the upper absorbent circulation and then with a portion of the process water.

摘要： A method and apparatus for wet flue gas desulfurization in a two-circuit washer having two washers for an absorption agent based on suspensions containing calcium compounds, a sump for supplying the absorption agent to the first washer, and a container for at least partial recovery of the absorption agent from the second washer. The absorption agent, while being returned to the container, is actively brought into contact with oxygen to oxidize calcium sulfite to calcium sulfate. The return line has apparatus for actively blowing in oxygen with only a relatively slight overpressure necessary to blow the air into the absorption agent. The absorption agent to be oxidized is already moving because the difference in elevation along the return line from the recovery apparatus to the container, whereby the absorption agent then arrives more or less completely oxidized.
