  1. 11. Fire Safety of Facades

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Bogdan-Grigore Branisteanu-Albulescu; [2019]
    Nyckelord :polystyrene; graphene; façade; pyrolysis; Technology and Engineering;

    Sammanfattning : Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. LÄS MER

  3. 12. Determination of Thermal Conductivity of Wood Exposed to Fire based on Small Scale Laboratory Trials for Finite Element Calculations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Johnny Chung; [2017]
    Nyckelord :Wood; Cone Calorimeter. Conductivity; Fire; Temperature; TASEF; Finite element method; Trä; Konkalorimeter; Konduktivitet; Brand; Temperatur; TASEF; Finita elementmetoden;

    Sammanfattning : This study describes an approach to determine the thermal conductivity of wood at elevated temperatures. The aim is to be able to use the developed conductivity as input in structural elements in finite element calculations. LÄS MER

    Sammanfattning : The aim of this thesis is to study the flammability and fire spread for textile membranes for weather protection. This thesis includes literature studies to determine current standards and recommendations available. Main focus however have been on the European classification system EN 13501-1 and construction site safety. LÄS MER

  5. 14. Brandrisker vid lägre syrehalter – Experiment i konkalorimetern

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Erik Linnå; Viktor Wahlström; [2014]
    Nyckelord :CACC; carbon dioxide; carbon monoxide; cone calorimeter; controlled atmosphere; fire risk; heat release; HRR; hypoxic air; mass loss rate; oxygen; particle board; time to ignition; brandrisk; effekt; effektutveckling; koldioxid; kolmonoxid; konkalorimeter; LTH; massavbrinningshastighet; spånskiva; syrehalt; tid till antändning; Technology and Engineering;

    Sammanfattning : This report has been conducted to examine the advantages and disadvantages of using an open system for experiments in the cone calorimeter with a vitiated air enclosure at low oxygen levels. Eight different experimental set-ups were conducted in which two were designed according to ISO 5660, i.e. the cone calorimeter in its standard configuration. LÄS MER

  7. 15. Functional performance criteria for comparison of less flammable transformer oils with respect to fire and explosion risk

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Denis Hellebuyck; [2013]
    Nyckelord :Flammability; transformer oils; fire and explosion risk; cone calorimeter test; Technology and Engineering;

    Sammanfattning : Power grids worldwide are expanding not only driven by ambitious clean energy, but also because of the rising need for reliable energy. Key components of these power grids are transformers. Transformers are traditionally filled with mineral oil, to serve as a coolant and dielectric insulator. LÄS MER
