  1. 1. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Andras Szanthoffer; [2022]
    Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER

  3. 2. Building with pollution

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Zornitsa Hristova Kovacheva; [2021]
    Nyckelord :Arts and Architecture;

    Sammanfattning : Black carbon is an ever-growing global problem and one of the most important environmental issues of this generation. Black carbon, also known as soot, is a highly polluting substance and it is the second-largest polluter after carbon dioxide. 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
