Tasks

At the Ibbenbüren location, coal is milled and burned to generate electricity, which generates pyrite, consisting of unground and ground coal and rock. If a mill is turned off, the unground mixture of fuel and rock remains in the mill, which has already led to considerable damage to the coal mill. In the future, the remaining mixture of coal and rock remaining in the mill will be cleared out of the mill within 20 minutes. Previously, this was not possible due to the storage volume of the existing containers. Therefore, this location had to be equipped with new, larger pyrite tanks along with new MSR (instrumentation and controls) technology. As part of this measure, a conversion of the existing pyrite facility from ABB Contronic 3 to ABB Melody took place at the same time. The above-referenced procedural changes, including a new operating mode of the mill, were implemented directly in the new automation of the AC870P controller (Melody). The Maestro UX control system has been retained. As a result, the affected operating screen changes were adapted and the connection of the new MSR components was established in the AC870P controller.
