Verdo Energy A/S, a subsidiary of Denmark-headed renewable energy utility and technology developer Verdo A/S has recently revealed that it has been selected by Eidsiva Bioenergi AS, a subsidiary of Norwegian energy utility Eidsiva Energi AS, to design and build an 8 MWth biomass-fired heat plant in Kongsvinger, Norway. The plant will use recycled wood including from construction and demolition waste (aka RT-chips) as fuel.

According to Verdo, Eidsiva Bioenergi has started work on the construction of the new district heat plant in Kongsvinger, which is situated north-east of the capital city Oslo. There has been a lot of focus in recent years in Norway on how to recycle this waste timber from the construction industry.
The woodchips contain, among other things, paint residues and parts from building installations, which is why the plant is designed to handle the emissions and slag that result from the combustion process. This requires special technology, one that takes into account the emissions and non-combustible residual waste, said Bo Johansen, Sales Director at Verdo.
High-spec technical solution
Eidsiva Bioenergi has obtained special permission to build the plant and has subsequently specified that it must comply with the stricter requirements which apply when building near residential areas. This demanded a lot of the technical solution.
There are stricter rules in place covering noise and emissions from an energy plant which is built near a residential area. The energy plant is designed according to the latest advances in the furnace and grating technology in order to meet these requirements. Among other things, the flue gas is scrubbed extra clean before it is discharged, and the plant also incorporates a number of noise-reduction technologies, revealed Bo Johansen.
The energy plant has a power output of 8 MW thermal and will supplement heating supplies in Kongsvinger. The plant has been developed in close collaboration between Eidsiva Bioenergi and Verdo. All the buildings are made of wood so that the plant blends into the local area.
The project was launched in the spring and is expected to be completed for the upcoming heating season in the autumn. The plant will be unmanned some of the time, while technical personnel will man the facility during normal working hours. It will be remotely monitored during the evenings and at weekends.
