The control algorithm includes two different methods of adding reagents. First, the reagent is coarsely adjusted according to the solid content in the feed and the reagent consumption per ton of coal; And then it is finely adjusted under the control of the Fuzzy Logic Algorithm according to the ash content of the clean coal. The industrial experiments and the site application show that this control model can keep a stable ash level of clean coal and cut down obviously the reagent consumption.展开更多
