Biomass Combustion and Co-firing

Workshop on Development of torrefaction technologies and impacts on global bioenergy use and international bioenergy trade, Graz, Jan 2014

International workshop on 

Development of torrefaction technologies and
impacts on global bioenergy use and
international bioenergy trade

Friday , 17 January 2014,
– 18.10

Central European Biomass Conference (CEBC), Stadhalle, Graz, Austria

Task 32:
Biomass combustion and co-firing

Task 40:
Sustainable International Bioenergy trade

Workshop rationale and aim

Torrefaction is an interesting pre-treatment technology for biomass before pelletisation and/or combustion. It is a thermo-chemical process for the upgrading of biomass that is usually run at temperatures ranging from 250 to more than 300°C under the exclusion of oxygen and at ambient pressure.

Task 32, in co-operation with Task 40 andthe EU SECTOR  project organised a workshop on torrefaction

as a parallel session within the Central European Biomass Conference 2014 in Graz, Austria.

The presentations can be downloaded below. A summary of the presentations and conclusions of the round table discussion is available here.
