Bioenergy Sustainable energy supply 

The Bioenergy research group is committed to the optimal use of biomass for generating heat and electricity. The research group, in cooperation with industrial partners, develops new methods for combustion and for the reduction of pollutant emissions.

Multistage combustion

The combustion process is composed of multiple stages to ensure optimal burnout quality of the biomass. Each part of the process is individually modeled and subjected to experimental investigations.

Furnace design

To reduce the pollutant emissions in biomass furnaces and at the same time increase efficiency, the combustion chambers are analyzed with computational fluid dynamics CFD to optimize efficiency and the results are experimentally validated with particle image velocimetry PIV.

Fine particulates from combustion processes

The fine particulates generated in combustion processes are harmful to health. As wood furnaces contribute to the build-up of fine particulates, the mechanisms of their formation are examined and measures for reducing particulate emissions are developed.

Optimization of electrostatic separators

At present, electrostatic separators are predominantly used for reducing the levels of fine particles in wood furnaces. To be available to various users these separators must be adjusted to changing operating states and to a wide range of particulate properties.
