NOCOBI (Novel way to control the combustion of various biomasses)

The main goal of the project is to develop advanced new monitoring and control methods in order to avoid fouling and slagging in biomass boilers by utilizing modeling and novel measurement methods. Consequently, the usability of the boiler in combustion of biomasses with various compositions is improved. Increasing use of biomasses causes the quality of fuels to be more heterogeneous and therefore the properties of the ash vary as well. This easily results a growing deposition of ash on the inner surfaces of the boiler if the mixtures of fuel or process conditions are not optimal.

Project is carried out at University of Oulu in co-operation with Department of Process and Environmental Engineering and Department of Chemistry. In Mass and Heat Transfer Process Laboratory the main research methods are CFD modeling and new methods for measuring flue gas properties.
