Grate furnace
...for fuel particle sizes up to P200*
In our grate systems, the reciprocating grate is integrated into the combustion chamber of the natural circulation boiler. The staged air supply ensures an efficient combustion process.
Suitable fuels for grate furnace:
- Natural biomass
- Landscape conservation material, bark, waste wood AI - AIII
*According to DIN EN ISO 17225-1
Bubbling fluidized bed
...for fuel particle sizes up to P100*
Your decisive advantage with our fluidized bed boiler system is greater flexibility in fuel use combined with low raw gas emissions. This results in reduced consumption of operating resources. At the same time, you can achieve a higher load change rate and system availability. In our bubbling fluidized-bed firing system, the open nozzle pockets are integrated into the combustion chamber of the natural circulation boiler.
Suitable fuels for fluidized bed technology:
- Untreated biomass, landscape conservation material, bark, waste wood AI - AIV
- Agricultural waste such as chicken manure
- Paper rejects, fiber sludge, RDF
*According to DIN EN ISO 17225-1
Boiler technology
We plan the concept of your power plant precisely for the desired fuels and your requirements to deliver a highly efficient and tailore-made solution.
We can plan the following components:
- Fuel systems
- Flue gas cleaning systems
- Steam turbine and generator
- Balance of plant
- Air- or water-cooled condenser
Flue gas cleaning
...to comply with emission limits with low fuel consumption
To ensure that your power plant complies with the applicable emission limits at all times, we plan a customized flue gas cleaning system. We implement this optimally into the overall process.
The following system components can be used:
- SNCR or SCR systems to reduce NOx emissions
- Electrostatic precipitators or cyclones as dust pre-separators
- Fabric filters, if required with reactor and additive dosing, for the reduction of SO2, HCl, HF and heavy metals through a dry sorption process
