Type of CHP system: Grate fired boiler
Status of plant: Commercial
Boiler unit: BWE
Turbine unit: Siemens
Boiler feed pumps: KSB
Boiler unit: Steinmüller
Turbine unit: ABB
Boiler feed pumps: KSB
Power generation: Steam turbine
High efficiency due to co-production of electricity and district heating (no summer-cooling). Dioxin filters have been installed since erection.
Main fuel: MSW
Unit 1: Waste capacity: 2×8 tonnes/h. Input capacity 2×23,5 MW
Unit 2: Waste kapacity 1×16 tonnes/h. Input capacity 1×60 MW
Nominal capacities & efficiencies:
Thermal input, biomass & waste: 106 MW
Total thermal input, incl. fossil fuels: 106 MW
Gross electrical output: 29,4 MWe
Net electrical output: 24 MWe
Heat output: 64 MJ/s
Electrical efficiency, gross: 27,7 %
Electrical efficiency, net: 22,6 %
Overall efficiency, gross: 89,7 %
Power to heat ratio:
Unit 1: 0,345
Unit 2: 0,40
How is plant controlled: Controlled by the amount of waste that has to be disposed
Heat backup: No such installations
Heat usage: Heating only
The power produced is fed into the electricity grid.
The heat is supplied to the district heating system.
DH inlet temperature: 85 °C
DH return temperature: 45°C
Heat storage size: None m3
Hours of full load that the heat storage can meet: 0
Fuel storage: Max capacity in bunker: 3000 tonnes
Waste water generated: 26.500 m3/year. 18.250 from HCL-scrubber goes to municipal treatment. 8.250 from SO2-scrubber to re-use in Elsam wet fluegas-cleaning on coal-fired plants.
Ash discharge: Fly-ash goes to refilling of saltmines. Bottom-ash goes to reuse under roads, buildings etc.
The idea of the plant is to reduce waste to energy (electricity and district heating) and at the same time to produce as little polution as posible.
Unit 1 commissioned in 1996. Unit 2 in 2000.
Fuel feeding system: Waste from bunker via cranes to hubbers.
Boiler: Moving grate fired waste boiler
Turbine: Back pressure turbine
Unit 1: 56,99 t/hr
Unit 2: 78,12 t/hr
64 bar/380 oC
Flue gas cleaning:
Unit 1: Electrostatic filter, wet two-stage scrubber, end of the line dioxin-filter, baghousefilter.
Unit 2; HOK-injektion, hot baghouse filter, wet two-stage scrubber
Cooling system: Cooling by district heating water
