Nordforbrænding: Hørsholm, Denmark Waste-to-Energy Plant - Case study


Courtesy of Dürr MEGTEC, LLC

The plant Nordforbrænding is owned by five municipalities (Hørsholm, Allerød, Fredensborg, Elsinore, and Rudersdal) in the northern part of Zealand in Denmark covering a population of approximately 200,000 inhabitants. Nordforbrænding contracted a new waste-to-energy line to be completed in 2016.

The new waste-to-energy line will be based on our NextBAT® technology securing a very high energy recovery and very low emissions. The R1 value is actually more than 100% above the threshold value of 0.65. After completion of the new furnace line 5 in August 2016, the plant will produce heat and power from line 4 and 5 only and replace the existing three worn down B&W Vølund lines from 1969 and 1989. The existing furnace line 4, from 1998, will remain in operation.

The new line 5 naturally fulfills all requirements that will be presented in the coming waste incineration BREF in 2013. This is the core of our NextBAT®technology.

Nordforbrænding is located in the middle of Hørsholm, an affluent northern suburb of Copenhagen, and has been accepted by the neighbors as a good solution to waste management and energy supply.

Facts: New furnace line at Nordforbrænding

  • The new combined heat- and power-producing wasteto-energy line shall be designed for burning 10 tonnes of waste per hour and operate independently from the other lines. Steam data are 50 bar/400 ˚C.
  • The plant’s energy efficiency will increase from its current level of 70% to 99% in the future.
  • Together, furnace lines 4 and 5 will still be able to process 152,000 tonnes of waste annually.
  • With the new furnace line, Nordforbrænding will be able to produce double its production of electricity and 30% more district heating.
  • The plant’s electricity production will reach 80 GWh/year, corresponding to the electricity consumption of 15,000 detached houses.
  • The plant’s heat production will reach 370 GWh/year, corresponding to the heat consumption of 25,000 detached houses.
  • The new boiler can process several types of fuel other than waste, such as biomass and sludge. This means that the plant is future-proof and can be used for energy supply and waste treatment in several ways.

Babcock and Wilcox Vølund will supply;

  • Our DynaGrate® is unique in its fuel flexibility, optimised combustion and minimal maintenance costs.
  • A multi-pass boiler.
  • VoluMixTM forms a complete burnout in the gas phase by injecting air into the combustion zone.
  • An ash treatment system.
  • An advanced NOx treatment technology.
