  • Publication number: 20170322545
    Abstract: Controlling a metallurgical plant, the plant has at least one plant part (1) operated with first and second operating parameters (BP 1, BP2) at a particular time, and an operating result (BE) is established on the basis of the operation of the plant part (1) according to the first and second operating parameters (BP1, BP2). The operating result (BE) is recorded. At least the operating result (BE) is transmitted from a control device (5) of the first plant part (1) to a computing unit (9). The computing unit (9) varies the second operating parameters (BP2), but not the first operating parameters (BP1), and thereby determines varied second operating parameters (BP2?) associated with the first operating parameters (BP 1). The computing unit (9) transmits the varied second operating parameters (BP2?) back to the control device (5) of the first plant part (1).

  • Publication number: 20160151733
    Abstract: A method for detecting a cleaning process in a plant having filters (1, 31) arranged spatially offset from one another, wherein a first gas (21) having solid particles (20) is conducted in a first flow direction (10) filtered by a respective filter (1, 31). To clean the respective filter (1, 31), a second gas (22) is conducted through the filter (1, 31) opposite the first flow direction (10). Then listen to noise produced in the filtering or other physical phenomena to determine a condition of the filter including if it is being cleaned. To detect a cleaning process in a plant, a respective noise (12) is detected by acoustic sensors (2, 32, 2?, 32?, 42) arranged spatially offset from one another during the cleaning of the respective filter (1, 31). Further disclosed are a system for detecting a cleaning process in a plant having such filters, and such a plant.
