Even more biomass
Our power plant portfolio also includes three wood-fired heating plants. In these, we utilise green waste, unusable residues from forestry and non-critical waste wood, such as pallets or packaging boxes. We use this wood in shredded form - as woodchippings - so that the plants function automatically except for filling the fuel store. This means that no forest wood is felled for our systems.
Three wood chip heating plants are now in operation. These generate as much heat as 500 modern single-family homes need per year.

How the heating plant works
Fuel store
A fully automatic crane transports the woodchippings from the fuel store into the hopper of the boiler.
Fuel into the boiler
From here, the fuel is fed into the boiler via two parallel-running screws, where it is burnt.
Combustion
The wood is burnt at approx. 850 °C and transported over a long grate to the fully automatic ash discharge system.
