  2. 1. Mineral Reactions and Slag Formation During Reduction of Olivine Blast Furnace Pellets

    Author : Elin Ryösä; Hans Annersten; Kyösti Heinänen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olivine; iron ore pellets; blast furnace; reduction; alkali; coating; slag formation; Earth sciences; Geovetenskap;

    Abstract : The present work focuses on mineral reactions and slag formation of LKAB olivine iron ore pellets (MPBO) subjected to reducing conditions in the LKAB experimental blast furnace (EBF). The emphasis is on olivine reactions with surrounding iron oxides. Many factors influence the olivine behaviour. READ MORE

  4. 2. Characterization of conversion zones in a reciprocating grate furnace firing wet woody biomass

    Author : Narges Razmjoo; Strand Michael; Chungen Yin; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass combustion; Grate firing; Fuel bed; Moisture; Gas phase; Conversion zone; Experimental; Temperature distribution; Gas analysis; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Grate-firing systems are a common and popular combustion technology for burning biomass. However, combustion of biomass in these furnaces may emit a large amount of pollutants in the form of CO, CH4, PAH, NOx, and particles. READ MORE

  5. 3. Crystallization of glasses in the system (Zr)-Y-Si-Al-O-(N)

    Author : Peter Vomacka; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Abstract : Glass is a group of materials that has been used for structural and functional purposes for many centuries. Nevertheless, interest in the science and technology of glass has expanded significantly in recent years as a result of the need to develop new materials for advanced applications. READ MORE

  6. 4. Mineralogical influence of different cooling conditions on leaching behaviour of steelmaking slags

    Author : Fredrik Engström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : The Swedish steelmaking industry produces large amounts of by-products. In 2006, the total amount of slag produced reached approximately 1 375 000 metric tons, of which 30% was deposited. Due to its strength, durability and chemistry, steel slag is of interest in the field of construction due to it's similarities with ordinary ballast stone. READ MORE

  7. 5. Hybrid fiber preform fabrication using CO laser heating

    Author : Taras Oriekhov; Michael Fokine; Cruz José; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Preform; CO laser; silicon-core fiber; semiconductor-core fiber; specialty fiber; optical fiber.; Optik och fotonik; Optics and Photonics;

    Abstract : This thesis describes the development of a new prototyping technique for specialty optical fibers and covers all the fabrication steps from preform to fiber. The technique allows to produce fibers of a custom core structure and material composition, mainly focusing on semiconductor core fibers. READ MORE
