Bad Sooden-Allendorf, Germany
Operational since 2011
.
A biomass heat plant was installed in the Rhenanus school in Bad Sooden-Allendorf, and the existing heat distribution systems were renovated. Approximately 80% of the energy required for heat generation is provided through locally sourced untreated forest wood chips. This results in the replacement of approximately 100.000 liters of heating oil per year with wood from the region.
In a separate small heating house (with a construction volume of 360 m³), a biomass combustion system with a boiler capacity of 350 kW and a pre-installed fuel storage for wood chips was installed. A new peak load boiler was also installed in the new heating center. It is operated with heating oil during winter to cover peak demand and during the summer months for partial or low-load operation. The delivered wood chips are stored in a push floor system with fully automated discharge (storage volume of approximately 150 m³). The integration of the boiler system into the existing pipeline network is done through a district heating pipeline. A multi-cyclone and an electrostatic precipitator are used for flue gas dedusting, ensuring compliance with legal emission limits.
