\nWorkshop rationale and aim<\/span><\/h1>\n


\nMost recently, fine particulate pollution gave rise to debate in
\nnumerous European countries as concentration limits were overstepped
\nmore frequently and more clearly than in the past. Urban areas were
\nespecially affected. Industry, traffic, agriculture and residential
\nheating proof mainly responsible for high fine particulate emission
\nlevels. In Austria for instance, within the residential heating sector
\nsmall-scale biomass combustion plants are responsible for about 88% of
\nthe PM10<\/sub> emissions, most of them (about 86%) are <\/span>
\npoorly controlled old
\nbiomass combustion systems.<\/span><\/p>\n


\nCompared to oil or natural gas, biomass contains a considerable amount
\nof ash. This inevitably leads to fly ash emissions during combustion. In
\nmedium and large-scale biomass combustion systems fly ash emissions are
\ntypically efficiently precipitated by appropriate filters (ESP or
\nbaghouse filters). Small-scale (residential) biomass combustion plants
\nhowever, are not equipped with filters due to economic reasons and the
\nimmature status of the technology. Fly ash emissions of complete biomass
\ncombustion, which is usually achieved by modern and automatically
\ncontrolled small-scale biomass combustion plants, consist mainly of
\ninorganic aerosols and are related to the PM1 fraction (particulate
\nmatter with a particle size smaller 1.0 \u00b5m). Carbonaceous aerosols are a
\nproduct of incomplete combustion, which is often the case in poorly
\ncontrolled old biomass combustion systems or natural draught systems
\n(like chimney stoves or tiled stoves), and consist of elementary carbon
\n(soot) or condensed hydrocarbon compounds (organic aerosols). Moreover,
\nold residential heating systems emit considerably higher PM1 emissions
\nthan modern small-scale biomass combustion systems. The formation of
\ncarbonaceous aerosols can be notably reduced by technical measures
\nconcerning combustion and process control technology (primary measures).
\nThe formation of inorganic aerosols however cannot be significantly
\nprevented in the same way but needs new \u201cLow-Dust combustion\u201d
\ntechnologies or requires secondary measures such as dust precipitators.<\/span><\/p>\n


\nFine particulate matter is the thoracic fraction out of total
\nparticulate matter, i.e. the fraction that can pass the larynx and reach
\nthe lung. There is strong epidemiologic indication that particulate
\nmatter in air has serious adverse health effects, but there are also
\nindications that there exist considerable differences regarding the
\ntoxicological effects between inorganic aerosols and <\/span>
\ncarbonaceous <\/span>
\naerosols, which is of great
\nrelevance for the environmental evaluation of different small-scale
\nbiomass combustion technologies.<\/span><\/p>\n


\nThe workshop accommodated the aforementioned issues by its three key
\ntopics “Low-Dust combustion technologies”, “Small-scale precipitators”
\nand “Health effects” and thus gave a comprehensive overview of
\nongoing developments and recent findings.<\/span>The
\nevent took place as a parallel session within the 3rd<\/sup>
\nCentral European Biomass Conference 2011 in Graz, Austria.<\/span><\/p>\n
