World‘s largest coking plant produces with PROFIBUS and Ethernet
Here, the Schwelgern GmbH coking company belonging to the ThyssenKrupp Steel AG produces an annual 2.5 million tons of coke from coal for the neighboring large blast furnaces. The transformation takes place in a total of 140 of the world‘s largest coke furnaces with a capacity of almost 80 tons of coal each. In addition to coke, gas, tar and other carbon materials are also produced from the coal. ABB is responsible for the automation and uses Hirschmann™ field bus and Ethernet components for the automation.
For the automation of the coking plant, ABB chose a consistent networking of the system. The continuous data flow stretches from the control level to every single sensor. The system therefore defines the current state of the art with its size and the implemented environmental equipment. The degree of automation allows a fully automatic, unmanned furnace operation. The data networks for PROFIBUS and Ethernet signals are designed redundantly for the necessary operational reliability and critical connections are made by fiber optic cables.
