The hot-dip coating line 10 (FBA 10) of thyssenkrupp Steel in Dortmund was recently inaugurated in the presence of NRW Minister President Hendrik Wüst. The use of modern regenerative burners from WS Wärmeprozesstechnik GmbH in double-P radiant tubes typically saves 15% and 30% fuel, setting a global benchmark in energy efficiency and low-emission heating.
Thanks to the patented FLOX® process, particularly low NOx emission values are also achieved. The basis for a later switch to green fuels such as hydrogen is provided by the heating system, which has high efficiency and excellent temperature uniformity of the radiant tubes used.
Burner technology from WS Wärmeprozesstechnik
The thyssenkrupp plant in Dortmund, with its total of three vertical strip processing lines, is one of the world's most modern locations for the annealing and surface finishing of steel strip. Up to 2,000,000 tons of steel can be refined in the plants per year. WS has already supplied a total of almost 800 highly efficient and low-emission burners for the Dortmund site alone.
"It's the best technology available on the market, which we install to really future-proof the plant and still safely stay below emission limits many, many years from now," explains Dr. Clemens Trachternach, FBA 10 team leader, about the regenerative burners WS uses.
The multiple award-winning and patented FLOX® technology allows highly efficient burners to be operated with particularly low NOx emission values at the same time. WS has decades of experience with the technology, which is already successfully used in tens of thousands of burners worldwide. This enables the company to design future-proof analogs and keep emission levels low.
"Our claim at WS is to be able to offer solutions for all continuously operated belt plants that reliably achieve NOx values below 100 mg/Nm³ over a wide temperature range, while at the same time maintaining a very high combustion efficiency of over 80% and already equipped for green fuels of the future," says Dr.-Ing. Wünning, managing director of WS Wärmeprozesstechnik GmbH.
