  1. 1. CFD in the design of gas quenching furnace

    University dissertation from Stockholm : KTH

    Author : Olivier Macchion; Said Zahrai; Bengt Sunden; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Gas quenching; modeling; CFD; gas mixtures; uniformity.; Numerisk analys; MATHEMATICS Applied mathematics Numerical analysis; MATEMATIK Tillämpad matematik Numerisk analys;

    Abstract : This thesis focuses on the numerical and theoretical studies of gas quenching in industrial furnaces. Gas quenching is the rapid cooling of metal pieces, aiming at forcing a phase transformation of the metal structure to improve its mechanical properties. READ MORE

  2. 2. Some aspects on the reduction of olivine pellets in laboratory scale and in an experimental blast furnace

    University dissertation from Stockholm : Materialvetenskap

    Author : Jerker Sterneland; [2002]
    Keywords : Olivine; pellets; pellet testing; reduction softening melting; MPBO; blast furnace; reduction; quenching; dissection; coating; sticking; coated pellets;

    Abstract : The reduction behaviour of the olivine iron ore pellet MPBOwas studied in laboratory scale at KTH as well as in the LKABexperimental blast furnace. Initially, a newreduction-under-load, or so-called reduction/softening/melting,test equipment was developed. READ MORE

  3. 3. Competitive Protein Adsorption during Spray-drying

    University dissertation from Britt Nyström, Library, Institute for Surface Chemistry, P.O.B. 5607, 114 86 Stockholm, Sweden

    Author : Karin Landström; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; pyrene; quenching; fluorescence; beta-casein; beta-lactoglobulin; bovine serum albumin; milk proteins; Spray-drying; competitive adsorption; Surface and boundary layery chemistry; Ytkemi; gränsskikt;

    Abstract : The aim of this thesis was to study competitive adsorption of milk proteins during spray-drying. For this purpose, a new surface sensitive method was developed which measures the quantitative amount of specific proteins at the powder surface. READ MORE

  5. 5. Thermal formation and chlorination of dioxins and dioxin-like compounds

    University dissertation from Umeå : Kemi

    Author : Stina Jansson; Stellan Marklund; Mats Tysklind; Jochen F. Müller; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dioxin; dioxin-like compounds; isomer distribution pattern; homologue profile; injection; O2PLS; PCDD; PCDF; PCN; PCBz; PCPh; MSW combustion; formation; chlorination; flue gas; quench profiles; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Abstract : This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (ashes and filters) are highly toxic and are classified as hazardous waste.
