  2. 1. Energy Efficient Textile Drying

    Author : Lena Brunzell; Bengt Månsson; Roger Renström; Jonas Berghel; Odilio Alves-Filho; Karlstads universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. An Analytical Solution Applied to Heat and Mass Transfer in a Vibrated Fluidised Bed Dryer

    Author : Apolinar Picado; Joaquín Martínez; Göran Lindbergh; Ivars Neretnieks; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analytical solution; Heat and mass transfer; Temperature and moisture distribution; Drying modelling; Multicomponent drying; Drying selectivity; Volatile retention; Ternary mixture; Drying of particulate materials; Vibrated fluidised bed dryer; Chemical engineering; Kemiteknik;

    Abstract : A mathematical model for the drying of particulate solids in a continuous vibrated fluidised bed dryer was developed and applied to the drying of grain wetted with a single liquid and porous particles containing multicomponent liquid mixtures. Simple equipment and material models were applied to describe the process. READ MORE

  5. 3. Heat Transfer and Energy Efficiency in Infrared Paper Dryers

    Author : Magnus Pettersson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental; modelling; electricity; gas; efficiency; energy; drying; dryer; heat transfer; radiation; paper; infrared; IR; coating; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : Infrared (IR) dryers are widely used in the paper industry, mainly in the production of coated paper grades. The thesis deals with various aspects of heat transfer and energy use in infrared heaters and dryers as employed in the paper industry. Both gas-fired and electric IR dryers are considered and compared. READ MORE

  6. 4. Strategies for Reduced Energy Use and Cost in Pulp and Paper Mills by Energy Integration of the Paper Drying Process

    Author : Kristian Lindell; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper; Pappers- och massateknik; pulp and paper technology; Wood; Energiforskning; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Combined dryer; Energy research; Black liquor gasification; Heat recovery; Secondary energy; Co-generation; Costs; Energy; Drying;

    Abstract : The cost of energy for drying paper is substantial for the pulp and paper industry, and studies of various strategies for energy cost reductions such as increased energy efficiency, increased heat recovery from the exhaust drying air and reduced cost of the process heat are presented in this thesis. The energy use and cost studies were performed using a block-model based simulation tool developed for this specific purpose. READ MORE

  7. 5. Wood Fuel Pellets: Sawdust Drying in the Energy System

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

    Abstract : 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.
