Description
The Wärmelieferungsgenossenschaft Fürstenschlag e.G. Altdorf (WLG) has been supplying around 440 customers with district heating for more than 30 years. The district heating network has a length of approx. 7,500 meters. The heating plant is located on the edge of the residential area and has a heating load of approx. 5 MW with an annual demand for useful energy of approx. 6300 MWh. The base load requirement is covered by the new natural wood biomass boiler with a nominal heat output of 800 kW. Three existing oil-fired boilers are currently available for the peak load. Following economic feasibility studies and system optimization, one oil boiler can now be permanently switched off and replaced by the biomass boiler.
