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

    Author : Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; Karlstads universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure

    Author : Sara Axelsson; Ulrika Nilsson; Kåre Eriksson; Håkan Westberg; Martin Harper; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rosin; resin acids; HPLC ESI-MS; air sampling; urine samples; wood pellets; wood dust; Analytical Chemistry; analytisk kemi;

    Abstract : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. READ MORE

  6. 4. Improving Wood Fuel Pellets for Household Use : Perspectives on Quality, Efficiency and Environment

    Author : Magnus Ståhl; Bengt Månsson; Johan Vinterbäck; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; quality; efficency; environment; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Bioenergy is one of many contributors to reducing the use of fossil fuels in order to mitigate climate change by decreasing CO2-emissions, and the potential for biofuels are large. The wood fuel pellets are a refined biofuel made of sawdust, which is dried and compressed to achieve improved fuel and transportation properties. READ MORE
