  1. 1. Wood Fuel Pellets: Sawdust Drying in the Energy System

    Författare :Magnus Ståhl; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood fuel pellets; sawdust; drying; pellet production; recirculation; VOC; system integration; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : In 2004, the amount of wood fuel pellets used in Sweden was 1 256 000 tons, it was mostly used in large scale burning for district heating. Over the last 10 years, a significant increase in pellet production has occurred and today the preferred raw materials for pellet production, i.e., dry sawdust and wood shavings, are insufficient.

  3. 2. Energy Efficient Textile Drying

    Författare :Lena Brunzell; Bengt Månsson; Roger Renström; Jonas Berghel; Odilio Alves-Filho; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tumble dryer; drying; textile; energy and mass balance; control strategy; Engineering mechanics; Teknisk mekanik; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : Traditionally, textiles were dried outdoors with the wind and the sun enhancing the drying process. Tumble dryers offer a fast and convenient way of drying textiles independent of weather conditions. Tumble dryers, however, consume large amounts of electrical energy. LÄS MER

  4. 3. Through-Drying of Tissue Paper - Experiments and Modelling

    Författare :Henrik Weineisen; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper drying; modelling; TAD; through-drying; through-air drying; tissue; paper;

    Sammanfattning : In through-drying of paper, the energy required for drying is supplied by hot air, which is forced through the paper structure. The area for heat and mass transfer is the internal surface area of the paper, which is often many times larger than the external web surface area (xy-plane). LÄS MER

  5. 4. Verktyg för optimering av byggtorkning

    Författare :Peter Brander; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; konstroller; fukt; kostnader; byggkonstruktioner; byggnadskonstruktion; controls; tools; system; risks; costs; Building materials; optimizing; drying; Building construction; byggnadsmaterial; moisture; byggtorkning; verktyg;

    Sammanfattning : För att bättre kunna kostnadsoptimera byggtorkningar har ett optimeringsverktyg innefattande ett antal olika beräknings och bedömningsparametrar tagits fram. Byggtorkning innefattar stora kostnader för energi, provisorier och kontroller. LÄS MER

  7. 5. From Laboratory to System. Studies of Superheated Steam Drying of Biofuel

    Författare :Hans Björk; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; energy-system; dynamic; superheated steam drying; equilibrium moisture content; organic emissions; life cycle assessment LCA ; biofuel; optimisation; design;

    Sammanfattning : Replacement of fossil fuels by more sustainable fuels such as biofuels has become increasingly important during the last decade. This is mainly due to economical and environmental reasons. LÄS MER
