The new 3.75 MW biomass plant is connected to the existing natural gas-fired boilers and heat pumps

The new plant from Linka Energy will in the future cover approximately one-third of the heating demand in Tønder.

The price of biomass is highly competitive compared to the price of natural gas, and with a wood chip-fired plant of this size, sustainability is ensured. Therefore, the new wood chip plant contributes to securing both robust energy prices for consumers and a future-proof facility.

In addition to economic savings for the heating plant and consumers, the new wood chip plant will result in an annual reduction of approximately 4,100 tons of CO2 emissions.

The plant

The plant consists of a 3.75 MW Linka biomass boiler with flue gas condensation, developed and optimized in close collaboration with Linka Energy’s suppliers.

Particles (mg/m3): < 0,9 (Limit value: 30)
CO (mg/m3): 224 (Limit value: 750)
NOx (NO+NO2) (mg/m3): 205 (Limit value: 300)
O2 (vol. - %): 4,2
Water vapor content (vol. - %): 8,7
Volume flow (m3 (n,t)/h): 4.750
Flue gas temperature (°C): 44,9

The wood chip firing is done via hydraulic pistons – a technology developed in collaboration with specialists from Linka Energy’s Swedish subsidiary, Jernforsen Energy. This, combined with Linka Energy’s globally patented combustion technology, ensures Tønder Fjernvarmeselskab (Tønder District Heating) a future-proof sustainable biomass-fired plant with high efficiency.

The fully automated, state-of-the-art heating plant is designed to ensure stable operation with a focus on user-friendliness and a good working environment for operating personnel. The manpower requirement is minimal, and the plant can even be monitored remotely, meaning that consumers always have access to heat.
