The project focuses on R&D concerning ash related problems ?n biomass combustion and co-firing of biomass in coal fired plants. The main objectives of the project will be to investigate the release of ash forming compounds from biomass fuels in fixed-bed and pulverised fuel combustion systems, to determine presently not available thermodynamic data concerning the melting behaviour of Na, Zn and Pb-rich ashes, to further develop simulation tools for aerosol and deposit formation and to develop and test a new technology (an aerosol condenser) for efficient and cost effective aerosol precipitation in small-scale biomass combustion units. The project will also investigate the influence of particulate emissions from biomass combustion and co-firing plants on the regional air quality and parameters influencing health effects caused by these emissions. Comprehensive laboratory, pilot-scale and large-scale test runs at biomass combustion and co-firing plants as well as modelling of relevant mechanisms for aerosol and deposit formation will form the basis of the work performed and will complement each other. By reaching the aims of the project deposit formation in biomass combustion and co-combustion shall be significantly reduced by optimisation of furnace and boiler designs as well as control systems and by a better choice of fuel blends used. Concerning small-scale biomass combustion, aerosol emissions will significantly be reduced by the application of the new precipitation technology. New data concerning the influence of particulate emissions from biomass combustion and co-firing on health risks will be evaluated and form the basis for a recommendation of emission limits. The project results will contribute to a higher energy efficiency and availability of biomass combustion and co-firing plants and to a significant reduction of aerosol emissions from small-scale biomass combustion plants, promoting the increased use of biomass for energy production in Europe.
