  2. 1. Experimental and Theoretical Study of Rack Storage Fires

    Author : Haukur Ingason; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; response time; in-rack sprinkler; flame heat transfer; gas velocity; gas temperature; flame height; in-rack fire plume; Rack storage fire; fire growth rate; Technological sciences; Teknik;

    Abstract : A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. READ MORE

  4. 2. Uptake and toxicity of brominated flame retardants and pesticides : Studies on littoral organisms and model communities

    Author : Kerstin Gustafsson; Nils Kautsky; Kirsten Christoffersen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aquatic ecotoxicology; ecological interactions; indirect effects; model community studies; toxicity; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : In this thesis, brackish and freshwater littoral model communities (microcosms) of varying size and complexity were used to study the effects of brominated flame retardants (BFRs) and pesticides. The brackish water microcosms consisted of natural water, sediment and associated organisms, while the larger freshwater microcosms also contained submersed macrophytes (Elodea canadensis).

  5. 3. Fires in Narrow Construction Cavities : Fire Dynamics and Material Fire Performance

    Author : Karlis Livkiss; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire; Ventilated façade; flame height; Stone wool; expanded polystyrene; Fire Dynamics Simulator FDS ;

    Abstract : There have recently been devastating fire incidents related to fire spread over ventilated façades. These incidents indicate gaps in our understanding of the fire behaviour of façades. This thesis takes a bottom-up approach to investigating fire behaviour in materials and elements associated with narrow cavities in modern constructions. READ MORE

  6. 4. Entrained flow gasification of biomass: soot formation and flame stability

    Author : Burak Göktepe; Kevin Whitty; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Entrained flow gasification (EFG) is a well-proven, commercially available technology for large scale coal gasification processes, with a production of a high quality syngas (a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4) and other compounds). For biomass, the process is still under development and there are several hurdles that must be cleared before it can become commercial. READ MORE

  7. 5. Laser-Induced Incandescence and Complementary Diagnostics for Flame Soot Characterization

    Author : Nils-Erik Olofsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Olofsson;

    Abstract : This work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. READ MORE
