Clean energy to benefit the environment
- Reliable operation of the installation 24/7
- Space-saving solution thanks to storage in bunkers
- Clean supply system without any emissions
- Automated blending operations ensure homogenous incineration rates
The power station in Hamburg-Lohbrügge
Facility concept shows the way
The use of scrap wood not only produces clean energy, but also offers high efficiency: CO2 emissions are reduced and stocks of fossil fuels are spared. An example for such ecological and economical system solutions is the wood-fired cogeneration power station in Hamburg-Lohbrügge, which generates some 13 million kilowatt hours of electricity from renewable resources every year. Only natural woodchips from forestry and landscaping work are used. The heat generated at the same time – some 60,000 MWh – is delivered to a neighbouring district heating plant, which supplies more than 8,000 households. Combined heating and power generation provide the best possible use of the energy contained in wood solid fuel – with a utilisation factor of 85%.
The owner, KWA Bioenergie GmbH und Co. Kraftwerk Lohbrügge KG, invested a total of EUR 13 million in the construction of the wood-fired cogeneration power station in Hamburg. The installation, which was designed by Schuler Consulting Engineers based in Bietigheim-Bissingen, cuts annual carbon dioxide output by some 23,000 tonnes.
At a second power station in Ludwigsburg that was designed by Schuler, a Demag process crane also ensures that the material is stored and the fuel is supplied efficiently and reliably.
Automated crane solution
Focus on automation
- Rapid clearance of the tipping positions
- Storage of the fuel materials in three pre-defined storage zones
- Supply of the wood-fired incineration system with the corresponding blend of fuel
- Load capacity: 11 t
- Span: 16,400 mm
- Lifting height: 24,500 mm
- Variable long/cross-travel and lifting speeds: 50 / 40 / 50 m/min.
- Multi-jaw grab: 8 m³ capacity
A clean solution
The wood-fired cogeneration power stations with their integrated silos were planned to achieve optimum utilisation of the space. For this reason, the solution with automatic cranes was given preference over stores served by wheel-loaders, for example. This alternative would not only have caused more exhaust fumes and higher noise emissions, but would also have required more staff to operate the store.
