Aalborg Energie Technik a/s - Biomass Cogeneration Plant
The original CHP plant was built in 1982 and has provided Randers city with electricity and district heating for more than 20 years. The plant was originally commissioned as a spreader stoker coal-fired plant by Aalborg Industries.
In 2002-2003 and 2007-2009, two retrofits were carried out by AET:
In 2002-2003, AET retrofitted the cogeneration plant with an AET biomass dust-firing system. The plant was then able to operate in co-firing mode with min. 50% coal and max. 50% biomass fuel or 100% coal in single mode - and any combination in between.
The biomass fuel system was designed for a variety of granulated biomass products such as meat and bone meal (MBM), olive stones, shea nuts, sunflower pellets, biopellets and others.
In 2007-2009 a substantial retrofit was carried out by AET enabling the plant to fire 100% biomass or 100% coal or any combination in between e.g. 70% biomass and 30% coal. This is possible with the AET Combi Spreader Stoker.
A redesign of the two boilers was caried out, taking into account the narrow available space. The CHP plant is now able to burn uncontaminated wood chips as well as dusty fuels.
AET handled the retrofitting of the two boilers as a delivery consisting of:
