Thyssenkrupp Steel Europe will upgrade the combustion system of its hot-dip galvanizing line FBA 8 in Dortmund.
The order for delivery, assembly and commissioning of 195 modernised self-recuperative burners has recently been placed with WS Wärmeprozesstechnik. The newly implemented heating system will provide drastically lower emissions, Kallanish learns from the supplier company. It claims that the heating system will achieve exceptionally low NOx emissions due to a proven double P-tube design and its patented “Flox” combustion process. The retrofit is to be completed by mid-2022.
The order complements the construction of an all-new galv line next to FBA 8, which is projected to start operating this year. Together with another colour-coating line, up to 2 million tonnes of coated strip will then be processed annually in Dortmund. According to WS, the technology employed is suitable for a future with green combustion gases. After the conversion, approximately 800 low emissions burners will be in operation at the Dortmund facility.
WS aims at providing “solutions for all continuously operated strip lines which can reliably attain NOx emissions well below 100 mg/Nm³, with simultaneously high combustion efficiency over 80%”, says company president Joachim G. Wünning.
