AET's Service team has had the pleasure of optimising the performance of two out of four oil-fired boilers (K5 and K7) at the sugar factory at Nordic Sugar in Nykøbing F. (DK).
The individual performance optimisation, measured on the boiler outlet indicated:
- NOx reduced by 10-30% without use of SNCR
- Improving boiler efficiency by 0.5% and 1.8%
- Ammonia water consumption and NH3 slip are also reduced remarkably.
Nordic Sugar (part of Nordzucker group) therefore saves cost for oil, CO2 fee and ammonia water as well as they ensure that the emissions criteria can comply with future requirements, and it will further be possible to increase load in the boiler house.
The job has included changing critical design in the burners, introducing FGR and optimising the combustion and boiler operation. This was done during the sugar beet campaign.

Zignago Power - successfully producing green energy in Italy
The 49 MW AET Biomass Boiler at the cogeneration plant in Italy is owned and managed by Zignago Power, belonging to the Marzotto family empire, has since its installation in 2013 been running with a very high availability (98,8%). The plant utilises wood residues and agricultural waste such as straw, mischantus and maize
