Fabric filter at thyssenkrupp sinter plant makes progress

Since 2011, thyssenkrupp Steel has invested a total of around EUR 100 milion in a fabric filter project at its Duisburg site to clean the air from the sinter plant. The last of three fabric filters is scheduled to go into operation in spring 2020. In the course of the project another section of the filter has now been moved into position: with a weight of 17 tons, it took two 80- and 220-ton cranes to do the job.

The creation of dust in the sintering process is unavoidable, and electrostatic precipitators usually collect mostof this dust. thyssenkrupp claims it is setting new standards in air cleaning with its large fabric filters and collecting even the smallest dust particles.

The sinter plant in northern Duisburg consists of three belts. A fabric filter for the smallest belt has been in operation since 2011. The filter unit on the largest of the three belts was commissioned in 2017. Now it’s time for belt number three. “The fabric filter system in Duisburg is among the biggest and most effective of its kind in the world,” says project manager Tibor Hänsel. (thyssenkrupp)
