Eidsiva Bioenergi has started work on the construction of a new energy plant which is fired with wood chips from demolished buildings, so-called RT wood chips. In Kongsvinger, which is situated north-east of Oslo, waste wood from local buildings will be used in future to produce district heating for the town’s citizens.
“The wood chips 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,” says Bo Johansen, Sales Director at Verdo.
The waste wood usually comes from the local area. Therefore, you also eliminate the transport costs related to disposal of the waste wood, and instead use the wood to supply district heating to people’s homes and hot water to their taps.
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 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,” says Bo Johansen.
The energy plant has a power output of 8 MW, and will supplement heating supplies in Kongsvinger. The plant has been developed in a 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.
