  1. 1. Sintering in the Kraft Pulp Mill - Studies in the Rotary Kiln and Recovery Boiler

    Författare :Josefina Lindblom; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sintering; recovery boiler dust; recovery boiler; solid state diffusion; rotary kiln; lime mud; lime; sintering model; specific surface area;

    Sammanfattning : The conversion of black liquor to white liquor is carried out in the chemical recovery system, which is made up of several units; in two of them, i.e. the recovery boiler and the rotary kiln, sintering plays an important role. LÄS MER

  3. 2. NOx formation in iron ore rotary kilns

    Författare :Rikard Edland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; Grate-Kiln process; emissions control; combustion chemistry; Nitrogen oxides;

    Sammanfattning : Iron ore pellets are often produced using the so-called Grate-Kiln process, which is designed to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. The heat required for this process comes from the combustion of a pulverized fuel in a rotary kiln, involving the formation of a jet flame. LÄS MER

  4. 3. NOx Formation in Rotary Kilns for Iron Ore Pelletization

    Författare :Rikard Edland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rotary kiln; combustion chemistry; emissions control; Grate-Kiln process; Nitrogen oxides; NOx formation;

    Sammanfattning : The production of iron ore pellets is often performed in the so-called Grate-Kiln process. The aim of the process is to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing. LÄS MER

  5. 4. 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

  7. 5. Dusting in a lime kiln - Characterization of the material and unit operations

    Författare :Henric C O Dernegård; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terminal velocity; Dusting lime kiln; fines; lime mud filter; ESP-dust; reactivity;

    Sammanfattning : The present thesis describes the background of, and gives some points of orientation for, the phenomenon of dusting in the burner zone of a lime kiln. The aim of this study is twofold: to increase knowledge of the factors that influence the degree of dusting and also to investigate the effect a dusting lime kiln has on the white liquor preparation process.
