  4. 3. 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

  5. 4. Microcalorimetry and Infrared Spectroscopy : Thermal processes related to solid waste, ageing rubber, phase change materials, and biomass gasification
