Aalborg Energie Technik a/s Biomass Cogeneration Plant

ENGIE Cofely, Biolacq Energies, France

The Biolacq Energies project is a biomass-fired Cogeneration plant with an annual fuel consumption of 160,000 tonnes.

Biolacq Energies, which is a subsidiary of ENGIE Cofely, supplies steam to SOBEGI at the INDUSLACQ Industrial Park, a Seveco site.

 

The AET Biomass Boiler supplies steam to a high pressure turbine, which sends medium pressure steam to SOBEGI, as well as low pressure steam to an air cooled condenser.

 

The AET Biomass Boiler combusts forestry wood and uncontaminated residues from wood processing.

 

The use of wood energy prevents the release of 86,000 tonnes of CO2/year for the next 20 years. It produces 89 GWh of green electricity per year, which is equal to the power consumption of 13,000 homes.

 

Performance test

The performance of the AET Biomass Boiler was succesfully tested by Bureau Veritas in 2015:

  • Boiler efficiency: 93.5%
  • In-house power consumption: only 0.7% of the fuel heat input (359 kW)
  • Emissions well within the stringent French standards.

The plant was completed and commisioned in 2016.

 

AET designed, supplied, constructed and commissioned the following scope:

  • AET Fuel Dosing System
  • AET Combustion System with AET Spreader Stoker and AET Biograte
  • Oil burner
  • AET Biomass Boiler with superheaters and economisers
  • AET Combustion Air System

The AET Biomass Boiler at Biolacq Energies in France.

The Biolacq CHP plant was commissioned in 2016.

The wood comes from uncontaminated residues from the processing of wood.
