District heating is expected to provide a substantial share of the entire heat demand in 2050. Various heat sources, such as sewage water, surface water (sea, river and lake), industrial waste heat, geothermal water and flue gas, are used. However, some of these heat sources are causing fouling and/or clogging issues in the heat exchangers or heat pumps depending on their characteristics. Furthermore, surface waters cannot or can be limited used in the winter period (when the water is close to 0°C) because of the risk of freezing.

With the self-cleaning fluidized bed heat exchanger, fouling – organic and inorganic – as well as ice-scaling can be prevented. With the latter, extracting latent heat from water by freezing it will be possible.

Areas of application:

  • District heating and cooling with river and seawater
  • District heating with geothermal brine
  • Extracting latent heat from freezing surface waters
  • Heat Recovery from fouling liquid waste streams
