  1. 6. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

    Författare :Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. LÄS MER

  3. 7. On a Hydrogen Pellet Target for Antiproton Physics with PANDA

    Författare :Örjan Nordhage; Ulrich Wiedner; Eberhard Widmann; Uppsala universitet; []
    Nyckelord :Nuclear physics; PANDA; Internal target; Pellet target; Beam-target interaction; Vacuum; Tracking; D-meson decay length; Kärnfysik;

    Sammanfattning : The PANDA experiment is a part of the future FAIR accelerator facility and will study the strong interaction by detecting the reaction products from antiproton-proton annihilations in a near full solid-angle configuration. One option for the internal proton target in PANDA is frozen micro-spheres of hydrogen, so-called pellets. LÄS MER

  4. 8. Elbesparing med pelletkaminer och solvärme i direktelvärmda småhus

    Författare :Tomas Persson; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; Pellets; Kaminer; Småhus; uppvärmning; Solvärme; Elvärme; konvertering; Biobränsle; Systemlösningar;

    Sammanfattning : The aim of this study was to investigate how electricallyheated houses can be converted to using wood pellet and solarheating. There are a large number of wood pellet stoves on themarket. Many stoves have a water jacket, which gives anopportunity to distribute the heat to domestic hot water and aradiator heating system.

  5. 9. Particle emissions from wood pellet combustion

    Författare :Henrik Wiinikka; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Combustion of solid biomass under fixed bed conditions is a common technique to generate heat and power in both small and large scale grate furnaces (domestic boilers, stoves, district heating plants). Unfortunately, combustion of biomass will generate particle emissions containing both large fly ash particles and fine particles that consist of fly ash and soot. LÄS MER

  7. 10. Influence of Oxygen Enrichment on the Oxidation of a Magnetite Pellet Bed During Pot Furnace Induration

    Författare :Anna Eriksson; Charlotte Andersson; Hesham Ahmed; Timo Fabritius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxygen enrichment; Magnetite pellet bed; Oxidation; Pot furnace; Induration; Fossil-free ironmaking; Process Metallurgy; Processmetallurgi;

    Sammanfattning : This study was motivated by the excess oxygen that likely results from the current transition to hydrogen-based Swedish steel production. The potential usability of large amounts of oxygen in a process gas for iron ore pellet induration could improve the process efficiency in terms of fuel consumption and productivity. LÄS MER
