摘要

A method for operating a flue gas desulfurization device for a brown coal dust fired power plant in which a suspension of burnt lime and sulfate used and the circulating water is enriched in the sump and the spray planes of a gas washer is placed and the ph - value of the suspension in the sump of the scrubber and in the lower spray planes by means of quantitative increase in the lime milk fraction in the suspension and the ratio of suspension / flue gas 6,5 greater so controlled in dependence upon the₂-Content of the flue gas is adjusted according to the german patent no. DE 195 02 632 C2, characterized in that the ph - value of the suspension to an upper limit value of less than 8,3 adjusted and controlled to the gas washer in the vicinity of the respective location - and / or installations specifically induced upper limit value is moved.
