  1. 1. Through air drying Thermographic studies of drying rates, drying non-uniformity and infrared assisted drying

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Aron Tysén; Karlstads universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Through air drying; TAD; Drying; Dewatering; Water removal; Infrared drying; Non-uniformity; Variability; Formation; Thermography; Tissue; Fabric; Wire; Pulp; Grammage; Chemical Engineering; Kemiteknik;

    Sammanfattning : The removal of water is an integral part of papermaking. The drying process is responsible for a great share of the energy used in the paper machine. Premium grade tissue products are dried by through air drying. Large volumes of natural gas are burned to heat the air drawn through the paper web to achieve the drying. LÄS MER

  2. 2. Through air drying The influence of formation and pulp type on non-uniform drying and air flow

    Detta är en avhandling från Karlstad : Karlstads universitet

    Författare :Aron Tysén; Karlstads universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Dewatering; Water removal; Moisture; Non-uniformity; Variability; Tissue; TAD; Through air drying; Thermography; Formation; Pulp; Chemical Engineering; Kemiteknik;

    Sammanfattning : The removal of water is an integral part of tissue paper production. Through air drying (TAD) is used for water removal when producing premium tissue grade products, however, at the price of higher energy demand. A better understanding of TAD may therefore lower the energy demand. LÄS MER

  3. 3. Development towards an efficient and sustainable biofuel drying

    Detta är en avhandling från Växjö University Press

    Författare :Peter Bengtsson; Växjö universitet.; [2009]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; biomass; bioenergy; drying; bed drying; drying zone; modeling; VOC; terpenes; wood fuels; wood chips; sawdust; Norway spruce; Scots pine;

    Sammanfattning : The usage of biofuel as well as wood fuel has increased in Sweden and all of Europe during recent decades, and there are several reasons to believe that this increase will continue. An important reason for this increase is that the environmental and climate problems caused by fossil fuels are becoming even more evident. LÄS MER

  4. 4. Energy Efficient Textile Drying

    Detta är en avhandling från Fakulteten för teknik- och naturvetenskap

    Författare :Lena Brunzell; Karlstads universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tumble dryer; drying; textile; energy and mass balance; control strategy; TECHNOLOGY Engineering mechanics; TEKNIKVETENSKAP 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

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

    Detta är en avhandling från Fakulteten för teknik- och naturvetenskap

    Författare :Peter Mellbo; Högskolan i Kalmar.; [2007]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ash products; Wood ash; Leaching; Drying; Nutrient; ; Sustainable forestry; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING Plant production Forestry; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING Växtproduktion 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
