Aalborg Energie Technik a/s Biomass Combined Heat and Power Plant

Swiss Krono Heiligengrabe, Germany

The Swiss Krono site contains a biomass-fired combined heat and power (CHP) plant that generates 20,000 kW of electricity and supplies the MDF and OSB manufacturer with heated thermal oil and supplies flue gas for the drying process.

Besides traditional wood chips, bark, sawmill residue etc. the plant has extensive experience of combustion using a wide range of A1 - A4 fuels:

  • MDF-granulate from chipboard manufacturing
  • Sander dust with very high N content
  • Composted wood with up to 25% ash/inert material
  • Fuel from external sources.

The plant utilises 130,000 tons of waste wood annually.


High Availability

The CHP plant was delivered in 2003, and had an availability of 95% (8300 hours) in 2013.
