HyBeSt – Hybrid Heating in the steel industry

Initial situation

  • Optimal use of renewable energy in industry poses major challenges to production flexibility.
  • Synchronizing fluctuating energy supply and continuous production processes and quality requirements requires new approaches.
  • Flexible use of electrical energy at thermoprocessing plants is increasingly in demand.

Project goals

  • Development of a flexible, hybrid (fuel gas/electricity, preferably from renewable sources) heating solution for thermoprocessing plants.

Innovative approaches

  • First-time combination of fuel gas heating with electrical resistance heating in a hybrid radiant heating tube.
  • Flexible use of the above energy sources in a heat treatment furnace in the steel industry.
  • Use of the existing outer geometry of the radiant heating tube.
  • Burner technology is simultaneously prepared for future operation with hydrogen or green fuel gas.

Possible benefits for the industry

  • Energy-flexible heating of the thermoprocessing plant enables the use of different energy sources, depending on the cost situation, availability or grid efficiency.
  • Marketing of energy flexibility as well as avoidance of CO2 emissions.
  • Easy replacement of existing technology due to identical dimensions of the new system.
