Workshop: CFD aided design and other design tools for industrial biomass combustion plants

IEA Bioenergy Task 32 organises an expert workshop for equipment suppliers and researchers to share practical experiences and address the current opportunities and limitations of CFD based design of industrial biomass combustion appliances.

CFD tools can be very effective in the design of industrial biomass combustion installations. The approach can lead to much better combustion quality and avoid the need of a ‘try and error’ approach for boiler design and reducing development expenses. CFD based design tools have significantly improved in the last decade and are commonly applied for larger utility boiler installations.

The expert workshop will be held as a side event of the EU Biomass Conference in Copenhagen, Denmark.
