  1. 1. Borne in Fire - A Study of Black Carbon Emitted from Coal Fired Power Plants in West Bengal, India.

    Master-uppsats, Linköpings universitet/Institutionen för tema

    Författare :Ra'eesah Hendricks; [2023]
    Nyckelord :Black Carbon; Chemothermal Optical Method; Health Impacts; Particulate Matter 2.5; Thermal Optical Reflectance Method;

    Sammanfattning : Black carbon has been reported to have major impacts on climate, environmental quality, and health. A chemothermal oxidation method, ordinarily used to isolate black carbon from soils, sediments and aquatic samples was applied to explore atmospheric samples. LÄS MER

  3. 2. A Comparison Between FDS and the Multi-Zone Fire Model Regarding Gas Temperature and Visibility in Enclosure Fires

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Benjamin Waldeck; [2020]
    Nyckelord :Enclosure fire; FDS; Multi-Zone Fire Model; gas temperature; Visibility; Technology and Engineering;

    Sammanfattning : When designing large buildings with complex geometry there is often a need for performance-based design and the use of computer models. CFD models like FDS that are available and validated for this purpose are typically time consuming and require large amounts of computing power. LÄS MER

  4. 3. Application of mass defect filtering and statistical analysis for non-target data mining of gas and soot data from a study testing different firefighting methods

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Danielle Ydstål; [2020]
    Nyckelord :;

    Sammanfattning : Due to the high temperatures during a fire event, a large variety of compounds are formed or released from burning materials, all of which have a varying degree of environmental effects. In an incidental fire there are several variables that are important for which and how much combustion products that are formed, including the burning material, ventilation (presence of air), and temperature.

  5. 4. DEVELOPMENT OF RISK INFORMED METHODS FOR ESTIMATING RADIATION RELEASE FROM CABLE FIRES AT HIGH ENERGY PHYSICS FACILITIES

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Daniel Funk; [2020]
    Nyckelord :Fire Safety Engineering; CERN; Fire-induced Radiological release; particle accelerator; Fire Protection; Fire Risk Analysis; Technology and Engineering;

    Sammanfattning : CERN operates the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator. The LHC was built to advance the state of knowledge in particle physics by increasing the energy of colliding particles to the TeV range. LÄS MER

  7. 5. Riskanalys av brand i avgassytem som avser dieselmotorer som opererar med låg belastning på fartyg

    M1-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Martin Bergkvist; [2019]
    Nyckelord :Exhaust gas boilers; economizer; soot fire; soot deposits; residual fuel oil; Avgaspanna; ekonomiser; brand; sotbeläggningar; och restoljor.;

    Sammanfattning : Med skenade bunkerkostnader och överdimensionerade motorinstallationer har allt fler handelsfartyg börjat operera under benämningen slow steaming, vilket innebär att sotbränderna har ökat i avgaspannor/ekonomiser och i en del extrema fall har branden övergått till en vätgasbrand. Arbetet utreder främst dieselmotorer som använder restoljor som bränsle och opererar med en låg motorbelastning. LÄS MER
