1. 21. Sustainable Energy Conversion from Biomass Waste Combustion

   Författare :Maulana Nugraha; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle modelling; furnace; particulate matter; Stefan flow; computational fluid dynamics CFD ; orthogonal collocation; biomass waste combustion;

   Sammanfattning : Various biomass-type conversions into sustainable heat and power, from dedicated crops to solid biomass waste via the combustion process, are at the center of scientific and industrial focus today. However, biomass combustion contribution to global particulate matter (PM) emission has become one of the biggest challenges that remain in the development of sustainable biomass combustion systems.

3. 22. Sustainable Energy Conversion from Biomass Waste Combustion - Experimental and Multiscale Modelling Studies

   Författare :Maulana Nugraha; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stefan flow; particulate matter; biomass; combustion; soot; furnace; orthogonal collocation; CFD simulation;

   Sammanfattning : The development of sustainable energy conversion via residual biomass combustion is one of the scientific and industrial community focus today to fulfilling the global net zero emission commitment in 2050. Despite its potency due to the abundant stock of biomass, hazardous particulate matter (PM) emission from residual biomass combustion remains a big challenge to increase the contribution of biomass combustion as a main renewable energy source.

4. 23. Compositional variability of settling organic particles in non-tidal coastal and shelf enviroments

   Författare :Mona Petersson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; vertical flux; particulate matter; amino acids; Skagerrak; Limfjorden; Geovetenskap; Earth sciences; Geovetenskap; naturgeografi; Physical Geography;

   Sammanfattning : The coupling between the composition of settling organic particles and near-bed dynamics was studied in non-tidal coastal and shelf environments. Field investigations were made in Skagerrak and Limfjorden between 1990 and 1995. LÄS MER

5. 24. Particle emissions from residential wood and biodiesel combustion

   Författare :Robin Nyström; Christoffer Boman; Dan Boström; Markus Broström; Michael Strand; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Combustion; biomass; wood; biodiesel; particulate matter; emissions; aerosols; physicochemical properties; size distribution; PAH;

   Sammanfattning : Emissions from anthropogenic combustion sources, such as vehicles and biomass combustion, contribute significantly to ambient particulate matter (PM) both on a local and global scale. Exposure to ambient PM and air pollution in general is linked to a variety of different health effects and it has been estimated that as many as 2. LÄS MER

7. 25. Elemental composition of fine particles: exposure in the general population and influence from different sources

   Författare :Peter Molnár; Göteborgs universitet; []
   Nyckelord :particulate matter; PM2.5; PM1; ultrafine particles; trace elements; personal exposure; X-ray fluorescence XRF ; indoor levels; air mass back trajectories; long-range transport; domestic wood burning;

   Sammanfattning : The general population is exposed to particulate air pollution from many different local and regional sources. Examples of local sources are traffic, biomass burning and resuspended dust, while regional sources are dominated by combustion processes from heating, traffic and industries. LÄS MER
