  1. 11. Drying and Pyrolysis of Logs of Wood

    Författare :Jenny Larfeldt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; structural changes; heat transfer properties; pyrolysis; drying; single particle; wood;

    Sammanfattning : This work concerns log firing in small-scale boilers for house heating, which in Sweden meets a heat demand of 12 TWh a year. In boilers used for domestic central heating in the sizes of 10 to 30 kW the predominant combustion technique is grate firing. LÄS MER

  3. 12. Industrial Wood Drying : Airflow Distribution, Internal Heat Exchange and Moisture Content as Input and Feedback to the Process

    Författare :Tommy Vikberg; Mihaela Campean; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : At a sawmill, the most energy demanding process is the wood drying. The drying process also has a great impact on quality parameters determined for the boards in the final sorting and thereby affects the sales value to a great extent. LÄS MER

  5. 14. Drying kinetics, coalescence and agglomeration of dairy products particles

    Författare :Loredana Malafronte; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single particle; stickiness; agglomeration; spray drying; modelling; drying-kinetics; coalescence; dairy;

    Sammanfattning : Spray drying is used in the food, pharmaceutical, and chemical industries for producing powder from a liquid feed. The unique advantages of spray drying are producing powders of a specific particle size and moisture content, handling heat sensitive products, and high capacity. However, spray drying is a complex process. LÄS MER

  7. 15. 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.
