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.

Background

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.

Considerations

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.
