1. 6. Particulate and gaseous emissions from residential biomass combustion

   Författare :Christoffer Boman; Anders Nordin; Ingwald Obernberger; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; aerosols; air pollution; emissions; fuel pellets; residential biomass combustion; inorganic characterization; incomplete combustion; particulate matter; polycyclic aromatic hydrocarbons; trace elements; Kemi; Chemistry; Kemi;

   Sammanfattning : Biomass is considered to be a sustainable energy source with significant potentials for replacing electricity and fossil fuels, not at least in the residential sector. However, present wood combustion is a major source of ambient concentrations of hydrocarbons (e.g. LÄS MER

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

   Sammanfattning : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

4. 8. Combustion of agricultural residues : Application for Stirling micro-combined heat and power

   Författare :Evelyn Cardozo; Torsten Torsten Fransson; Carlos Augusto Santos Silva; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

   Sammanfattning : Access to energy services is crucial for the development of countries. Therefore, in developing countries, the access to modern conversion technologies would contribute to reduce the poverty, improve health services and promote the economy especially in rural areas. Around 2.5 billion people in these countries use biomass for cooking. LÄS MER

5. 9. Carbonaceous Aerosol in Europe - out of the woods and into the blue?

   Författare :Jan Robert Bergström; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organic aerosol; elemental carbon; chemical transport modelling; residential wood combustion; biotic stress induced emissions; source apportionment; EMEP MSC-W model;

   Sammanfattning : Particulate matter (PM) in the atmosphere influences weather and climate and may have important health impacts. Regional scale chemical transport modelling aims to describe the composition of particulate matter, to track different sources, estimate their relative importance, and to give realistic predictions of responses to changes in emissions and atmospheric conditions.

7. 10. Residential biomass combustion - emissions of organic compounds to air from wood pellets and other new alternatives

   Författare :Maria Olsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Burning; methoxy¬phenol; benzene; stove; ecolabel; oats; wheat straw; firewood; boiler; hydrocarbon; smoke; peat;

   Sammanfattning : It is important to increase the use of biofuels for residential heating in order to decrease the use of fossil fuels and their impact on global warming. The smoke from the combustion of biomass contains a large number of compounds, which to varying degrees can affect the environment and human health. LÄS MER
