Environmentally friendly district heating from waste heat

Steel billets are heated to 1,300 degrees in the rotary hearth furnace to turn them into seamless high-tech tubes. This process generates a lot of waste heat, which until now could not be used to its full extent. Thanks to an innovative, cross-industry and partnership-based cooperation between the bioenergie.at group of companies and voestalpine Tubulars, environmentally friendly district heating can now be made available for Kindberg. 

With the concept of the waste heat specialists from Köflach, up to 4,000 kW of waste heat can be extracted from this process. In detail, a dedicated heat exchanger with 1,536 water-bearing pipes will be installed upstream of the special chimney to be built for heat recovery. Via a dedicated pumping station on the premises of voestalpine Tubulars, the heat thus obtained will be made available to the new district heating network of the Kindberg municipality.
