A wood-fired heating system was installed to heat the Eslohe school center, which also supplies nearby properties such as the spa house, a senior care facility, and an indoor swimming pool with heat. Approximately 3.300 MWh of energy is provided annually through untreated wood chips, resulting in the avoidance of around 300,000 m³/year of gas. Approximately 700 tons of CO2 are saved each year. The investment volume, including the 1.2 km long district heating network, amounts to €1.29 million.
The fuel is stored in a covered push floor system. A scraper chain conveyor handles the further transport of the fuel to the grate combustion. The resulting grate ash and fly ash separated by electrostatic precipitator are disposed of in separate containers.
