Workshop on CFD for design of industrial biomass combustion systems, Copenhagen, May 2013

IEA Bioenergy Task 32 workshop:

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

organised as side event of the

European Biomass Conference and Exhibition
Copenhagen, Denmark
Thursday 6 June 2013

CFD based design tools have significantly improved in the last decade and
are commonly applied for larger utility boiler installations. It can
lead to much better combustion quality and avoid the need of a ‘try and error’ approach for boiler design and reducing development expenses.An expert workshop was held as
a side event of the EU Biomass Conference 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.
The agenda with downloadable
presentations is provided below.
