In Sweden, Solör Bioenergi Group, a leading Scandinavian player in renewable wood-based energy, has taken the next step towards cleaner air and safer district heating in Falköping. At its facility in Marjarp, a new dust filter has been put into operation, improving local air quality while creating future growth opportunities.
At the Marjarp industrial estate in Falköping, Solör Bionergi produces district heating for villas, apartment buildings, and industries.
The biomass fuel consists of chipped logging residues from the local area and clean wood waste from, amongst others, a joinery located close to the district heating plant.
Flue gases from the combustion of biomass fuels such as woodchips and bark contain variable amounts of particles that need to be removed.
The boiler in Falköping already meets the current environmental requirements, but after 25 years of operation, it was time to install a more modern and efficient flue gas filter.
The new filter removes more dust from the flue gases, thereby improving local air quality in Falköping.
The old filter was both worn and difficult to repair, so we chose to invest in a new one. The new filter not only meets today’s purification requirements, but is also dimensioned for a future expansion of the plant when the need for district heating increases, said Anders Tigell, Falköping Plant Manager.
Investing in the future
Emissions from industrial boilers are subject to increasingly strict air quality requirements. Solör Bioenergi is investing almost SEK 200 million (≈ EUR 18.3 million) to adapt its heating plants to the stricter emission regulations that come into force in 2030.
We are making this investment both for the sake of the environment and the future. The new filter means cleaner air for the residents of Falköping already today, and at the same time makes the plant ready to meet the demands and opportunities of the future. It is part of our long-term work to develop sustainable and safe district heating solutions throughout the region, said Nicklas Eld, Regional Manager at Solör Bioenergi Väst.
New truck scale ensures the right price
In connection with the installation of the new filter, a new truck scale has been installed, which is capable of weighing 24-meter-long vehicles.
When the fuel is delivered to us, we weigh the truck both upon arrival and after unloading to determine the weight of the fuel. The assortment is also recorded. After that, we measure the moisture content to calculate the energy content of the fuel; different assortments have different heating values. This forms the basis for pricing, explained Anders Tigell.
With the renovation, a new site entrance has been built. This improves the traffic flow and makes it easier for trucks to enter the area.
