Waste Heat

Approximately one fifth of the global energy consumption is used for industrial process heat. Even though some of this heat is used for the products themselves, a large portion of this energy remains unused.

Smallest electrical power output of our waste heat recovery equipment

Typical industries that generate waste heat are:

  • Steelmaking
  • Cement manufacturing
  • Glass production
  • Refineries
  • Chemical plants
  • Ceramics Manufacturing
  • Copper production
  • Aluminium production
  • and many others...

Commonly waste heat from before mentioned processes is available as warm water with temperatures around 100°C or low pressure water steam. These heat sources can be utilized with our screw expander low temperature units.

For waste heat that comes from hot exhaust gases with temperatuers exceeding ~200°C we offer our high temperature turbine units. With a thermal oil cycle the heat from the exhaust gases can be collected even from multiple sources and transported efficiently to our turbine ORC-systems.
