Aalborg Energie Technik a/s - Biomass Cogeneration Plant
Østkraft supplies power and district heating to the habitants of Bornholm. The boiler (Block 6) was built in 1996 and was built from the start with the possibility of using 20 % biomass in the combustion process. Østkraft decided in 2013 to convert the plant in order to be able to use 100% biomass, without losing the flexibility and possibility of utilising coal and oil, if necessary. This flexibility is essential, as Østkraft is situated on an island. The plant must be ready to start the oilburners quickly in case the power cable to Sweden should be damaged.
The plant has been retrofitted in autumn 2016 with AET Combi Spreaders.
