technical data:
generating heat and electricity; wood-fuel
•
Water-cooled vibration grate for biomass with a heating power of
26.7 MW; steam parameters: temperature 450°C, pressure 6 MPa (60 bar)
•
Two steam boilers with a capacity of 10.5 respectively 21 MW heating
power for supporting biomass-furnace during high loads and to ensure safe
heat delivery. Main fuel: gas.
•
Yearly heat production: 120 GWh
•
Steam turbine: 7.5 MVA; expected amount of electricity per year: 42 GWh.

Wood-fuel: total consumption 80,000 tons/a
within a radius of 40 km
100% natural wood and bark
technical data:
delivering steam, heat and chill
•
Steam conducting pipe to a producer of baby-food (HIPP):
length 950 m; Steam parameters: temperature 180°C, pressure 12.5 MPa
•
District heating for more than 150 customers between 15 and 3,500 kW:
- High-temperature net; length 14.5 km at a max. temperature: 130°C
- Medium-temperature net; length 4.5 km at a max. temperature: 85°C
- Low-temperature net for neighbouring customers (still under construction)
•
Cooling:
- One Li-Br absorption chiller (8/13°C) for a hospital; cool-capacity: 300 kW
- One Li-Br absorption chiller (6/14°C) for the basic demand of cold in two
business-buildings; cool-capacity: 700 kW.
- One NH3-absorption chiller (-6/14°C) in combination with an electric pistoncompressor-chiller (2 x 125 kW) for high loads and for low temperature
applications of a brewery during night and for air-conditioning of several
business-buildings by district-cooling during daytime: cool-capacity: 650 kW
