INTRODUCTION\u00a0<\/b><\/p>\n

Combustion of solid biomass offers the highest short-term
\npotential for significant CO2<\/sub>-reduction in energy production
\nof all renewable energy technologies in a cost-effectve manner.
\nComprehensive R&D work carried out during the last decades has
\nalready led to a state-of-the-art which allows a highly efficient
\ncombustion of a wide range of solid biomass fuels at high plant
\navailabilities as well as low gaseous emissions.<\/p>\n

However, several problems related to the formation of fine
\nparticulates during combustion, so called aerosols, are still unsolved.
\nThese problems affect both, the plant operation itself due to the
\nformation of deposits and ash mixtures with comparably low melting
\ntemperatures as well as particulate emissions. Therefore, a
\nconsiderable number of research projects has been initiated to find
\nsolutions for these technological problems. Aerosol immissions as well
\nas their impact on the human health are nowadays intensively
\ninvestigated and discussed.<\/p>\n

Against this background and to present and discuss on-going
\nresearch, IEA Bioenergy, Task 32, “Biomass Combustion and Co-firing” in
\nco-operation with the Austrian Bioenergy Centre and the Graz University
\nof Technology have organised an international seminar “Aerosols in
\nBiomass Combustion”. The seminar presented, discussed and assessed the
\nactual state-of-science in this field and provided information about
\nnon-technical issues especially related to legislative regulations,
\naerosol immissions and health effects of fine particulate immissions.
\nApproximately 70 researchers, furnace and boiler manufacturers, filter
\nmanufacturers as well as utilities, plant operators, energy agencies
\nand public authorities participated in the workshop.<\/p>\n

SUMMARY AND CONCLUSIONS<\/b><\/p>\n

One should clearly distinguish between old and new
\nbiomass combustion devices. This is of special importance if small-scale
\nunits are considered because new biomass furnaces achieve an almost
\ncomplete burn-out, which substantially reduces the amount of organic
\naerosols formed.<\/span><\/p>\n

Due to the fact that old small-scale biomass
\ncombustion plants emit significantly larger amounts of aerosols (due to
\nincomplete combustion) than new systems, aerosol emissions from biomass
\ncombustion could be substantially reduced by replacing old with new
\nautomatically operated small-scale biomass combustion devices or at least
\nby improving the operation of old systems (e.g. by the installation of
\nstorage tanks).<\/span><\/p>\n

Inventories concerning aerosol emissions and
\nimmissions need actual and secured data. New data con\u00adcerning aerosol
\nemissions from biomass combustion (based on measurements per\u00adformed
\nwithin ongoing R&D projects) should therefore be supplied for new as
\nwell as old combustion devices as well as concerning the actual ratio
\nbetween old and new systems installed in a certain country. These data are
\nof great relevance in order to achieve correct calculations and
\nevaluations regarding the influence of aerosols from biomass combustion on
\nthe overall emission and immission situation.<\/span><\/p>\n

Regarding health effects of aerosols from
\nbiomass combustion, first studies are ongoing but there is still a long
\nway to go in order to understand which influencing variables are of rele\u00advance
\n(e.g. particle size, chemical composition). Besides cell tests also
\ninhalation tests will be necessary to evaluate health effects properly.<\/span><\/p>\n

First sets of release data, describing the
\namount of aerosol forming species released to the gas phase during
\ncombustion, are available for pulverised biomass fuels as well as for
\ngrate com\u00adbustion systems and will also be further investigated. These
\ndata are of great relevance for aerosol formation as well as for
\nsubsequent deposit formation modelling.<\/span><\/p>\n

Aerosol formation models for biomass combustion
\nsystems have already achieved a high level of development and will be
\nfurther improved within the next years. These models are of great
\nrelevance to understand aerosol formation pathways as well as relevant
\ninfluencing variables.<\/span><\/p>\n

Moreover, relevant investigations regarding the
\ninfluence of aerosols on deposit formation have been performed and have
\nshown that aerosols can strongly influence the ash melting behaviour of
\ndeposits due to the formation of salt mixtures with low melting points.<\/span><\/p>\n

New small-scale aerosol precipitation devices
\nare under development. Tests with prototypes have started but these
\ntechnologies are not yet commercially available.<\/span><\/p>\n

Medium and large-scale biomass combustion plants
\n(nominal boiler capacity > 500 kWth<\/sub>) can precipitate
\naerosols well if appro\u00adpriate filters are installed. An efficient aerosol
\nprecipi\u00adtation can be achieved by electrostatic precipitators as well as
\nby baghouse filters.<\/span><\/p>\n
