Switch to biofuel has proven a good investment for Tversted Heating Plant.

In 2015 Linka installed a wood pellet system at Tversted Heating plant. As one of the most expensive heating plants in Denmark, the switch to a biomass plant has already proven a good investment.


Before installing the new biomass plant, Tversted Heating plant was one of the most expensive heating plants in Denmark, making it difficult to offer customers competitive heating prices. A settlement behind the Energy Agreement of 2012 enabled the plants switch from gas to biofuel.

Since Tversted is already using solar heating, they need a wood pellet system as a supplement to this, making sure the area is well supplied all year round.


Since Tversted Heating plant is located within a residential area they were not able to expand the existing buildings. Therefore a wood pellet system, which takes up less place than other plants, was the optimal solution.

To accommodate a possible switch of fuel in the future, the system was prepared for wood chips.

The solution

Linka installed a 1,000 kW hot water system with automatic supply of wood pellets from a mine with a scraper unit. An economizer was added to the system, to subtract extra heat from the flue gas and hereby increase the plant’s efficiency.

By adding a bag filter the flue gases are cleaned and dust from the plant is reduced.


Customer: Tversted Heating Plant
Fuel type: Wood pellets
Plant size: 1,000 kW
Plant type: Hot water plant
Energy type: District heating


CO concentration: 32 mg/m3

The CO emissions from the plant are well below the environmental demands for 400.
