  1. 1. Drying of Multicomponent Liquid Films

    Författare :Fabio Luna; KTH; []
    Nyckelord :ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

    Sammanfattning : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. LÄS MER

  3. 2. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics

    Författare :Peter Mellbo; Tommy Claesson; Sirkku Sarenbo; Hans Samuelsson; Högskolan i Kalmar; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ash products; Wood ash; Leaching; Drying; Nutrient; ; Sustainable forestry; Forestry; Skogsskötsel; Miljövetenskap; Environmental Science;

    Sammanfattning : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. LÄS MER

  4. 3. 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. 4. A new measurement method to analyse the thermochemical conversion of solid fuels

    Författare :Rasmus Friberg; KTH; []
    Nyckelord :Packed-bed combusion; thermochemical conversion of biomass; solid-fuel combusion; fuel-bed combusion; gate combusion; biomass combusion; gasification. Pyrolysis; drying;

    Sammanfattning : The firing of fuel wood has been identified as one of themain causes of pollutant emissions from small-scale (.... LÄS MER

  7. 5. Wood colour related to kiln drying

    Författare :Bror Sundqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : Raised temperature in artificial drying has led to some changes of wood products such as colour and strength etc. For special treatment of wood-products with clearly modified properties, among them colour, is often high temperature and steam used industrially. LÄS MER
